Petitioner Anthony Bertolotti, a Florida prisoner under sentence of death, appeals the district court’s denial of his petition for the writ of habeas corpus. Concluding that Bertolotti’s claims lack merit, we affirm the judgment of the district court.
I. PROCEDURAL HISTORY
Bertolotti was convicted of first-degree murder for the September 1983 slaying of Carol Miller Ward in Orlando, Florida. The jury returned a general verdict of guilty upon a charge of felony murder and premeditated murder, both of which are death-eligible crimes under Florida law, Fla.Stat. Ann. § 782.04(l)(a); by a vote of nine to three, the jury recommended the death penalty, which the judge imposed on April 12, 1984. The Florida Supreme Court affirmed Bertolotti’s conviction and sentence on direct appeal, Bertolotti v. State, 476 So.2d 130 (Fla.1985), and Bertolotti voluntarily dismissed a subsequent petition for certio-rari filed in the United States Supreme Court. After the Governor of Florida signed a warrant for Bertolotti’s execution, Bertolotti filed in the Florida courts two collateral attacks on his conviction. The Florida courts held an evidentiary hearing and granted a temporary stay of execution, effectively nullifying the first execution warrant, but ultimately denied Bertolotti relief. See Bertolotti v. Dugger, 514 So.2d 1095 (Fla.1987) (denying state writ of habe-as corpus) and Bertolotti v. State, 534 So.2d 386 (Fla.1988) (denying Fla.R.Crim.P. 3.850 motion for post-conviction relief).
On January 31, 1989, the Governor of Florida signed a second warrant for Berto-lotti’s execution.1 On February 14, 1989, *1508Bertolotti filed in federal district court a motion for stay of execution and a petition for the writ of habeas corpus. The petition, Bertolotti’s first in federal court, presented eleven grounds for relief:
1. Trial counsel provided Bertolotti with ineffective assistance of counsel when counsel failed to adequately investigate, develop and present defenses at the guilt and penalty phases of Berto-lotti’s capital trial.
2. The trial court erred by denying Ber-tolotti’s motions for a mistrial based on the prosecutor’s improper closing argument at the sentencing phase of the trial.
3. The trial court’s denial of Bertolotti’s requested penalty phase instruction informing the jury of its ability to exercise mercy deprived Bertolotti of a reliable and individualized capital-sentencing determination.
4. The trial court in its instructions at sentencing unconstitutionally shifted the burden of proof to Bertolotti.
5. The Florida courts have given an im-permissibly broad construction to the term “especially heinous, atrocious or cruel” as that term is used in a statutory aggravating circumstance which was found to justify Bertolotti’s death sentence.
6. Bertolotti’s death sentence is predicated upon the finding of an automatic, non-discretionary-channeling statutory aggravating circumstance.
7. Bertolotti’s right to a reliable capital-sentencing proceeding was violated when the state urged that he be sentenced to death on the basis of impermissible “victim impact” evidence.
8. Comments of the judge and the prosecutor throughout the trial impermissi-bly diminished the jury’s sense of responsibility for the awesomeness of its sentencing task.
9. Bertolotti’s conviction is void because it may have been based on a constitutionally impermissible ground, and there may not have been juror unanimity.
10. A state witness introduced impermissible evidence of Bertolotti’s propensity to crime.
11. The trial judge unconstitutionally failed to grant Bertolotti’s motion for a change of venue, and impermissibly limited Bertolotti’s ability to voir dire the jury venire.
The district court heard oral argument the morning of February 15, 1989, but declined to hold an additional evidentiary hearing on Bertolotti’s claims. Later that afternoon, the district judge denied Berto-lotti relief, and refused to issue a certificate of probable cause to appeal; the district court did however enter a twenty-four hour stay of execution to allow Bertolotti time to appeal to this court.2
II. MERITS OF THE APPEAL
Bertolotti reasserts the eleven grounds he alleged in the district court.3 We will *1509address first those claims that challenge the over-all validity of the state-court proceedings; second, those claims attacking specific errors during the guilt phase of the trial; and finally, those claims assigning constitutional error to the penalty phase of the trial.
Before turning to Bertolotti’s specific claims, we note that the district court did not abuse its discretion by declining to hold an evidentiary hearing on the one issue that we agree presents a colorable claim for relief, the ineffectiveness claim. Although such a hearing often is necessary in a first federal habeas petition, it was not here. At the four-day hearing during the state collateral proceedings, counsel for Bertolotti presented several witnesses — including all three of his trial attorneys, a psychiatrist, and an expert on criminal defense; counsel also cross-examined the witnesses produced by the state. Bertolotti thus was afforded a full and fair opportunity to develop the basis of his ineffective-assistance claim. The district court, which was provided with the 665-page transcript of that hearing, fairly concluded that another hearing would not materially aid resolution of the ineffectiveness claim. Smith v. Dugger, 840 F.2d 787, 796 (11th Cir.1988); cf. Coleman v. Zant, 708 F.2d 541, 545 (11th Cir.1983).
A. ERROR AFFECTING THE ENTIRE PROCEEDING
1. Ineffective Assistance of Trial Counsel (Claim 1)
Bertolotti’s defense was undertaken by attorneys Joseph DuRocher, Clyde Wolfe, and Peter Kenny. DuRocher, the elected public defender for the Ninth Judicial Circuit in Florida, initially interviewed Berto-lotti and assigned the case to his assistants Wolfe and Kenny. Wolfe was responsible for the guilt phase of the trial and Kenny for the penalty phase. Bertolotti argues that counsel’s performance was constitutionally defective for four reasons: (1) counsel overlooked substantial evidence of Bertolotti’s psychological problems; (2) counsel overlooked evidence of Bertolotti’s traumatic childhood; (3) counsel overlooked evidence of voluntary intoxication; and (4) counsel failed to present a defense to felony murder. Bertolotti claims that counsel’s errors prevented the presentation of an effective defense, compromising the integrity of both the guilt and penalty phases of his trial.
Our resolution of Bertolotti’s ineffectiveness claims is guided by the familiar two-prong test announced by the Supreme Court in Strickland v. Washington: to prevail, Bertolotti must first show that counsel’s performance was so deficient that “counsel was not functioning as the ‘counsel’ guaranteed the defendant by the Sixth Amendment;” second, Bertolotti must show that “counsel’s errors were so serious as to deprive [him] of a fair trial, a trial whose result is reliable.” 466 U.S. 668, 687, 104 S.Ct. 2052, 2064, 80 L.Ed.2d 674 (1984). To meet the second prong, Berto-lotti must demonstrate prejudice: “a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id., 466 U.S. at 694, 104 S.Ct. at 2068. The Strickland standard is applicable to Berto-lotti’s claims of ineffectiveness both at the guilt stage and the penalty stage of his trial. Id., 466 U.S. at 687, 104 S.Ct. at 2064.
a. Insanity and diminished capacity. —Bertolotti asserts that his trial counsel overlooked clues of mental incapacity that would have caused a reasonably competent lawyer to secure a psychiatric examination of his client. With the results that such an examination would have yielded, reasonably competent counsel could have presented insanity and diminished-capacity defenses at the guilt stage of the trial, and could have offered compelling mitigating evidence at the penalty phase of the trial. Although we conclude that Bertolotti cannot show prejudice, our resolution of the prejudice issue is determined substantially by our doubt about the strength of Berto-lotti’s evidence of psychological impairment. This doubt also colors our conclusions in regard to the performance of Ber-tolotti’s counsel. Because much of the evidence relevant to the prejudice component of the Strickland test is also relevant to the performance component on this issue, resolution of the performance component *1510will not make our task appreciably more difficult, and we voluntarily address both prongs of the Strickland test.4
(1) Attorney performance.— Nine judges already have reviewed the performance of Bertolotti’s attorneys. The unanimous Florida Supreme Court decided that counsel’s performance was deficient; the state trial judge and the district judge both concluded that counsel’s performance was adequate. Federal courts are not bound by the state determination of ineffectiveness, however (Strickland, 466 U.S. at 698, 104 S.Ct. at 2070), and it is crucial to recognize that the role of the Florida Supreme Court in deciding questions of ineffective assistance differs fundamentally from the role of the federal court. Article Five, section fifteen of the Florida Constitution provides that “The supreme court shall have exclusive jurisdiction to regulate the admission of persons to the practice of law and the discipline of persons admitted.” West’s F.S.A. Const. Art. 5, § 15 (Supp. 1989). We have no such authority: as our Supreme Court has admonished, the duty of the federal court sitting in review of a state-court proceeding “is not to grade counsel’s performance.” Strickland, 466 U.S. at 697, 104 S.Ct. at 2069. Rather, the “ultimate focus” of our inquiry “must be on the fundamental fairness of the proceeding whose result is being challenged.” Id., 466 U.S. at 696, 104 S.Ct. at 2069.
The Florida Supreme Court analyzed the performance of Bertolotti’s counsel under a state-law standard: “where there is evidence calling into question a defendant’s sanity, defense counsel is bound to seek the assistance of a mental health expert.” Bertolotti v. State, 534 So.2d at 388. Because some evidence called Bertolotti’s sanity into question and counsel failed to seek the assistance of a mental health expert until the morning of the sentencing hearing, the Florida court adjudged counsel’s performance deficient. 534 So.2d at 389. The sixth-amendment standard for deciding a claim of defective performance is not nearly this formulaic; the federal standard asks whether “counsel’s representation fell below an objective standard of reasonableness,” and “[mjore specific guidelines are not appropriate.” Strickland, 466 U.S. at 688, 104 S.Ct. at 2064. Our role in collaterally reviewing state judicial proceedings is not to point out counsel’s errors, but only to determine whether counsel’s performance in a given proceeding was so beneath prevailing professional norms5 that the attorney was not performing as “counsel” guaranteed by the sixth amendment. Strickland, 466 U.S. at 687, 104 S.Ct. at 2064. Because the question asked by the state court is not the question asked by the federal court, the fact that the two courts apparently diverge does not necessarily signal a conflict.
That counsel’s behavior transgressed a state-law duty is a factor we should consider in determining whether counsel was ineffective for the purposes of the sixth amendment, but because the sixth amendment does not guarantee perfect representation, an attorney error is not dispositive of the question of sixth-amendment ineffective assistance. Adams v. Wainwright, 709 F.2d 1443, 1446 (11th Cir.), reh. in banc den., 716 F.2d 914 (11th Cir.1983), cert. denied, 464 U.S. 1063, 104 S.Ct. 745, 79 L.Ed.2d 203 (1984). Significantly, as the state-law duty violated by Bertolotti’s counsel is not constitutionally compelled, it is less likely that Bertolotti’s representation was fundamentally flawed. The Florida court cited the United States Supreme Court’s decision in Ake v. Oklahoma, 470 U.S. 68, 105 S.Ct. 1087, 84 L.Ed.2d 53 (1985), as persuasive authority for its decision, but Ake does not require the Florida rule.
*1511The defendant in Ake behaved so strangely at arraignment and prior thereto that the trial judge, on his own motion, ordered the defendant “to be examined by a psychiatrist ‘for the purpose of advising with the Court as to his impressions of whether the Defendant may need an extended period of mental observation.’ ” 470 U.S. at 71, 105 S.Ct. at 1090. The subsequent psychiatric report revealed that the defendant appeared to be “ ‘frankly delusional.... He claims to be the “sword of vengeance” of the Lord and that he will sit at the left hand of God in heaven.’ ” Id. The psychiatrist diagnosed the defendant as a probable paranoid schizophrenic and recommended prolonged psychiatric evaluation to determine the defendant’s competency to stand trial. The defendant was committed for observation; the chief forensic psychiatrist informed the trial judge that the defendant was psychotic, schizophrenic, suffering from delusions, rage, and poor control; the trial court held the defendant incompetent to stand trial. Six weeks later, the forensic psychiatrist recommended that the defendant (by then under medication) was competent to stand trial; the state resumed proceedings. Defense counsel told the court that he planned to raise the insanity defense on behalf of his client, and he requested state funds to hire a psychiatrist for the purpose of determining whether his client was insane at the time of the offense. The trial judge refused to appropriate funds; the United States Supreme Court subsequently held that the defendant’s fourteenth-amendment rights had been violated: “We hold that when a defendant has made a preliminary showing that his sanity at the time of the offense is likely to be a significant factor at trial, the Constitution requires that a State provide access to a psychiatrist’s assistance on this issue if the defendant cannot otherwise afford one.” 470 U.S. at 74, 105 S.Ct. at 1091-92.
Ake thus speaks to the responsibility of the state when the defendant exhibits compelling evidence of incompetency or insanity, the defendant’s sanity is in issue, and the defendant is unable to afford the services of a mental-health expert. Because implicit in Ake is an assumption that counsel will recognize the applicability of the insanity defense to the facts of his particular case, counsel faced with facts comparable to those in Ake might be deficient as a matter of sixth-amendment law if he did not conduct a reasonable investigation into the possibility of raising an insanity defense. Cf Strickland, 466 U.S. at 691, 104 S.Ct. at 2066. Ake, however, does not require that counsel faced with significantly less compelling evidence of mental instability — which evidence, as in the instant case, nonetheless could call his client’s sanity into question — must move beyond a preliminary inquiry into an insanity defense and actually “seek the assistance of a mental health expert.” Cf. Bertolotti v. State, 534 So.2d at 388. As the state would not be required by the federal constitution to fund an examination under such circumstances, Moore v. Kemp, 809 F.2d 702, 712 n. 8 (11th Cir.) (in banc), cert. denied, 481 U.S. 1054, 107 S.Ct. 2192, 95 L.Ed.2d 847 (1987), counsel cannot be per se deficient for not requesting an examination. When fundamental fairness does not require that a defendant be given a benefit, fundamental fairness is not threatened by the defendant’s failure to receive that benefit if the failure is due to counsel’s reasonable decision not to request it or the court’s reasonable decision not to grant it. See generally Clark v. Dugger, 834 F.2d 1561, 1563-65 (11th Cir.1987), cert. denied, — U.S. —, 108 S.Ct. 1282, 99 L.Ed.2d 493 (1988); Bowden v. Kemp, 767 F.2d 761, 765 (11th Cir.1985).
This is not to say that vigorous counsel could never move for the appointment of an expert if he doubts that his client can make out an Ake showing; nor do we in any sense question Florida’s decision to hold its practitioners to a higher standard. Rather, the federal standard by which we measure counsel’s decision not to go forward with a full-fledged inquiry into his client’s mental health remains that announced by the Supreme Court in Strickland: “In any ineffectiveness case, a particular decision not to investigate must be directly assessed for reasonableness in all the circumstances, applying a heavy measure of deference to counsel’s judgments.” *1512Id., 466 U.S. at 691, 104 S.Ct. at 2066. In Strickland as in the instant case, the petitioner argued that his counsel was ineffective for failing to secure a psychiatric examination. Id., 466 U.S. at 675, 104 S.Ct. at 2058. Evaluating the claim, the Supreme Court held that “[t]he reasonableness of counsel’s actions may be determined or substantially influenced by the defendant’s own statements or actions.” Id., 466 U.S. at 691, 104 S.Ct. at 2066. Specifically, “when a defendant has given counsel reason to believe that pursuing certain investigations would be fruitless or even harmful, counsel’s failure to pursue those investigations may not later be challenged as unreasonable.” Id.
Turning to appraise the reasonableness of counsel’s decision not to secure a psychiatric examination until the morning of Bertolotti’s sentencing hearing,6 we view the facts “as of the time of counsel’s conduct,” recognizing that “counsel is strongly presumed to have rendered adequate assistance and made all significant decisions in the exercise of reasonable professional judgment.” Strickland, 466 U.S. at 690, 104 S.Ct. at 2066. Bertolotti’s burden is to “overcome the presumption that, under the circumstances, the challenged action ‘might be considered sound trial strategy.’ ” Id., 466 U.S. at 689, 104 S.Ct. at 2065 (quoting Michel v. Louisiana, 350 U.S. 91, 101, 76 S.Ct. 158, 164, 100 L.Ed. 83 (1955)).
Bertolotti has identified several signals that he argues should have led Kenny and Wolfe to secure a psychiatric examination prior to trial.7 A brief review of the facts surrounding the murder is needed to place the signals in context. The victim, found in *1513her house by her husband, had been repeatedly stabbed with two knives; one broke and the other was left in the body. She was naked from the waist down and forensic tests revealed that intercourse had taken place, although there was no evidence of physical trauma. The victim had also been strangled and beaten, and bore bruises that indicated she had fought back during the attack. She had been robbed of thirty dollars, and her car had been stolen. A few days later, Bertolotti was arrested after his girlfriend informed police that she suspected his involvement in the murder. He gave the police two voluntary confessions which were preserved on audio tape; in the first confession, he admitted murdering the victim, in the second, he admitted the murder and also attempted to implicate his girlfriend. See Bertolotti v. State, 476 So.2d at 131-32.
In conjunction with these facts, Bertolot-ti argues that counsel unreasonably disregarded the following signals: first, the audio tapes of his confession reveal that he was in an extremely emotional state while recounting the murder. Second, Bertolotti stated during the first taped confession that “I just, I don’t know what was happening to me.” Third, his explanation of the facts of the crime was inherently unbelievable. Fourth, Bertolotti’s girlfriend told Wolfe that she believed Bertolotti needed psychiatric help, and had a “split personality.” Fifth, Bertolotti was placed under psychiatric observation while being held for the murder. Sixth, the number of stab wounds in the victim should have indicated mental instability.
The audio tapes do indeed reveal that Bertolotti cried and moaned while explaining his crime to the police interrogators. Bertolotti’s voice is low and trembling, and as the narrative proceeds to the actual murder, Bertolotti perceptibly becomes more distraught. Throughout the entire interrogation, however, Bertolotti plainly appears to understand what he is doing, who he is talking to, and what he is talking about. His responses to the interrogator’s questions are consistently coherent. In the second taped confession, during which Ber-tolotti explains why he did not tell the full story in his first confession and also implicates his girlfriend in the wrongdoing, his tone is calm and rational. The tapes are at least as consistent with the proposition that Bertolotti was remorseful or frightened as they are with the proposition that Bertolot-ti had mental problems.
His statement that he did not “know what was happening” to him raises the possibility of mental illness, but in light of Bertolotti’s confession admitting that he knew he had killed the victim when he left the house, the statement is hardly a surefire sign of legal insanity and could simply be an effort to shirk responsibility for the crime. In the same way, the fact that a defendant offers an unbelievable explanation for his actions is hardly unusual in itself — Bertolotti first told the police interrogators that the victim invited Bertolotti into her house to use the telephone and get a drink, whereupon he attacked her with a kitchen knife; in an effort to satisfy Berto-lotti, the victim offered him jewelry and began to undress. The victim began to talk with Bertolotti and encouraged him to pray with her, but then tried to wrest the knife from him. He resisted, she screamed, and he began to stab. The first knife broke, but the victim continued to make noise and began to get up from the floor. Bertolotti found another knife and continued to stab. He then hit the victim in the head with a beer stein. In Bertolot-ti’s second confession, he told the police that he and his girlfriend entered the victim’s house in order to steal some money. The victim, who was at home, offered to have intercourse with Bertolotti in order to appease him, at which point the girlfriend became enraged. As Bertolotti and his girlfriend prepared to leave the house, the victim grabbed the girlfriend by the legs and the girlfriend ordered Bertolotti to stab the victim. Bertolotti’s stories, while incredible, are not so bizarre that counsel should immediately suspect that his client is mentally ill, “unless one were to adopt the dubious doctrine that no one in his right mind would commit a murder.” Ake, 470 U.S. at 90, 105 S.Ct. at 1100 (Rehnquist, J., dissenting).
Reasonable counsel could have discounted much of what Bertolotti’s girlfriend had *1514to say; Bertolotti attempted to implicate her in the murder, and she herself turned in Bertolotti to the police, collecting a thousand-dollar reward for her trouble. She was probably not too sympathetic to Berto-lotti’s plight, and she had her own reasons for wanting Bertolotti to appear factually responsible for the crime.
Bertolotti was placed under psychiatric observation following his arrest, but the psychologist on the sheriffs staff who ordered the observation testified that he did so as a matter of routine, in order to “follow up on anything that [he] may have missed when [he] saw” Bertolotti. Berto-lotti now states that he was placed under suicide watch on the day of his arrest. The staff psychologist did not recall placing Bertolotti under a suicide watch; instead, the psychologist was asked to interview Bertolotti after Bertolotti told a nurse questioning him about his background that on a previous occasion he had contemplated suicide. The fact that Bertolotti was placed under any type of psychological observation should have been a signal to inquire into Bertolotti’s mental state, but it does not amount to much more. Similarly, the number of stab wounds in the victim could have raised the possibility that Berto-lotti committed the murder in a frenzied rage, but in light of Bertolotti’s statement to the police that he stabbed the victim so many times because of the difficulty in accomplishing the murder, reasonable counsel need not have seized upon this evidence as a definite indicator of mental problems.
Against this evidence of mental impairment, reasonable counsel would have recognized that Bertolotti’s own actions following the murder showed that he appreciated the criminality of his conduct: he stole the victim’s car and abandoned it where it would be stolen; also, in his confession to the police, he explained how he attempted to cover up evidence of his participation in the murder. The day following the murder, moreover, Bertolotti visited a minister, telling the minister that he had problems and asking for the minister’s prayers. This evidence is important for two reasons: first, reasonable counsel could have taken this information to mean that Bertolotti was aware of the criminality of his conduct, and second, reasonable counsel would have realized that the prosecution could have used this evidence to rebut an insanity defense.
The foregoing evidence, considered as a whole, is sufficiently equivocal that reasonable counsel would not have been under a duty to secure a psychiatric examination of Bertolotti for the purpose of introducing an insanity defense or negating Bertolotti’s specific intent to commit any of the crimes with which he was charged.8 Cf. Ake, 470 U.S. at 74, 105 S.Ct. at 1091-92. The foregoing, however, probably suggested the need for some further inquiry into Berto-lotti’s mental state. The record indicates that counsel did make preliminary inquiries into Bertolotti’s mental condition, but then abandoned the effort. As this decision was made “after less than complete investigation” of Bertolotti’s mental health, Strickland requires an assessment whether “reasonable professional judgments supported] the limitations on investigation.” Id., 466 U.S. at 691, 104 S.Ct. at 2066.
Recalling that “[t]he reasonableness of counsel’s actions may be determined or substantially influenced by the defendant’s own statements or actions,” 466 U.S. at 691, 104 S.Ct. at 2066, we find it dispositive that both Bertolotti and his parents informed counsel that Bertolotti had never experienced any previous mental problems; Bertolotti’s parents also told counsel that Bertolotti was of above-average intelligence. See Daugherty v. Dugger, 839 F.2d 1426, 1431 (11th Cir.), reh. in banc den., 845 F.2d 1032 (11th Cir.), cert. denied, — *1515U.S. —, 109 S.Ct. 187, 102 L.Ed.2d 156 (1988); cf. Elledge v. Dugger, 828 F.2d 1439, 1445 (11th Cir.) (counsel defective for mounting psychiatric defense yet failing to interview relatives or seek expert assistance), mod. on other grounds and reh. in banc den., 833 F.2d 250 (11th Cir.1987), cert. denied, — U.S. —, 108 S.Ct. 1487, 99 L.Ed.2d 715 (1988). Counsel did not have any reason to think that Bertolotti was less than forthcoming; counsel testified that he interviewed Bertolotti numerous times, found Bertolotti communicative and appropriately behaved, and was “very comfortable with Mr. Bertolotti.” Cf. Thompson v. Wainwright, 787 F.2d 1447, 1451 (11th Cir.) (counsel testified that he thought client was retarded), reh. in banc den., 792 F.2d 1126 (11th Cir.1986), cert. denied, 481 U.S. 1042, 107 S.Ct. 1986, 95 L.Ed.2d 825 (1987). Furthermore, counsel spoke with a staff psychologist at a facility where Bertolotti previously had been incarcerated, who indicated that Bertolotti had adjusted well to the prison setting, served as a peer-counselor, and was in fact so trusted by the prison authorities that he was allowed access to scissors and razors so he could work as a barber. Further inquiry would have revealed that this same psychologist had at one point thought that Bertolotti exhibited “indications of the possibility of disorganization under stress, cyclic bizarre and/or aggressive behavior and sexual dysfunction,” but the psychologist did not volunteer this information and counsel was not aware of it. Although it is difficult to recreate the circumstances of the interview, counsel’s failure to ask this psychologist specifically whether he had noticed any mental problems in Bertolotti might be considered unreasonable. See Thompson, 787 F.2d at 1451 n. 2. The failure was likely harmless in any event: the psychologist concluded that “[a]ll of these indications have now disappeared, and it is likely that [Bertolotti] will do well in a work release setting. However, it should be noted that persons with [socio-pathic] profiles similar to [Bertolotti’s] present one, have extremely high recidivism rates, usually for crimes of a property offense nature.” Even this information would have been an equivocal indicator of insanity at the time of the murder of Carol Ward.
In short, counsel testified that “[w]e had done a great deal of investigation and deposition work as to the events prior to the offense and afterwards, and those matters did not trigger an insanity defense for me.... An insanity defense would have seemed to me inconsistent with the facts that would ... otherwise have been presented at trial.” On the basis of counsel’s inquiry and the evidence that Bertolot-ti appreciated the wrongfulness of his conduct, we cannot say that counsel behaved unreasonably in not securing a psychiatric examination for the purpose of introducing an insanity defense or for the purpose of negating premeditation. Stephens v. Kemp, 846 F.2d 642, 653 (11th Cir.) (no further duty of inquiry for purposes of guilt phase of trial when preliminary investigation of psychiatric evidence reveals that petitioner was hospitalized for psychiatric problem between four and six months prior to crime, but psychiatric report indicates no evidence of severe mental illness), reh. in banc den., 849 F.2d 1480 (11th Cir.), cert. denied, — U.S. —, 109 S.Ct. 189, 102 L.Ed.2d 158 (1988). As the state judge orally concluded after the evidentiary hearing in the collateral proceedings, counsel “attempted to save the life of their client by realistically arguing that this was a second-degree murder rather than a first-degree murder and opted not to take the unrealistic approach of not guilty by reason of insanity.” Under the circumstances, the decision of Bertolotti’s counsel can be considered sound trial strategy.9
Even though the totality of the evidence discouraged counsel from mounting a psychologically based defense to the substantive crimes, evidence of mental impairment could still have been used during *1516the sentencing phase of the trial. See Stephens, 846 F.2d at 653 (greater duty of inquiry into client’s mental health imposed for penalty phase of trial). Because of the evidence that Bertolotti appreciated the wrongfulness of his acts, of course, counsel could still quite reasonably have entertained serious doubt about the efficacy of such evidence at the sentencing phase; nonetheless, counsel may have been able to evoke the jurors’ sympathy or rebut some of the state’s aggravating evidence with testimony that Bertolotti suffered psychological problems. Counsel attempted to have Bertolotti interviewed by a psychiatrist on the morning of the sentencing hearing, but Bertolotti refused to be seen. With a total lack of evidence that Bertolotti was not a competent decision-maker on the morning of the sentencing hearing, we cannot say that counsel behaved unreasonably by not taking further steps to encourage Bertolotti to undergo an examination. Cf. Faretta v. California, 422 U.S. 806, 820, 95 S.Ct. 2525, 2533, 45 L.Ed.2d 562 (1975) (recognizing a right to pro se representation: the “language and the spirit of the Sixth Amendment contemplate that counsel, like the other defense tools guaranteed by the Amendment, shall be an aid to a willing defendant — not an organ of the State interposed between an unwilling defendant and his right to defend himself personally”); Foster v. Strickland, 707 F.2d 1339, 1343 (11th Cir.1983) (lawyer bound by client’s decision against insanity defense), cert. denied, 466 U.S. 993, 104 S.Ct. 2375, 80 L.Ed.2d 847 (1984); American Bar Association Model Code of Professional Responsibility EC 7-7 & 7-8.
(2) Prejudice. — To demonstrate prejudice, Bertolotti relies largely on the testimony of Dr. James R. Merikangas, a psychiatrist who prior to the state evidentiary hearing interviewed Bertolotti for one hour and fifteen minutes, spoke with members of Bertolotti’s family, and reviewed documents relating to Bertolotti’s case. Dr. Merikangas testified that Bertolotti was insane at the time he murdered Carol Miller Ward. Bertolotti argues that had Dr. Merikangas’s testimony been presented to the jury, there is a reasonable probability that the jury would have acquitted him on grounds of insanity. Even had the jury not acquitted him, there is a reasonable probability that Dr. Merikangas’s testimony would have saved Bertolotti from the electric chair, because the jury may have found Bertolotti guilty only of second-degree murder, or may have found during the penalty phase of the trial that mitigating circumstances outweighed the aggravating circumstances.
Dr. Merikangas opined that Bertolotti was a schizophrenic who had a catastrophic reaction to the stress he experienced while hearing the victim scream. He reacted by stabbing the victim repeatedly, and while he was in the process of killing her, he was unable to discern right from wrong. Dr. Merikangas relied upon several factors to conclude that Bertolotti was schizophrenic. Bertolotti’s mother briefly had been committed to a psychiatric hospital for schizophrenia in the late nineteen-sixties. Berto-lotti suffered from delusions, did not exhibit appropriate reactions, and was “religiously confused.” He had been reared in an overly strict and overly religious household, and was subjected to “psychological abuse” by his father; he would tell lies for self-aggrandizement or to accept the blame for wrongs he had not done, would cry easily, and did poorly in school despite possessing above-average intelligence. He never had a girlfriend, and he used several aliases.
Dr. Merikangas explained the basis of his opinion on the catastrophic-stress reaction as follows:
I believe my opinion is that [Bertolotti] is a schizophrenic who had a catastrophic reaction to stress, that people with this disorder are predisposed to break down under conditions of stress and go berserk, as this man apparently did; and that this is borne out not only by his recounting of the crime and the several different versions which he used, but by the facts that are documented in the autopsy and the police report of a berserk rage, stabbing multiple times with two different knives, for instance; his actions after the crime of leaving bloodstains all around and leaving the weapon there and going home and hiding these *1517clothes; his girlfriend, who is not a trained psychologist, observing that there was something weird and strange about him; his blubbering and whining and decompensating while giving a voluntary confession to the police the first time, and then coming back with another different confession that tried to implicate his girlfriend after he had time to consider it and calm down; and his past history all point to the same conclusion.
Dr. Merikangas’s testimony is vulnerable to well-considered attack on several fronts and we doubt that a jury would find it convincing.
All psychiatrists and psychologists who testified at the evidentiary hearing agreed that schizophrenia can be hereditary; therefore, that Bertolotti’s mother was once hospitalized with the illness is probative of the proposition that Bertolotti possibly suffers from the same illness. Beyond this evidence of schizophrenia, however, the evidence Dr. Merikangas relied upon in formulating his views is extremely weak. Bertolotti’s alleged delusions, for example, consist chiefly of his belief that he could control those around him and influence the outcome of the evidentiary hearing. Dr. Merikangas was not aware of these delusions when he was deposed by attorneys for the state shortly before the evidentiary hearing; Bertolotti’s attorney informed someone in his office who in turn told Dr. Merikangas that Bertolotti had related the delusions to counsel sometime between the deposition and the hearing. Even though Dr. Merikangas’s opinion is not necessarily inadmissible because he relies on rather questionable hearsay testimony in formulating his belief, see Fed.R. Evid. 703, the trustworthiness of the basis for Dr. Merikangas’s opinion is certainly something for the court to consider in deciding whether a fact-finder would credit the testimony. Elledge v. Dugger, 823 F.2d 1439, 1447 (11th Cir.1987) (value of doctor’s testimony undercut by doctor’s reliance on uncorroborated facts). The remaining factors Dr. Merikangas relied upon in concluding that Bertolotti suffered from delusions are unexceptional; these involved Bertolotti’s use of aliases and his lying, evidenced in various prison records, about his own employment history, his father’s employment, his mother’s educational background, and the size of his family.
Bertolotti’s alleged inappropriate reactions are also the subject of some dispute. Although Dr. Merikangas’s testimony indicates that Bertolotti was displaying inappropriate responses during the evidentiary hearing, this behavior seems contradictory to the behavior evidenced on the taped confession, and the behavior otherwise testified to by trial counsel, the interrogating police officer, and a psychiatrist who interviewed Bertolotti for the state. The sheriff’s staff psychologist did make the notation “flat affect” while interviewing Berto-lotti after his arrest, which would indicate that Bertolotti showed little or no emotion during the interview, but the psychologist testified that Bertolotti’s reaction was not atypical. As to Bertolotti’s “religious confusion,” he apparently could not decide whether he wanted to be Catholic or Jewish, but, as Dr. Merikangas agreed, it is not unusual for people placed in jail to reassess their basic religious beliefs.
Regarding the severity of the home in which Bertolotti was reared, there is no strong evidence that Bertolotti was physically abused, and Dr. Merikangas did not place much emphasis on such evidence in forming his opinion. Instead, Dr. Merikan-gas testified that “spanking a child when he needs it” can be considered “psychological abuse.” Dr. Merikangas’s view that the home was overly strict is based on information that Bertolotti’s “father and ... mother would look under the bed to see if there [was] any dust before the children would be allowed to go out and play.” Further, Dr. Merikangas was told that Ber-tolotti and his siblings were locked out of the house during the day so they could not sully the interior. As to Dr. Merikangas’s charge that the household was “overly religious,” the testimony merely shows that the children were taken to long church services on Sundays, and the father subscribed to the maxim that spared rods spoil children. The remaining bases for Dr. Merikangas’s diagnosis of schizophrenia— that Bertolotti was an underachiever and unpopular with girls — eoncededly are consistent with a wide variety of problems.
*1518Dr. Merikangas opined that Bertolotti was unable to discern between right and wrong at the time of the murder because of his catastrophic reaction to stress. A forensic psychologist called by the state (who had not interviewed Bertolotti personally but who appears, upon the cold record, to be the least partisan witness at the hearing) had trouble with the notion that the victim’s screaming could have precipitated Bertolotti’s reaction:
It’s also hard for me to put [the victim’s screaming] into a [catastrophic-stress] model in view of the total situation that was going on. There was obviously an attack involved and normally when people are attacked, they make some kind of audible as well as physical response to it. So one would expect potentially, if you go after someone, they’re probably going to scream. And to see that as a catastrophic stresser is very difficult because we would tend to see that as an expected event.
The factors identified by Dr. Merikangas as consistent with his belief that Bertolotti had suffered a catastrophic reaction to stress are likewise consistent with the proposition that Bertolotti stabbed the victim repeatedly because of the difficulty in killing her, tried to hide his blood-stained clothes so he would not be detected, experienced remorse while recounting the crime, and later, upon reflection (tempered by anger that his girlfriend had betrayed him) attempted to implicate the girlfriend in the murder.10
Bertolotti’s counsel put the same question to each of the state’s three mental-health experts: counsel asked the experts whether their disagreement with Dr. Meri-kangas’s testimony necessarily meant that Dr. Merikangas was wrong, and if not whether they agreed that because psychiatry and psychology are “arts, not sciences,” reasonable professionals could differ in their diagnoses. Each of the state’s witnesses agreed with the latter proposition; indeed, it is unexceptional to anyone with a modest amount of trial experience. Partisan psychologists and psychiatrists will often disagree in courts of law. Before we are convinced of a reasonable probability that a jury’s verdict would have been swayed by the testimony of a mental-health professional, we must look beyond the professional’s opinion, rendered in the impressive language of the discipline, to the facts upon which the opinion is based. Elledge, 823 F.2d at 1447.
In the instant case, we are not convinced that there is a reasonable probability that Dr. Merikangas’s testimony would have had an effect on the jury’s verdict of first-degree murder.11 The testimony itself is *1519internally weak, and it would have been directly rebutted by similarly qualified experts. Elledge, 823 F.2d at 1447. We doubt that a jury would have acquitted Bertolotti on grounds of insanity. Bundy v. Dugger, 850 F.2d 1402, 1412 (11th Cir.), reh. in banc den., 859 F.2d 928 (11th Cir.1988), cert. denied, — U.S. —, 109 S.Ct. 849,102 L.Ed.2d 980 (1989). We also doubt the existence of a reasonable probability that the jury would have convicted Bertolotti of a lesser-included, non-capital offense on the basis of Dr. Merikangas’s testimony. Dr. Merikangas did testify that Bertolotti was capable of forming the intent to rob the victim, and in fact he had “no question that [Bertolotti] had the desire to rob Carol Ward.” Therefore, even if the psychiatrist’s testimony would have supported the inference of diminished capacity, precluding a probable conviction of premeditated murder, Dr. Merikangas’s testimony would not have changed a verdict of felony murder, which is also death-eligible under Florida law.
Turning to the sentencing phase of Bertolotti’s trial, we see no reasonable probability that the evidence discussed above would have resulted in a life sentence for Bertolotti.12 Because the evidence of psychological impairment would have been strongly disputed by the state’s expert witnesses, and because the evidence itself has substantial internal weaknesses, we question whether counsel would have presented the evidence to the jury even had counsel possessed it. Attorney Kenny testified that his penalty-phase tactical theory was to portray Bertolotti as a normal man from a happy and loving family, whose life deserved to be spared; in light of the weakness of Bertolotti’s psychiatric evidence, this tack would continue to be a reasonable strategy.
Assuming counsel would have produced the evidence, however, we nonetheless agree with the district court’s factual conclusion that a jury likely would have found the state’s expert testimony more logical and credible than the testimony offered in Bertolotti’s behalf;13 at most, the experts from opposing camps would have offset one another.14 Bundy, 850 F.2d at 1409, 1412; Daugherty, 839 F.2d at 1431; El-ledge, 823 F.2d at 1447-48. Moreover, in view of the three statutory aggravating circumstances presented to the jury — a disturbing record of prior criminal convictions, three felonies accompanying the victim’s murder, and the especial heinousness, atrocity and cruelty of the murder — Berto-lotti has not established a reasonable probability that equivocal evidence of mental instability would have tipped the jury’s weighing of aggravating and mitigating circumstances in his favor. Thompson, 787 F.2d at 1453 (no reasonable probability that evidence of troubled youth, unsavory codefendant, and mental incapacity would have altered jury’s recommendation of death sentence for brutal torture-murder); Elledge, 823 F.2d at 1447. Even if the proffered evidence would have affected the jury’s consideration of the third aggravating circumstance, the other two would remain amply supported. Cf. Ford v. Strickland, 696 F.2d 804, 815 (11th Cir.) (in banc) *1520(resentencing not necessarily required when one aggravating circumstance is struck on appellate review), cert. denied, 464 U.S. 865, 104 S.Ct. 201, 78 L.Ed.2d 176 (1983).
b. Remaining grounds of ineffective assistance.—We may quickly dispose of Bertolotti’s remaining charges of ineffective assistance of counsel. Testimony at the evidentiary hearing showed that counsel conducted a reasonable investigation into the circumstances of Bertolotti’s childhood; counsel interviewed Bertolotti’s parents personally and also had them complete a lengthy questionnaire concerning Bertolotti’s past experiences.
The evidence does not show that counsel unreasonably failed to raise a voluntary-intoxication defense to the specific-intent crimes of murder, robbery and burglary. The Florida Supreme Court held that the evidence of intoxication was insufficient to warrant a voluntary-intoxication instruction. Bertolotti v. State, 534 So.2d at 387. Bertolotti does not now show that counsel overlooked any other evidence of intoxication; indeed, Bertolotti later claimed that he had lied when he told police officers that he was under the influence of a quaalude at the time of the murder.
Nor does Bertolotti’s final ineffectiveness claim have merit. Bertolotti argues that counsel simply did not grasp the fact that felony murder, like premeditated murder, is death-eligible under Florida law; as a consequence, Bertolotti argues that counsel failed to mount a defense against felony murder. During a hearing on several pending pre-trial motions, however, Attorney Wolfe informed the court that the state could prove capital murder by proving felony murder. Furthermore, the record shows that counsel sought to raise a reasonable doubt whether Bertolotti had committed the three charged predicate felonies. Bertolotti has shown neither attorney error nor prejudice.
2. Caldwell Violations Occurring Throughout the State Proceedings (Claim 8)
Bertolotti argues that the prosecutor and judge impermissibly diminished the jury’s sense of responsibility for the awesomeness of its task, in violation of Caldwell v. Mississippi, 472 U.S. 320, 105 S.Ct. 2633, 86 L.Ed.2d 231 (1985). The Florida Supreme Court found this claim procedurally barred because it was not raised on direct appeal; alternatively, the Florida court refused to address the merits of Ber-tolotti’s Caldwell claim because Florida maintains that Caldwell is inapplicable to its statutory scheme, in which the trial judge imposes the death sentence. Bertolotti v. State, 534 So.2d at 387 n. 2.
Although we question the strength of Bertolotti’s claim,15 the doctrine of procedural bar prevents us from addressing the merits. In Dugger v. Adams, the Supreme Court recently held that Florida petitioners generally do not have cause for failing to object to Caldwell-type errors during pre-Caldwell trials, because Florida has long recognized that a defendant must object if the judge misinstructs jurors on applicable state law. — U.S. —, 109 S.Ct. 1211, 1215-16,103 L.Ed.2d 435 (1989). Similarly, Florida has long held that the defense must object to improper prosecutorial remarks. E.g., Rogers v. State, 158 Fla. 582, 30 So.2d 625, 628-29 (1947). As Bertolotti suggests no other manner of satisfying the cause- and-prejudice test of Wainwright v. Sykes, 433 U.S. 72, 97 S.Ct. 2497, 53 L.Ed.2d 594 (1977), we conclude that Florida’s decision constitutes an adequate and independent ground for decision.
3. Improper Denial of Motion for a Change of Venue and Improper Limitation of Bertolotti’s Right to Voir Dire the Jury Venire (Claim U)
News stories about the murder of Carol Miller Ward were carried on television and printed in the newspapers following discovery of the crime and following Bertolot-*1521ti’s arrest and confession; a local television station also carried a report on Bertolotti’s impending trial shortly before jury selection began. Prior to jury selection, counsel moved for a change of venue and for individual voir dire. At a hearing on March 19, 1984, the trial judge granted Bertolotti’s motion for individual voir dire,16 but, concluding that Bertolotti had not demonstrated prejudice, denied the motion for change of venue. The judge informed defense counsel that should difficulty in obtaining an impartial jury “appear to be the case during voir dire, ... you are entitled to raise the issue at that time.” On March 26, prior to voir dire, counsel renewed the motion for a change of venue. At a subsequent hearing in open court, the trial judge reviewed video tapes of televised news reports that aired in September and October 1983 and March 1984, but again denied Bertolotti’s motion for a change of venue without prejudice to reconsider should voir dire show that the venire was biased. Jury selection began later that day.
Of fifty prospective jurors called, individual voir dire revealed that thirteen were sufficiently biased to be excused for cause; of that number, six were excused because of a preconceived notion of Bertolotti’s guilt. In response to questions posed by the judge and by the attorneys, the remaining thirty-seven jurors indicated that they could determine Bertolotti’s guilt or innocence based upon the evidence adduced at trial and not upon any preconception. The attorneys selected a panel of twelve jurors and two alternate jurors; of this number, three had no knowledge of the murder, nine had some knowledge of the murder, and two knew of the existence of Bertolot-ti’s confession. Counsel did not move for a change of venue after voir dire commenced.
The individual voir dire conducted by Bertolotti’s lawyers insured that Bertolotti was tried by an impartial jury under the sixth and fourteenth amendments; accordingly, Bertolotti has not demonstrated that he was actually prejudiced by the trial judge’s denial of his motion for a change of venue. Importantly, if jurors can lay aside preconceptions and base their verdict on the evidence adduced at trial, they need not be completely unaware of the facts of a given case. Murphy v. Florida, 421 U.S. 794, 799-800, 95 S.Ct. 2031, 2036, 44 L.Ed.2d 589 (1975). Perhaps recognizing the difficulty in proving actual prejudice on the basis of the voir dire transcript, Bertolotti submits that his case “is of that rare breed which does exceed the extremely high threshold test of presumed prejudice requiring a change of venue.” Coleman v. Kemp, 778 F.2d 1487, 1489 (11th Cir.1985), reh. in banc den., 782 F.2d 896 (11th Cir.), cert. denied, 476 U.S. 1164, 106 S.Ct. 2289, 90 L.Ed.2d 730 (1986). We disagree.
The record contains two news articles that appeared in the Orlando Sentinel in October of 1983, five months before the trial. The articles, one of which appeared on the front page of the Sentinel, detail facts surrounding the murder and Bertolot-ti’s subsequent arrest, and also recount Bertolotti’s prior criminal record. Beyond this evidence, the record contains affidavits of Bertolotti and two public defenders in which the affiants state that “extensive publicity” surrounded the murder investigation. The record does not contain the video tapes viewed by the trial judge; the judge indicated, however, that the tapes contained references to statements attributed to Bertolotti. The record is devoid of circulation figures for the newspaper and audience-share figures for the televised newscasts.
This showing is plainly inadequate to establish a claim of presumed prejudice under our decisions.17 In Bundy, the petitioner *1522produced much more evidence of pretrial publicity than Bertolotti now presents. 850 F.2d at 1425. Six months prior to jury selection in the proceeding under attack in Bundy, a public television station had broadcast half-hour summaries of another of the defendant’s trials; the commercial television stations likewise provided extensive coverage of the earlier trial and the defendant also presented several newspaper accounts from the local newspaper. As in the instant case, the articles and broadcasts were factual in nature and did not include editorial commentary on the defendant’s guilt. An opinion poll suggested that ninety-eight percent of the county residents were familiar with the name “Bun-dy,” fifty-eight percent knew that the defendant had been involved in the earlier case, and thirty-one percent believed that the defendant’s earlier conviction strongly indicated that he was guilty in the case under collateral attack. We rejected this evidence, noting that “prejudice is not presumed simply because the defendant’s criminal record is well publicized.” Id., 850 F.2d at 1425 (citing Murphy v. Florida). Following our decision in Bundy, we conclude that Bertolotti has not shown that he was constitutionally entitled to a change of venue. See also Cummings v. Dugger, 862 F.2d 1504, 1511-12 (11th Cir.), cert. denied, — U.S. —, 109 S.Ct. 3169, 104 L.Ed.2d 1031 (1989); Marsden v. Moore, 847 F.2d 1536, 1543 (11th Cir.), cert. denied, — U.S. —, 109 S.Ct. 534, 102 L.Ed.2d 566 (1988).
B. ERROR AT THE GUILT PHASE
1. The Verdict of Guilty (Claim 9)
Bertolotti argues that the verdict of guilty may have been based on an impermissible ground and thus must be reversed. This claim is styled both as a claim on the merits, and as a claim asserting ineffective assistance of appellate counsel. See Evitts v. Lucey, 469 U.S. 387, 396, 105 S.Ct. 830, 836, 83 L.Ed.2d 821 (1985) (defendant entitled to effective assistance of counsel on as-of-right appeal). Because appellate counsel failed to raise this claim on Bertolotti’s direct appeal, the Florida Supreme Court imposed a procedural bar. Bertolotti v. Dugger, 514 So.2d at 1096. The Florida court reached the merits of the ineffectiveness claim, holding that appellate counsel was not incompetent for failing to raise the claim on direct appeal, because trial counsel had failed to preserve the claim at trial; essentially, appellate counsel was not ineffective because trial counsel’s error barred the claim. Id. at 1097.
This is not the case of a meritorious claim hung in a procedural tangle. Berto-lotti argues that insufficient evidence was adduced to convict him of sexual battery and burglary, and that therefore, a verdict of felony murder must be void because it may have been predicated upon either of those two felonies. Bertolotti’s basis for this claim is the following statement in the trial court’s sentencing order:
The capital felony was committed while the Defendant was engaged, ... in the commission of a robbery. The Defendant in his voluntary statement admitted that he robbed the victim of approximately thirty dollars at knifepoint. There is strong evidence that the capital crime was committed while the Defendant was also engaged in a burglary and rape, but those factors were not proven beyond every reasonable doubt. Aggravating factor found as to robbery only.
(Emphasis in original). The trial judge did not, by this finding, hold that the state produced insufficient evidence to convict Bertolotti of the substantive crimes of burglary or sexual abuse. Rather, the trial judge decided that he would not take the crimes into consideration as aggravating factors justifying imposition of the death penalty. As the judge stated, “strong evidence” did support the state’s allegation *1523that Bertolotti committed burglary and sexual abuse: the state offered testimony that the victim was afraid of strangers and would not likely have invited a stranger into the home; the victim’s body was discovered partially nude, and exhibited signs of sexual intercourse. Although a lawyer might argue that the trial judge’s use of the term “reasonable doubt” signified that the state had not produced sufficient evidence to convict the defendant, when the term is considered in context it is clear that the judge did not intend to make an insufficiency finding applicable to the guilt phase of the trial. Bertolotti’s claim on the merits is quite tenuous; counsel clearly cannot be held ineffective for deciding not to advance the claim on appeal.
2. Unanimity of the Verdict (Claim 9)
The jury returned a general verdict of guilty upon a charge of premeditated murder and felony murder. Bertolotti argues that even if all the jurors agreed that he was guilty, they may not have agreed on a theory of guilt: thus, six jurors may have thought that Bertolotti was guilty of felony murder but not premeditated murder, and vice versa. The Florida Supreme Court found this claim to be procedurally barred because “trial counsel made no request for a special verdict, nor did he object to the use of the general verdict form.” Bertolotti v. Dugger, 514 So.2d at 1097. Assuming that this claim arises under the fourteenth amendment, we respect Florida’s adequate and independent ground of decision; additionally, because the claim was procedurally barred, appellate counsel cannot be faulted for declining to raise it on direct appeal. Francois v. Wainwright, 741 F.2d 1275, 1285 (11th Cir.1984).
3. Evidence of Bertolotti’s Propensity to Crime (Claim 10)
Bertolotti characterizes this as a claim affecting the reliability of his sentencing, but it is clear that evidence of certain prior criminal activity is admissible during the sentencing phase of a capital trial. Fla. Stat. Ann. § 921.141(5)(b); Zant v. Stephens, 462 U.S. 862, 886, 103 S.Ct. 2733, 2747, 77 L.Ed.2d 235 (1983). We will thus consider whether this claim has merit in the context of the guilt phase of Berto-lotti’s trial. During direct examination, Bertolotti’s girlfriend, a prosecution witness, testified as follows:
I just about had him talked into going [to the police] with me, and he asked me if he could have one more day of freedom because he knew he was going to prison again....
Defense counsel immediately moved for a mistrial, which the judge denied; the prosecutor explained that the statement was inadvertent and that the witness had been warned not to mention Bertolotti’s criminal record. The prosecutor indicated that he would not oppose a cautionary instruction; defense counsel objected, arguing that a cautionary instruction would do more harm than good. The trial judge acceded to the defense request. The error was harmless beyond any reasonable doubt in light of the overpowering evidence of guilt adduced in this case; we doubt there is any possibility that the jury would have been less prone to convict Bertolotti had they not suspected him of earlier criminal involvement.
C. ERROR AT THE PENALTY PHASE
1. The Prosecutor’s Penalty-Phase Argument (Claim 2)
During the sentencing phase of Bertolotti’s trial, the prosecutor argued to the jury as follows:
And he says he didn’t rape her.... But the evidence would show otherwise. And here she is found nude from the waist down, her underwear and pants and shoes on the floor of the kitchen. And what does that tell you? The man raped her. And yet he comes in here with the audacity to tell us, “I didn’t have sex with her.”
The Florida Supreme Court decided that this remark was “ ‘fairly susceptible’ of being interpreted as a comment on the defendant’s exercise of his right to remain silent,” and as such was improper. Bertolotti v. State, 476 So.2d at 132-33. Nevertheless, the Florida court determined that the comment was not “so outrageous as to taint the validity of the jury’s recommenda*1524tion in light of the evidence of aggravation presented.” Id., 476 So.2d at 133. Berto-lotti strenuously urges that the decision of the Florida court is a “factual finding” that his fifth-amendment rights were violated, binding on a federal habeas court to the extent stated in 28 U.S.C. § 2254(d). We disagree; the Florida decision is a non-binding opinion on a mixed question of law and fact. See Cuyler v. Sullivan, 446 U.S. 335, 341-42, 100 S.Ct. 1708, 1714-15, 64 L.Ed.2d 333 (1980). Although the prosecutor’s comment may have been improper under Florida law, it was not a violation of Bertolotti’s fifth-amendment right to remain silent.
Our test for determining whether the prosecutor’s comments infringed the fifth-amendment right to silence is to ask “whether the statement was manifestly intended or was of such character that a jury would naturally and necessarily take it to be a comment on the failure of the accused to testify.” Hall v. Wainwright, 733 F.2d 766, 772-73 (11th Cir.) (quoting United States v. Vera, 701 F.2d 1349, 1362 (11th Cir.1983) and United States v. Dearden, 546 F.2d 622, 625 (5th Cir.),18 cert. denied, 434 U.S. 902, 98 S.Ct. 295, 54 L.Ed.2d 188 (1977)), reh. in banc den., 749 F.2d 733 (11th Cir.1984), cert. denied, 471 U.S. 1107, 105 S.Ct. 2344, 85 L.Ed.2d 858 (1985). The reviewing court must “look to the context in which the statement was made in order to determine the manifest intention which prompted it and its natural and necessary impact upon the jury.” Hall, 733 F.2d at 773 (quoting Samuels v. United States, 398 F.2d 964, 967 (5th Cir.1968), cert. denied, 393 U.S. 1021, 89 S.Ct. 630, 21 L.Ed.2d 566 (1969)).
Bertolotti’s explanation of the circumstances in which the victim was found was provided to the jury through his taped confessions. Review of the prosecutor’s closing argument shows that the attorney’s intent was to argue a point in the evidence, not to comment on the fact that Bertolotti declined to take the stand. Nor do we think the jurors would have understood the prosecutor’s remarks as a surreptitious comment on Bertolotti’s failure to testify; the jury most likely took the comment as an exhortation to conclude from all the evidence admitted that Bertolotti had sexually abused his victim. The comment was within the bounds of reasonable prosecuto-rial argument, and did not “so infect[ ] the trial with unfairness as to make the resulting conviction a denial of due process.” Donnelly v. DeChristoforo, 416 U.S. 637, 643, 94 S.Ct. 1868, 1871, 40 L.Ed.2d 431 (1974).19
2. Shifting the Burden of Proof (Claim 4)
Bertolotti argues that the jury was instructed to presume that a sentence of death was the appropriate penalty in his case unless the defense proved otherwise. See Jackson v. Dugger, 837 F.2d 1469, 1474 (11th Cir.), reh. in banc den., 842 F.2d 339 (11th Cir.), cert. denied, — U.S. —, 108 S.Ct. 2005, 100 L.Ed.2d 236 (1988). Review of the jury instructions shows that this was manifestly not the case. The trial judge properly fulfilled his constitutional duty of explaining to the jury the function of miti*1525gating and aggravating circumstances. See Peek v. Kemp, 784 F.2d 1479, 1494 (11th Cir.) (in banc), cert. denied, 479 U.S. 939, 107 S.Ct. 421, 93 L.Ed.2d 371 (1986).
The judge instructed the jury as follows: [I]t is your duty to follow the law that will now be given you by the court and render to the court an advisory sentence based upon your determination as to whether sufficient aggravating circumstances exist to justify the imposition of the death penalty and whether sufficient mitigating circumstances exist to outweigh any aggravating circumstances found to exist.
The judge then explained Florida’s statutory aggravating circumstances to the jury. Following the explanation, the judge instructed the jurors:
If you find the aggravating circumstances do not justify the death penalty, then your advisory sentence should be one of life imprisonment without possibility of parole for twenty-five years.
Should you find sufficient aggravating circumstances do exist, it will then be your duty to determine whether mitigating circumstances exist that outweigh the aggravating circumstances.
The judge next explained the mitigating circumstances, concluding by informing the jury that it could consider in mitigation “[a]ny other aspect of the defendant’s character or record and any other circumstance of the offense.” The judge further cautioned the jury that any aggravating circumstance must be established beyond a reasonable doubt, but that mitigating circumstances need not be so established. If the jury found an aggravating circumstance, it was to “then consider all of the evidence tending to establish one or more mitigating circumstances and give that evidence such weight as you feel it should receive in reaching your conclusion as to the sentence that should be imposed.”
The jury was not instructed that it should presume death to be the appropriate penalty once an aggravating circumstance was established. Cf. Adamson v. Ricketts, 865 F.2d 1011, 1041-44 (9th Cir.1988) (in bane) (Arizona capital statute unconstitutional because it required defendant to establish the existence of a mitigating circumstance once an aggravating circumstance had been established, and defendant bore risk of non-persuasion that mitigating circumstances outweighed aggravating circumstances); Jackson, 837 F.2d at 1473 (jury instructed that “death is presumed to be the proper sentence” unless aggravating factors are “overridden” by mitigating factors). Rather, Bertolotti’s jury was instructed that it must find an aggravating circumstance beyond a reasonable doubt before it need consider mitigating circumstances, and even then it need not look for mitigating circumstances if it found that the “aggravating circumstances do not justify the death penalty.” If the jury did find that the aggravating circumstances justified the death penalty, it was to determine whether any other aspect of Bertolot-ti’s record or character or offense stood in mitigation of his crime. This set of instructions adequately described the plan of Florida’s capital-sentencing statute, see Proffitt v. Florida, 428 U.S. 242, 248-51, 96 S.Ct. 2960, 2965-66, 49 L.Ed.2d 913 (1976) (plurality opinion of Stewart, Powell & Stevens, JJ.), quite reasonably focused the jury’s attention on the circumstances of the offense and the character of the offender, and adequately bridled the jury’s discretion. Woodson v. North Carolina, 428 U.S. 280, 304, 96 S.Ct. 2978, 2991, 49 L.Ed.2d 944 (1976) (plurality opinion of Stewart, Powell & Stevens, JJ.).20
3. Jury Instruction Concerning Mercy (Claim 3)
Bertolotti requested the following jury instruction:
The Death Penalty is warranted only for the most aggravated and unmitigated of crimes. The law does not require that death be imposed in every conviction in which a particular set of facts occur. Thus, even though the factual circumstances may justify the sentence of death *1526by electrocution, this does not prevent you from exercising your reasoned judgment and recommending life imprisonment without eligibility for parole for twenty-five years.
The trial judge denied this instruction, and the Florida Supreme Court affirmed, holding that the instruction was subsumed within the standard jury charge given by the trial judge. Bertolotti v. State, 476 So.2d at 132. In Proffitt v. Wainwright, we noted that the Constitution did not mandate an instruction explicitly authorizing the jury to disregard the trial evidence and to exercise its power of mercy. 756 F.2d 1500, 1504 n. 5 (11th Cir.), reh. in banc den., 774 F.2d 1179 (11th Cir.1985).21 What our cases require is that the trial court correctly explain the function of aggravating and mitigating circumstances under state law. Peek, 784 F.2d at 1494. As we concluded supra Part II.C.2, the trial judge’s explanation was adequate in this regard.
4. Florida’s Construction of the Term “Especially Heinous, Atrocious or Cruel” (Claim 5)
Bertolotti argues that the Supreme Court’s recent decision in Maynard v. Cartwright invalidates the death sentence he received. 486 U.S. 356, 108 S.Ct. 1853, 100 L.Ed.2d 372 (1988). In Cartwright, the Supreme Court vacated an Oklahoma death sentence because the trial judge did not give the sentencing jury an adequately narrow explanation of the term “especially heinous, atrocious or cruel,” as that term was used in a statutory aggravating circumstance found by the sentencing jury. Bertolotti reasons that because identical language was used to establish one of the three statutory aggravating circumstances that supported his sentence, and because the trial judge did not give the jury a narrowing construction of the term, his sentencing process was unconstitutionally flawed. We reject this claim.
In Lindsey v. Thigpen, 875 F.2d 1509 (11th Cir.1989), we recently interpreted Cartwright and Godfrey v. Georgia, 446 U.S. 420, 100 S.Ct. 1759, 64 L.Ed.2d 398 (1980), to establish three factors for a federal habeas court to consider in ruling on eighth-amendment vagueness challenges such as the one here asserted:
First, the appellate courts of the state must have narrowed the meaning of the words “heinous, atrocious or cruel” by consistently limiting their application to a relatively narrow class of cases, so that their use “inform[s] [the sentencer of] what [it] must find to impose the death penalty.” Cartwright, 108 S.Ct. at 1858. Second, the sentencing court must have made either an explicit finding that the crime was “especially heinous, atrocious or cruel” or an explicit finding that the crime exhibited the narrowing characteristics set forth in the state-court decisions interpreting those words. Third, the sentencer’s conclusion — that the facts of the case under consideration place the crime within the class of cases defined by the state court’s narrowing construction of the term “heinous, atrocious or cruel” — must not have subverted the narrowing function of those words by obscuring the boundaries of the class of cases to which they apply.
875 F.2d at 1514.
A plurality of the United States Supreme Court decided in 1976 that Florida courts had adequately limited the class of capital murders to which this aggravating circumstance can be applied consistently with the requirements of the eighth amendment. Florida’s appellate construction, holding the term to mean “the conscienceless or pitiless crime which is unnecessarily torturous to the victim,” provides sufficient guidance “to those charged with the duty of recommending or imposing sentences in capital cases.” Proffitt, 428 U.S. at 255-56, 96 S.Ct. at 2968 (plurality opinion of Stewart, Powell & Stevens, JJ.). Cf. Lind*1527sey, 875 F.2d at 1514 (identical construction).
Second, the trial judge, who under the Florida death-penalty statute is the sen-tencer, Fla.Stat.Ann. § 921.141(3), explicitly found the facts to warrant the aggravating circumstance. Thus, the sentencing judge specifically concluded that:
The capital felony was especially heinous, atrocious, or cruel. After hearing the Defendant’s own account of this murder and considering the physical evidence it is difficult for the mind to imagine the horror and pain that Carol Ward must have suffered during the defendant’s clumsy and protracted efforts to kill her. There is no question that she was stripped or forced to disrobe, threatened, bludgeoned, strangled and repeatedly stabbed. Her wounds clearly demonstrate that she tried to defend herself. A knife was actually broken from its handle in the first series of stabbings. Because she was “still moving” the defendant left the area and then returned with a second knife to continue the stabbing.
See Palmes v. Wainwright, 725 F.2d 1511, 1523-24 & n. 12 (11th Cir.), reh. in banc den., 729 F.2d 1468 (11th Cir.), cert. denied, 469 U.S. 873, 105 S.Ct. 227, 83 L.Ed.2d 156 (1984). We have no reason to doubt that the sentencing judge, “who is presumed to know and apply the appropriate, narrow construction” of the aggravating circumstance, was guided by the Florida appellate construction of the words “especially heinous, atrocious or cruel.” Lindsey, 875 F.2d at 1514 n. 5. Nor do the circumstances recounted by the sentencing judge give any indication that Bertolotti was sentenced to death as a result of the sentencer’s belief that any intentional murder is especially heinous, atrocious or cruel. Cf. Cartwright, 108 S.Ct. at 1859; Godfrey, 446 U.S. at 428-29, 100 S.Ct. at 1765.
Finally, by finding that these facts exemplified “heinous, atrocious or cruel” behavior, the sentencer did not subvert the eighth-amendment channelling function of that term as narrowed by the Florida supreme court. Even though not required by the eighth amendment, the aggravating circumstance here was applied to a case presenting “torture or serious physical abuse,” Cartwright, 108 S.Ct. at 1859; we therefore can see a “principled way to distinguish this case, in which the death penalty was imposed, from the many cases in which it was not.” Godfrey, 446 U.S. at 433, 100 S.Ct. at 1767.
5. “Automatic” Aggravating Circumstance (Claim 6)
Bertolotti was convicted of felony murder; later, following the penalty phase of his trial, the sentencer found in aggravation of Bertolotti’s crime the circumstance that he murdered while in the course of a robbery. Bertolotti argues that his conviction during the guilt phase thus insured a sentence of death during the penalty phase, and as such the death penalty was unconstitutional.
The Supreme Court recently rejected a nearly identical claim. Lowenfield v. Phelps, 484 U.S. 231, 108 S.Ct. 546, 98 L.Ed.2d 568 (1988). In Lowenfield, the petitioner had been convicted of a death-eligible murder under a statute that required the jury to find that “the offender has a specific intent to kill or to inflict great bodily harm upon more than one person.” 484 U.S. at —, 108 S.Ct. at 554. The only aggravating circumstance found by the jury to justify the death penalty was that “the offender knowingly created a risk of death or great bodily harm to more than one person”; the statute and the aggravating circumstance were “interpreted in a ‘parallel fashion’ ” under state law. Id. Rejecting the petitioner’s assignment of error, the Supreme Court noted that “[t]he use of ‘aggravating circumstances’ is not an end in itself, but a means of genuinely narrowing the class of death-eligible persons and thereby channeling the jury’s discretion. We see no reason why this narrowing function may not be performed by jury findings at either the sentencing phase of the trial or the guilt phase.” Id.
The Lowenfield reasoning applies to the instant case: Florida may narrow the class of death-eligible defendants at either the guilt phase or the penalty phase of capital trials. Moreover, consistent with the judge’s instructions, see supra Part II.C.2, the jury could have found Ber-*1528tolotti guilty of felony murder and yet still not have concluded that the parallel aggravating circumstance justified the imposition of capital punishment; nor need the sentencing judge have agreed with the jury’s determination that felony murder had been proven beyond a reasonable doubt. Cf. supra Part II.B.l (judge did not agree with jury’s finding that burglary and sexual battery had been proven beyond a reasonable doubt). In no sense did the jury’s verdict of felony murder automatically predestine the judge’s imposition of Florida’s highest penalty. See Adams, 709 F.2d at 1447.22
6. “Victim Impact” Evidence (Claim 7)
During the sentencing phase of the trial, the prosecutor engaged the victim’s husband in the following colloquy:
A: If I was home, my wife would open a door, although she would prefer I do so. Throughout our marriage she often was upset if I opened the door to strangers, mentioning the danger there might be. I did not feel that danger, but my wife did.
Q: All right, sir. Now, was she particularly concerned with black strangers?
Defense: Your Honor, I’m going to object to leading the witness and suggesting the answer.
Court: Sustained. Reframe your question.
Q: Did she have any particular concerns about who the strangers were that would come to the door?
A: All strangers upset my wife if they were young and male.
Bertolotti argues that this colloquy introduced impermissible victim-impact evidence into the trial. See South Carolina v. Gathers, — U.S. —, 109 S.Ct. 2207, 104 L.Ed.2d 876 (1989); Booth v. Maryland, 482 U.S. 496,107 S.Ct. 2529, 96 L.Ed.2d 440 (1987). This evidence was not introduced for the purpose of establishing the personal worth of the victim, decrying the emotional impact of the murder upon the Ward family, or describing the family’s perception of the crime. Cf. Gathers, 109 S.Ct. at 2210; Booth, 482 U.S. at 498, 107 S.Ct. at 2531. Rather, the prosecutor introduced the evidence to rebut Bertolotti’s defense to burglary — that he had been invited into the Ward home. This evidence “relate[d] directly to the circumstances of the crime,” and was “relevant to rebut an argument offered by the defendant.” Booth, 482 U.S. at 507 n. 10, 107 S.Ct. at 2535 n. 10; cf. Gathers, 109 S.Ct. at 2211 (text of papers carried by victim not relevant to circumstances of the crime because there was no likelihood that petitioner had read the text or murdered the victim because of the text). Moreover, and as the district court concluded, this colloquy is of a markedly different scope and tone from the evidence condemned by the Booth Court. As the evidence was relevant to prove a fact in issue, cf. Fed.R.Evid. 401 & 402, and not overly prejudicial or inflammatory, cf. Fed. R.Evid. 403, we cannot say that this information was “constitutionally impermissible or totally irrelevant to the sentencing process.” Cf. Booth, 482 U.S. at 502, 107 S.Ct. at 2533 (quoting Zant v. Stephens, 462 U.S. 862, 885, 103 S.Ct. 2733, 2747, 77 L.Ed.2d 235 (1983)).
III. CONCLUSION
We are satisfied that the petitioner’s conviction and sentence of death were obtained by the State of Florida consistently with the requirements of the United States Constitution. Accordingly, we AFFIRM the district court’s decision denying Anthony Bertolotti the writ of habeas corpus.
. The warrant period commenced at noon on February 15, 1989, and was to expire at noon on *1508February 22, 1989. The warden scheduled Ber-tolotti’s execution for seven o’clock a.m. on February 16, 1989. Bertolotti, through his counsel the Office of the Capital Collateral Representative, immediately lodged in federal district court and in this court substantial portions of the voluminous state-court record. On February 9, 1989, the district court received an additional volume containing all documents relating to Bertolotti’s appeals to the Supreme Court of Florida.
. Bertolotti immediately filed in this court motions for a certificate of probable cause to appeal and for an additional stay, and also filed an appeal of the district court’s decision denying the writ of habeas corpus. We granted the motion for stay on February 15, 1989, in order to allow oral argument on the district court's denial of both the certificate of probable cause and the writ of habeas corpus. See 11th Cir.R. 22-3(a)(7). Following oral argument on February 18, 1989, we granted Bertolotti's certificate of probable cause, but by a divided panel affirmed the denial of relief. Bertolotti immediately filed motions for a stay of execution, for rehearing by the panel, and for rehearing in banc. Pending resolution of these motions, Ber-tolotti’s execution was stayed until seven o’clock a.m., February 21, 1989. On February 20, 1989, we vacated our prior panel opinion, granted a new certificate of probable cause, and agreed to rehear argument on the merits of Bertolotti’s appeal.
. The facts upon which Bertolotti’s conviction and sentence are based are recounted in the Florida Supreme Court's opinion on direct appeal, Bertolotti v. State, 476 So.2d 130 (1985), and will not be repeated in their entirety here.
. In the vacated order, the majority and the dissent agreed that this particular claim was the only claim presented by Bertolotti which had any merit; the majority did not address the competency of Bertolotti's counsel, resolving the claim on the ground that Bertolotti had shown no prejudice. See Strickland, 466 U.S. at 697, 104 S.Ct. at 2069 (court should dispose of claim on prejudice prong if that course is “easier”).
. The state rule does not necessarily define a “prevailing professional norm" within the Supreme Court’s use of the term. Strickland, 466 U.S. at 688, 104 S.Ct. at 2065 (referring to prevailing norms in terms of American Bar Association standards). Otherwise, the content of a fundamentally fair trial would vary from state to state.
. The dissent submits that "[cjharacterizing counsels' accidental failure to secure a mental exam until the morning of the sentencing hearing as a 'decision' that must be evaluated for ‘reasonableness’ oversteps the settled law of this Circuit regarding this issue.” Dissent at 1531. We explain infra that counsel’s failure to obtain a mental examination prior to trial is understandable because the total picture confronting counsel did not suggest the necessity of such an examination to Bertolotti's defense on the merits; the circumstances were not such as to call for a documented, plotted-out strategic choice between mental examination or no mental examination, which is what the dissent apparently would like to review. Therefore, without joining an abstract debate over the meaning of the term "decision," we think counsel’s failure to schedule a mental examination prior to the guilt phase of the trial is properly judged under a standard of reasonableness.
. Bertolotti attaches some significance to the fact that counsel requested a psychiatric examination and the court granted that request, but counsel failed to schedule the examination until the morning of the sentencing hearing. Also, the dissent emphasizes that "the fact that a psychiatric evaluation was both requested and granted and the fact that a psychiatrist was obtained to conduct an evaluation right before the sentencing hearing belies a conclusion that counsel had no reason to suspect mental illness.” Dissent at 1530. As the following colloquy between attorney Wolfe and the state attorney at the evidentiary hearing indicates, and as the district judge found, Wolfe simply asked for the examination as a matter of course:
Q; Mr. Wolfe, why did you file a motion to have Mr. Bertolotti examined?
A: Prior to accepting this assignment, I had gone up to the public defender’s office in Jacksonville in the Fourth Circuit, Duval County, and they had prepared from their word processor a whole list of motions. And I spent the day with the chief assistant up there, Bill White, discussing representation of this type of case. And that was the type of motion that they had indicated to me should be filed in every case to begin an investigation.
It didn’t dawn on — I didn’t realize how much importance should be placed on that until later and how that should be independently followed up in addition to the basic factual case preparation.
Q: Mr. Wolfe, at the time that you filed that motion, did you have facts in your possession, based upon your interview with Mr. Bertolotti, based upon what you knew about the facts of this case and based upon the background information that you had, that would substantiate and support that motion?
A: Well, the threshold for that motion is not that great, and — or at least my reading of the rules is that the threshold requirements for that particular motion are not that great, so I would have to say yes with a liberal interpretation of the rules.
Q: Did you think Mr. Bertolotti was incompetent?
A: Incompetent to stand trial?
Q: Yes, sir.
A: I didn't think so.
Q: Did you think Mr. Bertolotti, based upon what you knew of the facts and how this crime was committed, was insane at the time of the commission of this crime?
A: From what I knew at the time, I don’t think so.
. The dissent states that “[i]n an attempt to dismiss the evidence as insufficient to alert the attorneys to the possibility of Bertolotti’s insanity, the majority dissects the evidence and discusses the insufficiency of each ‘alleged signal’ of mental instability. This seriatim analysis wholly fails to address the bigger picture. The cumulative effect of all the evidence undeniably points to the necessity of ordering a mental health evaluation." Dissent at 1531. We agree with the dissent that such a "seriatim analysis” would be incorrect. As the majority opinion demonstrates, however, we have considered the totality of the evidence available to counsel at the time counsel planned trial strategy.
. Bertolotti argues that without securing a psychiatric examination, counsel could not reasonably have opted to pursue a defense strategy based on lack of premeditation. The Strickland Court rejected a similar argument: counsel there made a strategic choice to rely on his client’s extreme emotional distress, but counsel’s decision not to seek more "psychological evidence than was already in hand” was reasonable. Id., 466 U.S. at 699, 104 S.Ct. at 2070.
. In the course of his testimony, Dr. Merikan-gas made passing reference to other factors in support of his diagnosis. He placed some reliance on a belief that Bertolotti had been under the influence of a quaalude at the time of the murder. The only evidence supporting this proposition is the self-serving statement Berto-lotti made in his first confession; the state offered evidence at trial rebutting the notion that Bertolotti had consumed a quaalude, and at the evidentiary hearing, one of the state’s expert witnesses testified that Bertolotti told him he had lied about taking the quaalude. The Florida Supreme Court concluded as a matter of state law that Bertolotti had not produced enough evidence of intoxication to warrant an intoxication instruction. Bertolotti v. State, 534 So.2d at 387. See infra Part II.A.l.b.
Dr. Merikangas also referred to Bertolotti's second confession, in which he implicated his girlfriend, as evidencing the circumstances of extreme duress which precipitated Bertolotti’s murder of Carol Ward. Bertolotti told police that his girlfriend ordered him to kill the victim because the victim had grabbed the girlfriend’s legs. We doubt a jury would conclude, after hearing audio tapes of both confessions, that Bertolotti’s first confession was a complete fabrication and that his second confession more closely represented the true circumstances of the crime.
. The dissent is "disturbed by the fact that, in reaching its conclusion, the majority has imper-missibly invaded the province of the jury.” Dissent at 1534. However, we point out that Strickland requires habeas petitioners not only to show defective performance of counsel, but also to demonstrate prejudice resulting therefrom. 466 U.S. at 687, 104 S.Ct. at 2064. To gauge prejudice, the federal court must determine whether there is a "reasonable probability” that the newly proffered evidence would have changed the jury’s decision. 466 U.S. at 694, 104 S.Ct. at 2068. The dissent does not suggest how the court can complete this task without "invading the province” of the jury. At any rate, the jury has already spoken in this case. Our only license is to determine, within the bounds dictated by Supreme Court and Eleventh Circuit *1519precedent, whether the performance of Bertolot-ti’s counsel deprived him of a fundamentally fair trial.
.The jury voted nine to three to recommend the death penalty; had three jurors voted differently, the recommendation would have been for life. We reject the argument that analysis of the "reasonable probability” of a different verdict should vary according to the number of jurors voting to impose the death penalty: if there is a reasonable probability that one juror would change his or her vote, there is a reasonable probability that a jury would change its recommendation. Strickland, 466 U.S. at 695, 104 S.Ct. at 2068 ("The assessment of prejudice should proceed on the assumption that the deci-sionmaker is reasonably, conscientiously, and impartially applying the standards that govern the decision. It should not depend on the idio-syncracies of the particular decisionmaker, such as unusual propensities toward harshness or leniency.’’).
. Moreover, after listening to four mental-health experts including Dr. Merikangas, the state trial judge found Dr. Merikangas’s testimony "preposterous.”
. Bertolotti contends that none of the state’s experts rebutted Dr. Merikangas’s opinion in regard to the availability of death-mitigating psychiatric evidence. It is clear that the testimony of any of the state’s witnesses could be used at the penalty phase to contradict Bertolot-ti’s mitigation evidence.
. The trial judge instructed the jury as follows: The fact that your recommendation is advisory does not relieve you of your solemn responsibility, for the court is required to and will give great weight and serious consideration to your verdict in imposing sentence.
. Veniremen were brought into the courtroom one at a time and examined on the subjects of pretrial publicity and personal feelings about the death penalty. Veniremen were admonished not to discuss the individual proceeding with the remainder of the venire.
. In Coleman, rural Seminole County, Georgia, site of the trial, was literally saturated with virulent press reports of the crime for which the habeas petitioner was indicted, tried, and sentenced to death. As the Coleman court's lengthy narrative demonstrates, the case had become notorious throughout Georgia. 778 F.2d at 1491-1537. A local newspaper that reached eighty-five percent of the households in Seminole County, the Donalsonville News, repeatedly published front-page articles, including one *1522front-page editorial, regarding the murder and the defendants. Editorials and articles continued to be published in the News regularly from May 1973 until the trial in January 1974; in September, the News published a letter from the trial judge to the defense attorneys in which the judge warned defense counsel not to "trifle" with the court. Id. at 1496. Emphasizing that the presumed-prejudice standard is only to be invoked under the most extreme of circumstances, we held that the defendant had carried his burden.
. See Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir.1981) (in banc). The Eleventh Circuit adopted as binding precedent all decisions rendered by the former Fifth Circuit prior to October 1, 1981.
. In district court, Bertolotti argued that he was prejudiced by other of the prosecutor’s comments during the penalty phase. The district court rejected the argument, and Bertolotti does not explicitly contest this finding on appeal. Regardless, we agree with the district court’s conclusion that the comments, considered cumulatively or individually, did not deny Bertolotti a fair trial. See abo Bertolotti v. State, 476 So.2d at 133.
Bertolotti characterizes the following prosecu-torial statement as impermissible victim-impact evidence (see infra Part II.C.6):
And Carol Ward is just kind of an abstract person. Everybody’s forgotten about her.
We doubt this statement rises to the level condemned by the Supreme Court in Booth v. Maryland, 482 U.S. 496, 107 S.Ct. 2529, 96 L.Ed.2d 440 (1987). Nevertheless, considered as another element of Bertolotti's prosecutorial-misconduct claim, we do not consider this statement unconstitutionally prejudicial. See Davis v. Kemp, 829 F.2d 1522, 1536 (11th Cir.), reh. in banc den., 835 F.2d 291 (11th Cir.1987), cert. denied, — U.S. —, 108 S.Ct. 1099, 99 L.Ed.2d 262 (1988).
. We need not address the state’s argument that the district judge erred by not finding this claim procedurally barred.
. The Tenth Circuit has held that the trial judge may not specifically instruct the jurors not to consider "sympathy, sentiment, passion, prejudice or other arbitrary factor” during capital sentencing. Parks v. Brown, 860 F.2d 1545, 1552 (10th Cir.1988) (in banc), cert, granted sub nom. Saffle v. Parks, — U.S. —, 109 S.Ct. 1930, 104 L.Ed.2d 402 (1989). Bertolotti’s jury received no such instruction.
. To the extent that Bertolotti challenges the use of felony murder as an aggravating circumstance, he attacks a decision firmly within the discretion of the Florida legislature. Gregg v. Georgia, 428 U.S. 153, 176, 96 S.Ct. 2909, 2926, 49 L.Ed.2d 859 (1976) (plurality opinion of Stewart, Powell & Stevens, JJ.) (determinations of appropriate sentencing considerations are "peculiarly questions of legislative policy"). The Florida statute was adjudged constitutional in Proffitt v. Florida, 428 U.S. 242, 96 S.Ct. 2960, 49 L.Ed.2d 913 (1976) (plurality opinion of Stewart, Powell & Stevens, JJ.).
