concurring:
I am in full accord with Parts II and III of the court’s opinion, and with the court’s conclusion in Part I that the District Judge erroneously excluded Horan’s testimony to an incident that the jury could have interpreted as an act of racial discrimination by appellees against someone other than appellant. I also agree that, in the circumstances of the case, the ruling was not sufficiently prejudicial to require reversal, and that appellant cannot prevail on any other contention he now presses. I wish to emphasize, however, that our holding today is that rejection of this testimony could not be sustained as an appropriate exercise of judicial discretion even absent the compounding effect of two other trial occurrences — the admission of evidence of nondiscrimination proffered by appellees, and the District Judge’s pretrial statement that appellant would be permitted to put on evidence indicating discrimination by appellees against others. In other words, admission of the challenged testimony was required even if it had not b.een aided by these additional factors.
*789Resolution of the evidentiary issue is somewhat handicapped by the fact that, as my colleagues recognize, “[t]he trial court did not specify its reasons for exclusion.”1 Appellees contend2 that Horan’s testimony was kept out as a matter of trial-court discretion in the balancing function summoned by Federal Evidence Rule 403:
Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.3
While it is possible to deduce from the record that the District Judge utilized Rule 403 in barring the testimony,4 the record more readily supports the inference that the theory underlying exclusion was irrelevance.5 But whatever the rationale assumed by the judge as the basis for his action, the ruling cannot pass muster.

In pertinent part, the Fair Housing Act6 declares unequivocably that
it shall be unlawful—
(a) To refuse to . rent after the making of a bona fide offer . or otherwise make unavailable or deny, a dwelling to any person because of race [or] color
(b) To discriminate against any person in the terms, conditions, or privileges of . rental of a dwelling . . . because of race [or] color . . .7
No one suggests that the case before us is exempt from these provisions,8 nor can it be *790gainsaid that conduct described by the Act transgresses its terms when motivated by considerations of race or color.9 So, in the case at bar, proof that appellees acted with racial animus in taking the complained-of actions against appellant would clearly have been sufficient, though possibly not essential,10 to establish a violation of the Act. The question, then, is whether Horan’s testimony was competent and relevant on that score.
There is no doubt whatever that the answer must be in the affirmative. Rule 404(b) provides that “[e]vidence of other . acts . . . may ... be admissible [to prove] motive [or] intent.”11 This canon incorporates a longstanding and broadly operative principle,12 and there is *791no reason why it should not apply here. As ' the court’s opinion states, “it is clear that the proffered evidence of past acts of racial discrimination was relevant to prove the landlord’s motive in his action towards appellant.” 13
This conclusion finds ample support in the caselaw, perhaps nowhere more strongly than in the Supreme Court’s decision in McDonnell Douglas Corp. v. Green,14 wherein the Court delineated “the order and allocation of proof in a private, non-class action challenging employment discrimination.”15 After the plaintiff has carried the initial burden of establishing a prima facie case of racial discrimination,16 said the Court, the burden shifts to the defendant “to articulate some legitimate, non-discriminatory reason” for his conduct.17 If that reason sufficiently meets the plaintiff’s prima facie case, the plaintiff must then “be afforded a fair opportunity to show that [the defendant’s] stated reason for [his actions] was in fact pretext.”18 Very importantly for the case before us, the Court specifically noted that “[o]ther evidence that may be relevant to any showing of pretext includes facts as to . [the defendant’s] general poli*792cy and practice with respect to minoritpes].”19
Relying on McDonnell Douglas, we recently held in Kinsey v. First Regional Securities, Inc.,'20 a discrimination suit brought by but one individual, that exclusion of “evidence of hiring practices and statistical data” 21 on grounds of irrelevance constituted reversible error even though the evidence related to different jobs and different time periods from those cited in the plaintiff’s complaint.22 Moreover, the McDonnell Douglas-Kinsey approach to the admissibility of other-acts evidence23 has been endorsed by numerous other courts in nonclass employment-bias24 and fair-housing25 actions. So commonly has other-acts evidence been utilized in individual nonclass discrimination suits that courts frequently admit it without any felt need to elucidate a rationale for their actions.26
*793In several nonclass housing discrimination cases, evidence nearly identical to that offered here has been admitted as clearly relevant. In Smith v. Anchor Bldg. Corp.,27 the plaintiff, suspecting that she had been denied an apartment because she was black, enlisted the aid of a local civil rights organization. The latter dispatched to the apartment complex in question a white “checker,”28 whose “function ... in this context was to compare rental procedures as applied to black and white persons.”29 The checker’s observations were let in, the Eighth Circuit noting on appeal that such activity “has been uniformly admitted into evidence to show the existence of discrimination.” 30 Evidence of a nearly contemporaneous rejection of another black applicant was also received, the Court of Appeals remarking that it was “highly probative.” 31
Similarly, in Wharton v. Knefel,32 evidence showing that a defendant landlord had offered to lease an apartment to a prospective black tenant a year and a half before she turned the also-blaek plaintiff down was considered in arriving at the conclusion that the plaintiff was not denied housing on the basis of race.33 And in Bishop v. Pecsok,34 evidence disclosing that a landlord had informed another black applicant that he did not rent to blacks was relied upon to support the court’s holding that rejection of the black plaintiff’s application was founded on race.35
Perhaps these examples might be multiplied, but more is hardly necessary. The probative value of other-acts evidence in nonclass discrimination suits is satisfactorily established. Exclusion of Horan’s testimony to appellees’ discriminatory acts against others than appellant cannot be sustained on the notion that it was irrelevant.
II
For these reasons, evidence of this nature was entitled to a role in appellant’s effort to demonstrate appellees’ motive in treating him as they did. Appellees contend, however, that the decision on Horan’s testimony could nevertheless have been proper as an exercise of judicial authority under Rule 403.36 Although “the trial judge’s weighing of evidence against the criteria of Rule 403 is a matter within his discretion,”37 there are limits on the discretion conferred by Rule 403,38 and irredeemably they were exceeded here.
To begin with, any grant of discretion contemplates that it will be exercised — one way or the other — when the situation giving it birth makes its appearance. Beyond that, discretion is abused if clearly probative evidence is excluded when there is virtually no danger of unfair prejudice, issue-confusion or other Rule 403 factors militat*794ing against admission.39 Scrutinizing this case within these limits, it must first be noted that there is nothing on the record before us to indicate that the District Judge ever drew upon his Rule 403 discretion — by weighing appropriate factors40 — in concluding that Horan’s testimony was inadmissible,41 and that the uncertainty in this regard could be removed only by a remand with instructions to explicate the reasons for concluding that exclusion was in order.42 There is no need for that, however, for, even assuming that the judge actually endeavored to strike the balance required by Rule 403, exclusion was erroneous under the abuse-of-discretion standard.
*795Appellees contend,43 that the probative value of Horan’s testimony was outweighed by its prejudicial proclivity. The difficulty in that position is that the prejudice to which Rule 403 speaks is something utterly different from the capability of the evidence to debilitate the opponent’s cause in an entirely legitimate manner. The prejudice that Rule 403 specifies as a factor working against the admission of relevant evidence is “unfair prejudice,”44 and “ ‘[ujnfair prejudice’ . . . means an undue tendency to suggest decision on an improper basis, commonly, though not necessarily, an emotional one.”45 Though arguably, as appellees claim,46 Horan’s testimony might have engendered some chance that the jury might penalize appellees for discriminating against someone other than appellant, its exclusion could not possibly have been justified in the face of the much more powerful considerations on the other side. Horan’s testimony had no special attribute of unfair prejudice that would distinguish it from the general body of other-acts evidence thought to be so relatively free of a potential for unfair application that courts routinely admit it in nonclass discrimination suits without any discussion of prejudice.47 Remoteness of the danger to which appellees advert is further attested by the fact that they cite no case — -nor have we found any — in which evidence of this kind was excluded on the basis of unfair prejudice. Doubtless that is because the evidence not only is relevant, as everyone concedes, but is the only indication— other than the defendant’s say-so — of what his state of mind might have been when he acted.48
Rule 403 does not precondition the admissibility of other-acts evidence upon a guaranty that its use by the jury will be impeccable. It recognizes fully the value of limiting instructions, and contemplates that “[i]n reaching a decision whether to exclude on grounds of unfair prejudice, consideration [will] be given to the probable effectiveness or lack of effectiveness of a limiting instruction.”49 No reason whatever is suggested as to why in the instant case the already miniscule risk that the jury might go astray could not have been acceptably mitigated, if indeed not eradicated, by an instruction confining the jury’s utilization of Horan’s testimony specifically to the issues of intent and motive on which it was sought to be admitted.
Finally, appellees also suggest that Horan’s testimony could properly have been excluded because it would have interjected collateral issues likely to confuse or mislead the jury and waste time.50 Here again, no case in which other-acts evidence was rejected on this premise has been uncovered. Quite to the contrary, in Corley v. Jackson Police Department51 the Fifth Circuit held flatly that such evidence properly directed does not pose the hazard of collateral disputes:
It is apparent . . . that the district court . . . viewed all evidence relevant to pretext — the treatment of other officers similarly accused . and the history of racial discrimination within the Jackson police — as ‘collateral questions’ . . . . But under McDonnell Douglas, such evidence is not merely collateral; it is an indispensable element of the plaintiff’s burden of proof and must be confronted by the district court in finding for either party. Such evidence does not becloud any issue in this case; rather, it directly addresses and *796sharply defines a key issue, as developed in McDonnell Douglas and its progeny.52

As an eminent jurist once observed, under certain conditions a decision normally committed to a trial court’s discretion may become the subject of a judicial rule:
Several of the most important reasons for deferring to the trial judge’s exercise of discretion — his observation of the witnesses, his superior opportunity to get ‘the feel of the case,’ see Cone v. West Virginia Pulp & Paper Co., 330 U.S. 212, 216, 67 S.Ct. 752, 91 L.Ed. 849 (1947), and the impracticability of framing a rule of decision where many disparate factors must be weighed, see Atchison, T. & S.F. Ry. v. Barrett, 246 F.2d 846 (9th Cir. 1957) — are inapposite when a question arising in advance of trial can be stated in a form susceptible of a yes-or-no answer applicable to all cases. . . . 53
And as a discerning commentator has similarly noted, a primary reason for a policy of deference is that the issues involved are of such character that they do not lend themselves to sound resolution by application of a general rule.54 The frequency with which other acts evidence has been admitted in discrimination cases without question or apparent ill consequences suggests that a judicial rule favoring its normal admission has arisen already de facto. However that may be, at the very least a failure to follow clear precedent in an unexceptional case falls fatally short of a sound exercise of judicial discretion.
An important public policy is subserved by admission of evidence of other acts of discrimination or nondiscrimination on the part of a defendant whose motivation vis-avis the plaintiff has been drawn into question. As the populace has become more and more aware of the illegality of disparate treatment attributable to racial or some other invidious classification, discriminatory practices have become increasingly subtle. Absent something amounting well nigh to an open admission of discriminatory purpose, victims may find it virtually impossible to prove that fact unless permitted to introduce evidence that the defendant has engaged in one or more acts of discrimination against others. At the same time, a defendant falsely accused of discriminating against the plaintiff should not be made to forego an opportunity to demonstrate lack of bias — more palatably than by his unsupported disavowal alone — by evidence reflecting nondiscriminatory activity on other occasions. These are wholly legitimate concerns when the operation of Rule 403 is subject to judicial inquiry. As the Advisory Committee has expressly stated, “[t]he availability of other means of proof may also be an appropriate factor” for consideration in instances implicating Rule 403.55 Here it should be given the prominence it is justly due.
In sum, whether Horan’s testimony was excluded on a theory that it was irrelevant or that its probative value was outweighed by the likelihood of a prejudicial impact or the generation of collateral issues, the District Judge’s ruling cannot stand.56 Other *797trial occurrences enhanced the error in this ruling, but it was amiss even without those additional considerations. That is not to say that other-acts evidence can never be barred on grounds of prejudice or collateralness. It is to say that before it is rejected the record should show that it possesses characteristics presenting much more of a special and insuperable difficulty than appears here.

Your Honor, we would say under the Federal Rules it is such inflammatory evidence that, even if it is relevant and material, it should be eliminated, because, in weighing the probative weight of the evidence against the danger of the jury getting confused, we think it ought to be kept out.
This case is getting very far afield. We have to try to confine it to him.
Tr. 278-279.
. When trial counsel for appellant offered Horan as a witness, the following colloquy with the court transpired:
THE COURT: Now what did I rule yesterday, just to test your recollection with respect to this business about pattern and practice of discrimination? What did I rule?
[COUNSEL]: Your Honor, this is not a pattern.
THE COURT: All right. What did I rule with respect to this?
[COUNSEL]: That there would be no evidence admitted except evidence relating to similar incidents as those suffered by [appellant] at the same time in the Crestwood. I understood that that evidence was to be admissible.
We do not consider this a pattern and practice, Your Honor. This is relevant evidence, admissible under the Federal Rules of Evidence, without any regard to a pattem-andpractice theory.
Tr. 277. After appellant’s trial counsel proffered the evidence, the judge remarked:
Now, what has that to do with showing racial discrimination against [appellant], other than possibly this business about a pattern and practice, which we all agreed was not an issue in this case?
Tr. 279.
In sum, the only indication in the record that the District Judge relied on Rule 403 in excluding Horan’s testimony emerges in the form of argument by defense counsel, which did not even cite Rule 403. See note 4 supra. In contrast, the judge’s expressions pointed to concern only of the relevance of pattem-andpractice evidence of the issue of discrimination against appellant as an individual.

. “Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith. It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.” Fed.R.Evid. 404(b).
The Advisory Committee’s Note to Rule 404(b) explains that it
deals with a specialized but important application of the general rule excluding circumstantial use of character evidence. Consistently with that rule, evidence of other crimes, wrongs, or acts is not admissible to prove character as a basis for suggesting the inference that conduct on a particular occasion was in conformity with it. However, the evidence may be offered for another purpose, such as proof of motive, opportunity, and so on, which does not fall within the prohibition. In this situation the rule does not require that the evidence be excluded. No mechanical solution is offered. The determination must be made whether the danger of undue prejudice outweighs the probative value of the evidence in view of the availability of other means of proof and other factors appropriate for making decisions of this kind under Rule 403. Slough and Knightly, Other Vices, Other Crimes, 41 Iowa L.Rev. 325 (1956).
When the House Committee on the Judiciary examined Rule 404(b) in the form proposed to it, it made an important change in language reflecting an equally important change in emphasis:
The second sentence of Rule 404(b) as submitted to the Congress began with the words “[tjhis subdivision does not exclude the evidence when offered”. The Committee amended this language to read “[ijt may, however, be admissible”, the words used in the 1971 Advisory Committee draft, on the ground that this formulation properly placed greater emphasis on admissibility than did the final Court version.
H.R.Rep.No.93-650, 93d Cong., 1st Sess. 7 (1973) .
The report of the Senate Committee on the Judiciary reflects the same concern:
[T]he use of the discretionary word “may” with respect to the admissibility of evidence of crimes, wrongs, or acts is not intended to confer any arbitrary discretion on the trial judge. Rather, it is anticipated that with respect to permissible uses for such evidence, the trial judge may exclude it only on the basis of those considerations set forth in Rule 403, i. e. prejudice, confusion or waste of time.

. Id. at 800, 93 S.Ct. at 1823, 36 L.Ed.2d at 676. Although McDonnell Douglas was decided under Title VII of the Civil Rights Act of 1964, 42 U.S.C. §§ 2000e et seq. (1976), the reasoning there seems equally applicable to private nonclass actions alleging discrimination in violation of the Fair Housing Act. The language of the two Acts is very similar; under both, conduct otherwise lawful becomes unlawful if motivated by a racial consideration. Compare 42 U.S.C. § 2000e-2(a) (1976) (discharging an employee, refusing to hire an applicant for employment, or offering individuals different levels of compensation or different terms and conditions of employment unlawful if based on race) with 42 U.S.C. § 3604 (1976) (refusing to sell or rent a dwelling to an individual with a bona fide offer, refusing to negotiate for the sale or rental of a dwelling, or offering individuals different terms, privileges, or conditions of sale or rental of a dwelling unlawful if based on race).
The problem faced in McDonnell Douglas was whether an employment decision had been based on a legitimate ground or whether it was the product of discrimination against the plaintiff because of his race. Because the Fair Housing Act like Title VII, requires a plaintiff to show that he was denied his right to fair housing because of his status as a member of a protected class rather than for some valid reason, the problem of distinguishing racially-motivated from legitimately-motivated conduct arises just as it does under Title VII. Consequently, it would appear that the standards enumerated in McDonnell Douglas are applicable in nonclass suits alleging Fair Housing Act violations. See Weathers v. Peters Realty Corp., 499 F.2d 1197, 1201-1202 (6th Cir. 1974) (drawing analogies between use of statistics in Fair Housing Act cases and use of statistics in school segregation and employment discrimination cases); Smith v.

Pecsok, supra note 9, 431 F.Supp. at 36 (evidence that landlord had told another black applicant that *793he did not rent to blacks, and evidence that “no blacks lived in [defendant’s] apartment” on the date plaintiff was denied an apartment “and few, if any, ever lived there” relied on to support conclusion that rejection of plaintiffs application was based on race).

. Judge Weinstein suggests that “[djespite the large powers granted by the rule, Rule 403 should be applied infrequently and cautiously by trial judges.” J. Weinstein and M. Berger, Evidence fl 403[02] at 403-14 (1977). Support for this position is found in “the history of opposition to the Model Code and Uniform Rules, as well as the concern of draftsmen of the Federal Rules of Evidence.” Id. at 403-13 to 403-14.
. See, e. g., United States v. Dwyer, 539 F.2d 924, 927-928 (2d Cir. 1976) (exclusion of expert testimony relevant to defendant’s insanity defense constituted abuse of discretion granted by Rule 403); Posttape Assocs. v. Eastman Kodak Co., 537 F.2d 751, 757-758 (3d Cir. 1976) (exclusion of evidence of insurance coverage constituted abuse of discretion because evidence was relevant and prejudice unlikely because both parties were commercial entities).
Application of the abuse-of-discretion standard inexorably requires that this appellate court engage to some degree in the weighing process mandated by Rule 403. Judge Weinstein suggests that “[t]he usual approach on the question of admissibility on appeal is to view both probative force and prejudice most favorably towards the proponent, that is to say, to give the evidence its maximum reasonable probative force and its minimum reasonable prejudicial value.” J. Weinstein and M. Berger, Evidence fl 403[03] at 403-18 (1977). This comports with the “thrust of the Federal Rules” which “favors admissibility.” Id. And, emphasizing the strong policy in favor of full development of the evidence in federal litigation, the Supreme Court quite recently commented:
The need to develop all relevant facts in the adversary system is both fundamental and comprehensive. . . . The very integrity of the judicial system and public confidence in the system depend on full disclosure of all the facts, within the framework of the rules of evidence.
United States v. Nixon, 418 U.S. 683, 709, 94 S.Ct. 3090, 3108, 41 L.Ed.2d 1039, 1064 (1974); see United States v. King, 73 F.R.D. 103, 105-106 (E.D.N.Y.1976).
. Speaking in the context of trial-court authority to admit or exclude hearsay reputation testimony, the Supreme Court has admonished that “[w]ide discretion is accompanied by heavy responsibility on trial courts to protect the practice from any misuse.” Michelson v. United States, 335 U.S. 469, 480-481, 69 S.Ct. 213, 221, 93 L.Ed. 168, 176 (1948). The Court went on to praise the trial court’s careful consideration of appropriate factors. Id. at 481, 69 S.Ct. at 221, 93 L.Ed. at 176. The best evidence that a trial court has properly exercised its discretion is explication on the record of his reasons for acting. See note 41 infra.
. See note 1 supra. The weighing process should be conducted explicitly on the record. As this court recently stated:
[W]hat is required of the judge is a balancing of the probative value of and need for the evidence against the prejudicial impact. Sometimes this analysis is cursory and appears only by implication . . .. To avoid
the possibility [of] confusion ... it would be preferable to confront the problem explicitly acknowledging and weighing both the prejudice and the probative worth of impeachment in the spirit of balancing stress in [Rule 403],
United States v. Robinson, 174 U.S.App.D.C. 224, 229, 530 F.2d 1076, 1081 (1976). See United States v. Dwyer, supra note 39, 539 F.2d at 928 (“[ajlthough Rule 403 has placed great discretion in the trial judge, discretion does not mean immunity from accountability;” trial judge should have put reasons for exclusion on trial record); John McShain, Inc. v. Cessna Aircraft Co., 563 F.2d 632, 635 (3d Cir. 1977) (“the balance required [by Rule 403] is not a pro forma one. A sensitive analysis of the need for the evidence as proof on a contested factual issue, of the prejudice which may eventuate from admission, and of the public policies involved is in order before passing on such an objection. The substantiality of the consideration given to competing interests can be best guaranteed by an explicit articulation of the trial court’s reasoning”); J. Weinstein and M. Berger, Evidence j] 403[02] at 403-14 to 403-15 (1977) (“when [Rule 403] is used, a clear statement of the reasons should be made for the record”); M. Rosenberg, Judicial Discretion of the Trial Court, Viewed from Above, 22 Syracuse L.Rev. 635, 666 — 667 (1971) (“[t]o play fair, a trial judge relying upon discretionary power should place on the record the circumstances and factors that were crucial to his determination ... so that counsel and the reviewing court will know and be in a position to evaluate the soundness of his decision”).
. See Contemporary Mission, Inc. v. Famous Music Corp., 557 F.2d 918, 928 (2d Cir. 1977) (“because [the trial court] did not reach these issues, and because we believe it would be inappropriate for this Court to engage in Rule 403 balancing in the first instance, the case must be remanded to the district court for the purpose of making a Rule 403 determination”).

Both sides to the instant controversy have generously offered to supply us with the basis for [the trial court’s] conclusion.
* * * * * * Despite careful consideration of the arguments of counsel, we are unable to ascertain what actually did or permissibly could have prompted the trial judge to act as he did. We therefore conclude that the exclusion of [the] testimony . . constituted an abuse of discretion.
