Twice a jury has concluded that a release signed by Eugene Pierce in favor of his former employer, Santa Fe Railroad Co. (“Santa Fe”), did not constitute a knowing and voluntary waiver of his rights under the Age Discrimination in Employment Act (“ADEA”), 29 U.S.C. §§ 621-634. On review of the first such conclusion, this court acknowledged that ADEA rights could be relinquished through a knowing and voluntary waiver and held that whether a waiver was knowing and voluntary should be determined by looking to the totality of the circumstances surrounding the waiver.
I.
The underlying facts are presented at length in our first opinion, but we will briefly recount them here. In July 1989, Santa Fe fired Pierce from his job as a Senior Analyst, a nonunion position to which Pierce had climbed the previous year after working for more than a decade in various union posts. At the time, the railroad offered Pierce a $19,000 severance package, conditioned on his signing a general release of all claims against Santa Fe. Pierce rejected the offer and chose instead to exercise his union seniority rights, which enabled him to secure a position as a file room clerk. His woes continued, however, for after only two days, a more senior employee took Pierce’s job and relegated him to the role of assistant file room clerk. Unwilling to accept Santa Fe’s explanation that a reduction in force had necessitated the elimination of his Senior Analyst position, Pierce filed claims of age and race discrimination with the EEOC in October 1989.
In November, hearing rumors that his department was to relocate from Illinois, Pierce approached George Pacocha, a Santa Fe official, about receiving a severance package. Pierce had learned from his fellow workers that Santa Fe had offered other union employees a “360” package and he was curious to know whether he was eligible. 1 Pacocha initially responded that he would have to check with his superiors; when the two men subsequently met on either the Tuesday or the Wednesday before Thanksgiving, Paco-eha told Pierce that he could receive the severance package provided that he signed by day’s end a general release of all claims against Santa Fe. At this point, Pierce informed Pacocha of the EEOC complaint and asked whether the release would preclude the discrimination claims. Pacocha responded that he did not believe the release would bar Pierce’s claims, and gave Pierce until the following business day (either Wednesday or Monday) to decide whether to sign it and accept the severance package.
When the two men next met, Pacocha again advised Pierce of the legal consequences of his signing the release. Exactly what Pacocha told Pierce at this second meeting is a matter of considerable dispute, but the result of the meeting was that Pierce accepted the severance package and signed the release, which included the following terms:
For and in consideration of the sum of $36,871.20, subject to the usual deductions, the receipt of which is hereby acknowledged, I hereby knowingly and voluntarily resign from the service of The Atchison, Topeka and Santa Fe Railway Company.
I understand and agree, in consideration of the above specified amount, that this voluntary resignation constitutes a complete relinquishment and surrender unto said Rahway Company, of any and all my rights including seniority, Health and Welfare, and other rights and benefits which may heretofore have accrued to me as an employe[e] of said Railway Company.
I further understand that this voluntary resignation constitutes full settlement and release of any and all claims of any nature, known or unknown, which I have or might have against said Railway Company, including, but not limited to, claims which derive from or are based on any aspect of my preceding employment relationship with said Railway Company or my resignation of such employment. 2
Despite having signed this release, Pierce filed suit against Santa Fe in June 1991 upon receiving notice from the EEOC of his right to sue.
At the first trial, the jury found that the release did not bar Pierce’s claims, found that Santa Fe had discriminated against Pierce on the basis of age, awarded him back pay, and doubled this award based upon a finding of willful discrimination.
See
On appeal, we held that the evidence was sufficient to support the jury’s finding of age discrimination, although we reversed the finding of willfulness. Id. at 572-74. We also held, however, that, as a matter of contract law, the release unambiguously covered Pierce’s claims. Id. at 568. Rejecting Pierce’s state-law defenses to the release, we concluded that the release was not the product of duress and that Santa Fe should not be estopped from asserting its validity. Id. at 568-70. We nevertheless decided to remand the ease for a determination of whether Pierce’s consent to the release was knowing and voluntary and thus sufficient to waive his federal statutory rights. As noted above, we held that the question whether a waiver of ADEA rights was knowing and voluntary should be answered by looking to the totality of the circumstances. Because we were “explicitly adopting this approach for the first time,” we believed that “the trial judge, and possibly a new jury,” should have an opportunity to apply the totality-of-the-circumstances test we had just adopted. Id. at 572. A second jury has now done so, and Santa Fe appeals the result.
On this second appeal, the railroad takes issue with the district court’s entire approach to the proceedings below. More specifically, Santa Fe argues, first, that the district court erred by placing upon the company the burden of proving that Pierce’s consent to the release was knowing and voluntary. Santa Fe also objects to several of the court’s evi-dentiary rulings, many of which, in the company’s view, improperly permitted Pierce to relitigate his discrimination claims and to argue, in disregard of our holding that the release was clear and unambiguous, that he did not understand the terms of the release.
II.
We
first address Santa Fe’s contention that the district court erred in placing upon the railroad the ultimate burden of proving that Pierce’s waiver was knowing and voluntary. The debate centers around one sentence in our first opinion — our direction to the district court that “after the employer raises the existence of a release as a defense to a discrimination suit, the burden rests on the plaintiff to challenge specifically his voluntary and knowing consent to the release,”
The parties can find little support for their respective positions in the opinions of our fellow courts of appeals. Although several courts have explored the factors to be eonsid-ered in determining whether a waiver of an ADEA claim was knowing and voluntary, few have explicitly discussed the proper allocation of the burden of persuasion. 4 This silence may be attributable to the fact that few courts, if any, have had to confront the unusual posture in which Pierce’s claim stood on remand. Pierce already had proved his discrimination claim; the sole issue in the second trial was whether his release was knowing and voluntary under the totality-of-the-circumstances test set forth in our first opinion.
Consequently, the answer to the question posed by Santa Fe’s second appeal is not immediately obvious. Our resolution of the matter, however, will not have long-ranging consequences, for Congress has provided its own answer. Under the 1990 amendments to the ADEA enacted in the Older Workers Benefit Protection Act (“OWBPA”), Pub.L. No. 101-433, § 201, “the party asserting the validity of a waiver shall have the burden of proving in a court of competent jurisdiction that a waiver was knowing and voluntary” based on certain statutory criteria.
See
29 U.S.C. § 626(f)(3).

Congress was equally
A little history puts our prior decision in context and goes a long way toward answering the question posed by Santa Fe’s appeal. For a time, it was not certain that unsupervised waivers of ADEA rights (i.e., waivers executed without the participation of the EEOC) should be valid under any circumstances. The ADEA incorporates enforcement and damages provisions of the Fair Labor Standards Act (“FLSA”),
see
29 U.S.C. § 626(b), and it was arguable that the ADEA, like the FLSA, should be read to prohibit private waivers of the rights it established.
See Runyan v. National Cash Register Corp.,
At the other extreme from a rule that invalidated all privately executed waivers of ADEA claims is an approach that deems all such waivers effective provided they satisfy the state-made law of contracts. In our first opinion, we noted that some circuits, while acknowledging their responsibility to determine that waivers are knowing and voluntary, nevertheless purport to apply only “general principles of contract construction” in making this determination.
See
For this reason, we declined in our earlier opinion to limit the inquiry into knowledge and voluntariness to whether the waiver met the requirements of a valid contract. We joined those circuits which look to the “totality of the circumstances” surrounding the execution of a waiver — an approach we deemed “consistent with the strong congressional purpose underlying the ADEA to eradicate discrimination in employment.”
We have paused to recount this history because the dispute over who should bear the burden of proof on the issue of knowledge and voluntariness implicates some of the same considerations that guided us in adopting the totality approach. On the one hand, it is clear that waivers of ADEA claims are not void as against public policy. It follows that we should be careful not to create a legal environment in which it becomes so difficult for employers to establish the validity of waivers that they cease to have value. With the proper safeguards in place, private settlements are advantageous to employer and employee alike. For both parties, they eliminate the uncertainty and cost of protracted litigation, and, for employees, they promise speedy redress of grievances— a consideration of no small importance in the context of the ADEA. Waivers will no longer be valuable, however, if employees, by repudiating them, can deny employers the benefit of freedom from litigation for which they have bargained. To place upon the employer the burden of demonstrating that an otherwise unambiguous release of claims was not signed knowingly and voluntarily risks undermining the usefulness of waivers by clouding them in uncertainty. This danger is compounded by the difficulty of demonstrating that someone’s actions were knowing and voluntary, an assumption about human behavior which the law typically indulges as a matter of faith.
This line of reasoning has force. Though it gives us pause, we believe that the concerns it reflects are adequately addressed by placing the burden of production, rather than the burden of proof, on the party who, like Pierce, seeks to invalidate a waiver of federal rights. As we noted in our first opinion, such a rule does not mean that a claim that a
This conclusion is consistent with the language of our original opinion, which instructed that “after the employer raises the existence of a release as a defense to a discrimination suit, the burden rests on the plaintiff to challenge specifically his voluntary and knowing consent to the release.” Id. at 572. The term “challenge” suggests only an initial attack, an invitation to defend, but not ultimate victory. More equivalent to a burden of proof or persuasion is a requirement that a party, “demonstrate” or “establish” a proposition. In our previous opinion, moreover, both the majority and the dissent noted without disapproval that, during the first trial, the district court placed upon Santa Fe the burden of demonstrating that Pierce knowingly and voluntarily executed the release.
We observe, finally, that placing the burden of proof upon Santa Fe with respect to whether Pierce knowingly and voluntarily waived his ADEA claims is consistent with our holding that waivers of federal rights cannot be governed solely by principles of contract — a holding that stems from the view that “[wjaivers of federal remedial rights ... are not lightly to be inferred,”
Torrez v. Public Service Co. of New Mexico,
III.
Santa Fe also maintains that the district court erred in denying its motion for judgment as a matter of law following the jury’s verdict. Our review of the district court’s ruling on Santa Fe’s motion is
de novo,
but limited to a very narrow scope.
See Emmel v. Coca-Cola, Bottling Co.,
Pierce approached Pacocha about obtaining a 360 severance package after he learned that other employees had received the package. Pacocha and Leighton Broxterman, the employee who authorized the deal, both testified that when they decided to offer Pierce the package they did not know that he had filed age and race discrimination claims with the EEOC. When Pierce initially asked Pa-coeha whether the release would cover discrimination claims, Pacoeha’s response, according to the testimony of both Pierce and Pacocha, was that Pacocha did not believe so but would check. Beyond this point of agreement, the stories diverge: Pierce testified that Pacocha subsequently confirmed that the release would not bar Pierce’s discrimination claims, while Pacocha and a Santa Fe employee who witnessed the second meeting testified that Pacocha told Pierce just the opposite.
The jury was entitled to credit Pierce’s testimony over Paeocha’s. After deciding to credit Pierce’s version of events, it would have been difficult for the jury to conclude that the waiver was knowing and voluntary.
See K.M.C. Co.,
Finally, there is the matter of consideration. After learning that his department would be moving from Illinois, Pierce sought and obtained the severance package in connection with which he received $36,000 and signed the release that is the subject of this appeal. Although Santa Fe insists that Pierce “was not at all entitled to this amount by law or even by past practice,” the testimony of Pacocha and Broxterman suggests that this representation does not paint a complete picture. Under the collective bargaining agreement in place at the time, an employee who did not wish to relocate to a new work-site had the right to “bump” a less senior employee, that is, to take his or her job. This process might continue until an employee at the bottom of the pecking order was without a position, in which case the unlucky employee would be furloughed. Santa Fe, however, remained obligated to pay wages and benefits to protected union employees on furlough until the company could find them new employment.
11
The package that Pierce received was generally offered to employees in exchange for an' end to their right to continue receiving payments and benefits from Santa Fe; approximately 20 employees had accepted the package during the summer of 1989. Thus, although Santa Fe voluntarily offered such packages, the packages served to extinguish obligations arising under the union contract. Pacocha and Broxterman pointed to these considerations in explaining the decision to offer a severance package to Pierce. As Broxterman testified, “It meant that we could either reduce a position or return somebody from a furlough status.”
12
Santa Fe points out that the severance package was conditioned on Pierce’s signing the release. Indeed, Broxterman testified that every employee receiving a severance package was required to execute a release. But a company’s conditioning of all severance packages upon the signing of a general release of any and all claims cannot defeat the inquiry in a particular case into whether the waiver of statutory rights was knowing and voluntary. It must be remembered that our inquiry is not whether there was consideration adequate to support the release; if there were none, the release would fail as a matter of contract, and the knowing-and-voluntary test would be unnecessary. Rather, the question is whether Pierce’s waiver of his rights was knowing and voluntary under the totality of the circumstances. In that regard, the existence of a future obligation that was extinguished in exchange for the extension of a standard severance package stands as merely one piece of objective evidence tending to support Pierce’s claim that he was subjectively unaware that he was waiving important statutory rights.
13
It may have been the case— indeed it appears certain — that Santa Fe would not have granted Pierce the severance package without his signing the release. Yet under the circumstances described by Brox-terman and Pacocha, it would have been possible for Pierce to conclude that the release did not constitute a central component in the bargain. If, for example, the waiver had entitled Pierce to the more generous of two severance packages, it would be less plausible for him to argue that he did not appreciate the gravity of the document he executed.
Cf. Gormin v. Brown-Forman Corp.,
We have stressed the above factors, not because any one of them is dispositive, but because the jury was entitled to consider them. Had the jury found in favor of Santa Fe, we would be able to point to factors supporting that verdict. Had the members of this panel sat as jurors, we might have interpreted the facts differently. Our role, however, is not to reweigh the evidence, but only to ensure that the jury rationally considered the evidence. We are satisfied Santa Fe was not entitled to judgment as a matter of law.
IV.
Santa Fe also complains of certain evidentiary rulings by the trial court, fore
Santa Fe misapprehends the nature of the totality-of-the-circumstances test. The inquiry into whether a waiver of ADEA rights was knowing and voluntary is, at bottom, an inquiry into the mental state of the party who is purported to have waived those rights. This is the rationale behind our rejection of pure contract analysis in favor of the totality approach. In order to protect truly voluntary bargains, we do not permit claims of subjective misunderstanding, standing alone, to defeat an otherwise valid release; but the totality approach permits the introduction of evidence, beyond that which could be considered for the purposes of interpreting a contract, from which the jury may infer that the releasor did not, in fact, understand the legal consequences of his actions. This court’s rejection of Pierce’s contract-law defenses is therefore beside the point. See
Santa Fe also contends that the district court abused its discretion in admitting evidence of Pierce’s underlying discrimination claims and of the humiliation he felt at having been demoted to file clerk. The sole issue upon remand, the railroad argues, was the execution of the release; the introduction of events relating to Pierce’s age and race discrimination claims, many of which occurred months earlier, served only to prejudice the jury against Santa Fe. We agree that, when the validity of a release is the only question before a jury, trial courts should be exceedingly careful to ensure that underlying claims of discrimination do not cloud the issue. On the facts of this case, however, we
The district court exercised a significant screening function with respect to evidence from the first trial. The court held that the jury would not be informed of its predecessor’s finding in favor of Pierce and instructed the jury on at least two occasions that it was not to consider the merits of Pierce’s discrimination claims. Moreover, the district court did not indiscriminately admit evidence of Santa Fe’s discriminatory conduct. Rather, the guiding principle behind the court’s evidentiary rulings was that Pierce’s “perception of whether he had a valid claim has some relevance to the issue of whether he knowingly and voluntarily released that claim.” The court was careful to limit the evidence to matters of direct knowledge to either Pierce or Pacocha. Thus, for example, the court largely denied Pierce’s request to admit the prior testimony of Steven Mitchell, a Santa Fe official who had been impeached at the first trial in his efforts to bolster Santa Fe’s claim that Pierce had been fired as a result of a carefully considered reduction in force. The court limited the Mitchell testimony to portions dealing with two occasions on which Pierce had raised the issue of Santa Fe’s treatment of its African-American employees. “[T]he rationale on which I believe that [the Mitchell testimony] is admissible,” the court explained, “is that it demonstrates the consistency with which Mr. Pierce asserted his rights and suggests some support for his testimony that he would not have knowingly relinquished his discrimination claims.” Also admissible under the district court’s approach to the second trial was the list of employees on which Pacocha had written the word “risk” next to Pierce’s name. This evidence, after all, tended to undermine Pa-eoeha’s assertion that, when he first presented the release to Pierce, he had not apprised himself of the release’s effect should Pierce file a discrimination suit against Santa Fe.
The district court’s evidentiary rulings reflect a sensible accommodation. The merits of an underlying discrimination claim arguably have little relevance with respect to whether a party’s waiver of that claim was knowing and voluntary. Undeniably relevant to the question of knowing and voluntary waiver, however, is whether the employee has asserted a grievance prior to the execution of a release, and the force with which he has asserted that grievance. When the evidence demonstrates that the waiver of statutory rights was the basis of the bargain between employee and employer, it is logical to infer that the attention of both parties, at the time of negotiations, focused squarely upon the waiver and its implications. For this reason, not all of the evidence of which Santa Fe complains was necessarily unfavorable to the railroad. It was open for the company to argue that Pierce, believing he had a valid discrimination claim against Santa Fe and having demonstrated in the past a willingness to speak out on behalf of minority employees, was unlikely to 'sign away his rights without fully informing himself of the consequences. Although the jury did not draw this inference, the district court’s evi-dentiary rulings nonetheless afforded the jury the context necessary to evaluate the circumstances surrounding Pierce’s consent to the release.
Santa Fe next objects to the district court’s ruling admitting evidence that the company did not bring Pierce’s release to the attention of the EEOC. The argument is that, because Santa Fe was not obligated to raise the release before the EEOC, its failure to do so had no probative value, and evidence on this score could only have prejudiced or confused the jury; such evidence therefore should have been excluded under Rule 403 of the Federal Rules of Evidence. The district court apparently accepted Pierce’s theory that Santa Fe’s failure to raise the release tended to show that the release was a belatedly contrived defense. Though this line of attack may be at odds with Pierce’s suggestion that Pacocha deliberately “sehnookered [Pierce] into signing the release,” there is no requirement that a party adopt a consistent position throughout trial, and it was for Santa Fe to exploit the inconsistency. We do not believe that admission of this evidence constituted an abuse of discretion.
Turning from evidence that

The district court did not abuse its discretion in excluding this evidence. Although Santa Fe may have been surprised by the district court’s change of heart on this issue, the company does not point to any rule of law that would have bound the court to its earlier ruling. Absent such an obligation, we see no abuse of discretion on the part of the district court, which fully explained the reasons behind its change in position. The court noted that, on the authority of

. The district court shared Pierce's reading of our opinion: "The language quoted by the defense from the court of appeals’ opinion at 572 could as easily apply to production burdens or, as the court concludes is more likely, to the issue of when there is sufficient evidence of invalidity to justify submission of the issue to the jury.”
. Although we might have looked for guidance from cases dealing with contractual waivers of the right to jury trial, neither party can find comfort there. The circuits are split on whether the party asserting the validity of such a waiver bears the burden of proof as to whether the waiver was knowingly and voluntarily executed.
See Hulsey v. West,
.Under section 201 of the OWBPA, 29 U.S.C. § 626(f), an employee may not waive an ADEA claim unless the waiver is knowing and voluntary. A waiver will not be considered knowing
(A) the waiver is part of an agreement between the individual and the employer that is written in a manner calculated to be understood by such individual, or by the average individual eligible to participate;
(B) the waiver specifically refers to rights or claims arising under this chapter;
(C) the individual does not waive rights or claims that may arise after the date the waiver is executed;
(D) the individual waives rights or claims only in exchange for consideration in addition to anything of value to which the individual already is entitled;
(E) the individual is advised in writing to consult an attorney prior to executing the agreement;
29 U.S.C. § 626(f)(1). In addition, if the waiver is in settlement of an EEOC charge or a lawsuit filed under the ADEA, the employee must be given "a reasonable period of time within which to consider the settlement agreement.” 29 U.S.C. § 626(f)(2). If not in settlement of such a suit, the waiver is valid only if the employee is provided 21 days within which to consider the agreement (45 days "if [the] waiver is requested in connection with an exit incentive or other employment termination program offered to a group or class of employees”) and is permitted to revoke the waiver within seven days following its execution. 21 U.S.C. § 626(f)(1)(F), (G).
. Santa Fe asserts, without citation to any authority, that "to the extent that OWBPA sheds light on this matter, it simply documents that, ■ prior to the Act, the burden was properly placed on the Plaintiff." Practitioners appear to be of two minds, however, with respect to whether or not the OWBPA merely codified the common-law burden of proof. Compare Joel L. Finger, Selected Topics in Age Discrimination Litigation, 299 Prac.L.Inst./Lit 9, 12 (1986) ("Under federal common law, the defendant typically bears the burden of proving that the release was knowingly and voluntarily entered into ...."), with B. Scott Silverman, Enforceability of Releases and Arbitration Agreements in Individual Employment Discrimination Cases, C742 A.L.I.-A.B.A. 1091, 1099 (1992) ("The statute reverses the old burden of proof and places upon the employer the burden of proof in litigation to establish that the waiver was voluntary and knowing.”).
. As noted above, Congress, in the OWBPA, ultimately endorsed the judicial consensus regarding the enforceability of unsupervised releases, although in 1989 it considered a proposed statute, The Age Discrimination in Employment Waiver Protection Act of 1989, that contained restrictions on the use of such waivers. See Sen.Rep. No. 101-79. The OWBPA rejected these restrictions in response to the EEOC’s fear "that it lacked the resources or capability to supervise releases.” See Sen.Rep. No. 101-263, at 32. The OWBPA's carefully drawn waiver requirements nevertheless reflect the policy concerns underlying the earlier proposal. See id. at 15 ("|T]he substitute waiver provisions included as Title II of this bill [the OWBPA] differ from ... [the Waiver Protection Act]. Nonetheless, the need for such legislation has been fully explained in our earlier report, and — to the extent it is-consistent with Tide II — -we adopt that earlier discussion by reference.”).
. Of course, it could be objected that, although absence of fraud is, in a sense, a prerequisite to the validity of any contract, fraud is nevertheless an affirmative defense which the party seeking to avoid a contract must establish. This objection, however, carries force only if one conceives of the employer’s waiver defense purely as an attempt to enforce a contract. Our adoption of the totality-of-the-circumstances test stemmed from a recognition that the inquiry into knowledge and voluntariness “cannot end” with the plain language of the contract.
See
. Santa Fe also points to language in our original opinion stating that “Pierce should have understood the meaning of the agreement,” and that “Pierce’s reliance was unreasonable as a matter of law.”
. On direct examination, Pierce's response to the question “what conclusion did you draw [after talking to the EEOC investigator]?” suggested that the investigator indicated to Pierce that the release would not bar his claims. This circuitous mode of questioning was necessitated by the mistaken belief that the EEOC investigator's response was hearsay. Hearsay is an out-of-court statement "offered in evidence to prove the truth of the matter asserted." Fed.R.Evid. 801(c). Because the correctness of the investigator’s response mattered not a whit, but was introduced only to establish Pierce's state of mind, the response was not hearsay.
. Broxterman testified that protected union employees on furlough were entitled to payments and benefits until the age of 70.
.Pacocha explained, “I pointed out to Mr. Broxterman that Gene [Pierce] had approached me and asked for a severance, that we had a number of people that we would wind up giving a severance to because of the particular geographic location they were in. And since Gene had asked and he obviously wanted to leave the company, other people may not want to leave the company but be forced into it, I thought it would be a good thing to do to make Gene happy and to make somebody else happy by giving Gene a severance." In response to the follow-up question, “So if it wasn't given to him and he bumped, somebody else would be bumped and you would end up giving the severance to them?” Pacocha testified, "Right. We were giving one to somebody, and Gene had asked for it or had asked me to look into it, and so I mentioned to Leighton that this looked like something that was
. It is significant, therefore, that Pierce apparently was not told, in connection with the severance offer, that an exception to general practices was being made on his behalf.
. The district court thus properly rejected Santa Fe’s request for the following jury instruction: “I further instruct you that the language of the release is, as a matter of law, clear and unambiguous and covers the claims Plaintiff seeks to assert. You should disregard any contention or argument that Plaintiff did not understand this fact or that the release is capable of some other interpretation.” Our remand would appear whimsical indeed if it prescribed such a meaningless exercise.
