OPINION OF THE COURT
This еmployment discrimination case, arising under the Age Discrimination in Employment Act (“ADEA”), 29 U.S.C. § 621 et seq., presents a question of admissibility under Federal Rule of Evidence 404(b) of a subsequent good act offered by an employer to demonstrate non-discriminatory intent-namely, the employer’s favorable treatment of another older worker. Plaintiff Harry Ansell, who was 45 years old, was terminated by his supervisor, Douglas Schiff, at Green Acres Contracting Company, Inc. (“Green Acres”). Several seasons later, Schiff hired an employee who was the same age as Ansell. Ansell argues that the evidencе of this subsequent hiring is irrelevant to his employer’s intent as a matter of law. He also argues that evidence of the subsequent act was admitted for an improper purpose and that its unfair prejudice substantially outweighed its probative value. Because we conclude that the evidence was relevant and admitted for a proper purpose, and because its probative value was not substantially outweighed by unfair prejudice, we will affirm the judgment of the District Court.
I.
Green Acres performs highway maintenance work on a seasonal basis. Harry Ansell workеd as a laborer and truck driver for Green Acres during each season from 1993 until 1997. At the beginning of the 1997 season, Ansell was assigned to a five person crew led by a new foreman, Douglas Schiff. Ansell was permanently laid off in December of 1997.
Ansell filed suit in April of 1999 against Green Acres, Schiff, Green Acres’ Vice President Paul Humberston, and Green Acres’ President Thomas Pisula (collectively “defendants”), seeking damages for discharge in violation of the ADEA and the Pennsylvania Human Relations Act (“PHRA”), 43 Pa. Con. Stat. Ann. § 951 et seq. 1 According to Ansell’s theory of the case, Schiff sought to increase his crew’s productivity by rеplacing the older members of his crew with younger workers. At trial, Ansell introduced testimony establishing that Schiff permanently laid off two truck driver/laborers on his crew. In July of 1997 Schiff replaced Roger Myers, age 47, with Scott Miller, age 26, and in December of 1997, Schiff replaced Ansell with Harry Fabian, Jr., age 28. Schiff also hired an additional worker in his twenties, Keith Summers, in July 1997 around the same time he hired Scott Miller.
Defendants responded that Schiff had legitimate, nondiscriminatory reasons for terminating Ansell and offered evidence of four incidents of insubordination involving Ansell. First, in late July of 1997, Ansell insisted that he should be аssigned to drive the crew truck based on his seniority, and swore at Schiff when Schiff disagreed. Then in December, Ansell argued *519 with a state inspector about a stop and go paddle used for traffic control, refused to attend a safety meeting, and took time off from work, without permission, to go hunting.
Defendants also presented evidence regarding Schiffs treatment of employees over the age of forty. Specifically, defendants presented the testimony of Anthony Beddingfield, who, at age 45, was hired by Green Acres in August of 1999 for a temporary laborer position and assigned to Schiffs crew. Beddingfield testified that he was asked by Schiff to stay on the crew permanently, and that he was still working for Schiff at the time of trial in 2002.
Ansell filed a motion in limine objecting to any testimony by Beddingfield concerning his hiring and treatment by Schiff. 2 Ansell argued that this testimony was inadmissible “other acts” evidence, offered to show propensity under Federal Rule of Evidence 404(b). Ansell further argued that Beddingfield’s testimony was not relevant and was unfairly prejudicial. Defendants proffered that Beddingfield’s testimony was admissible to show that Schiff lacked an intent to discriminate against older workers. The District Court denied Ansell’s motion, declaring that Bedding-field’s employment was probative of Schiffs intent and that it was admissible under Rule 404(b). The District Court noted that Ansell had introduced evidence of numerous people under age 40 hired by Green Acres after Ansell was fired, and stated that “if that’s 404(b) evidence [of intent], so is this other witness.”
The ADEA and PHRA claims were tried before a jury, which returned a verdict in favor of the defendants on July 18, 2002.
3
Ansell appealed, challenging only the District Court’s decision to admit the Beddingfield testimony under Rule 404(b). We have jurisdiction over Ansell’s appeal pursuant to 28 U.S.C. § 1291.

We exercise plenary review over the District Court’s interpretation of the rules of evidence; however, assuming that the evidence could be admissible in some circumstances, we review the District Court’s decision to admit that evidence for abuse of discretion.
United States v. Givan,
II.
Federal Rule of Evidence 404(b) states, in pertinent part:
*520 Other Crimes, Wrongs, or Acts.-Evidence of other crimes, wrongs, or aсts is not admissible to prove the character of a person in order to show action 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 ...
Rule 404(b) thus prohibits the admission of other acts evidence for the purpose of showing that an individual has a propensity or disposition to act in a particular manner.
Gov’t of the Virgin Islands v. Pinney,
The typical Rule 404(b) case presents a prosecutor in a criminal case seeking to introduce evidence of prior bad acts of a defendant. If the purpose of the evidence is to show that the conduct charged was not performed inadvertently, accidentally, or without guilty knowledge and intent (that is, for one of the specific permissible uses outlined in Rule 404(b)), it is admissible.
See, e.g., Givan,
For other acts evidence to be admissible under the exceptions listed in Rule 404(b), (1) the evidence must have a proper purpose; (2) it must be relevant under Rule 401 and 402; (3) its probative value must outweigh its prejudicial effect under Rule 403; and (4) the court must charge the jury to consider the evidence only for the limited purpose for which it was admitted.
United States v. Sampson,
A.
To be admissible under. Rule 404(b), other acts evidence must be offered for a proper purpose,
i e.,
a purpose other than showing that an individual has a propensity or disposition for certain activity.
Pinney,
The District Court ruled that Bedding-field’s testimony was offered to establish that Schiff did not have a discriminatory intent when he discharged Ansell, intent being an enumerated proper purpose under Rule 404(b). Ansell contends that Beddingfield’s testimony was not evidence of intent, but rather was evidence of Schiff s good character or propensity not to discriminate against older workers, introduced to show that he acted “in conformity therewith” when he fired Ansell. As such, Ansell argues that Beddingfield’s testimony is classic propensity evidence that is inadmissible under Rule 404(b).
The nature of the underlying case illustrates the true purpose of Beddingfield’s testimony. At trial, the parties did not dispute that Ansell made out a prima facie case of age discrimination under the ADEA. Likewise, there was no dispute that Green Acres advanced a legitimate, nondiseriminatory reason for its decision to fire Ansell. Accordingly, the sole question for the jury was whether the legitimate reason advanced by Green Acres was the true reason for the termination, or whether that reason was simply a pretext for unlawful discrimination.
See generally Keller v. Orix Credit Alliance, Inc.,
Evidence of an employer’s conduct towards other employees has long been held relevant and admissible to show that an employer’s proffered justification is pretext.
See, e.g., McDonnell Douglas Corp.,
The District Court admitted evidence offered by Ansell showing that Green Acres hired numerous individuals under the age of 40 after Ansell was fired. In his closing argument, Counsel for An- *522 sell read the court’s instruction on pretext back to the jury and then argued:
Production evidently does not improve for Doug Schiff, and what is Doug Schiffs first move? What does he do? He fires Roger Myers. He fired Roger Myers, who, at that time, was 47....
Who does Doug Schiff replace Roger Myers with? Scott Miller. Age twenty-six. Scott replaces Roger, and then he also hires Keith Summers, who was age twenty-five.
Counsel for Ansell concluded:
And I submit to you that Doug had accomplished what he set out to do. He accomplished getting rid of the older workers to increase productivity. And you could see the difference in the ages. You could see from Kevin and Keith, the difference in the young worker. That’s what Doug wanted. Doug wanted to get younger guys. He wanted them, and he thought that was going to correct his production problems.
When we talked in openings - when I talked to you in opening statements, I said in discrimination cases, actions speak louder than words. Well, what are Doug Schiffs actions? He got rid of the older workers and he replaced them with the younger ones.
Beddingfield’s testimony was offered to rebut Ansell’s argument that his termination was motivated by an overarching plan to eliminate older workers, and to corroborate defendants’ evidence of a legitimate, nondiscriminatory reason for An-sell’s termination. In her proffer, counsel for defendants explained: “[Counsel for Plaintiff] has tried to show discriminatory intent by showing how [Schiff] treated one other individual over forty; that is, Roger Myers. So, we should be permitted to respond to that by showing intent with another employee over forty.” And in its closing argument, counsel for defendants stated: “If [Schiff] didn’t want guys on his crew who were over forty, why did he talk to Tony Beddingfield to stay on? [D]oes it show an intent to create a youth movement? Does it show an intent to design this crew that’s all young men or women? No.”
The evidence offered by both defendants and Ansell was not predicated upon an inference that Schiff had a propensity to act in a certain way. Indeed, Schiffs
actions
were never in disрute. Rather, the sole question was Schiffs intent when he acted, or, more precisely, whether the reason offered by Schiff was pretextual.
See, e.g., Heyne,
The principal case on which Ansell relies illustrates this distinction. In
Becker,
an ADEA plaintiff introduced evidence that his employer had previously asked him to fabricate a reason to terminate another worker.
Here, defendants introduced into evidence the fact that Beddingfield was 45 years old when Schiff asked him to stay on with the crew. This evidenсe thus purported to rebut Ansell’s theory that he was fired as part of a broader plan to “get[] rid of the older workers to increase productivity,” and to support the legitimate reason advanced by defendants for the termination. We conclude that Bedding-field’s testimony was admitted for the proper purpose of establishing Schiffs intent when he terminated Ansell.
B.
Evidence is relevant if it makes “the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” Fed.R.Evid. 401. As discussed above, evidence regarding an employer’s treatment of other members of a protected class is especially relevant to the issue of the employer’s discriminatory intent.
Becker,
Ansell nevertheless argues that Schiffs treatment of Beddingfield in 1999 is not relevant to Schiffs intent when terminating Ansell because the treatment was favorable and occurred several years after Ansell’s termination, at a time when productivity was no longer an issue. Based on these distinctions, Ansell suggests that Schiffs treatment of Beddingfield did not make it any more or less probаble that Schiff was acting with discriminatory intent when firing Ansell. 6
Ansell cites no authority for the proposition that an employer’s favorable-as opposed to discriminatory-treatment of other
*524
employees is irrelevant to intent. Nor does Ansell offer any reason why favorable treatment would not make the presence or absence of discriminatory intent “more probable or less probable.” Instead, An-sell cites cases holding that a defendant employer is not entitled to dismissal or summary judgment simply because it has treated other members of the protected class favorably.
E.g., Connecticut v. Teal,
Ansell further argues that Schiffs treatment of Beddingfield in 1999 is too remote to be relevant to the question of Schiffs discriminatory intent when he fired Ansell in 1997. According to Ansell, Schiff sought out a younger workforcе in 1997 in response to productivity concerns raised that year. According to Ansell, Schiffs actions vis-a-vis Beddingfield twenty months later were not relevant as a matter of law because they were too far removed in time, and occurred when productivity was no longer a concern.
Subsequent actions by an employer against co-workers may be less probative of an employer’s intent than prior actions “because the logical relationship between the circumstances ... and the employer’s decision to terminate is attenuated.”
Coletti,
There is, however, no bright line rule for determining when evidence is too remote to be relevant.
See, e.g., United States v. Pollock,
C.
Federal Rule of Evidence 403 states that “[although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice.” A district court’s explicit balancing analysis under Rule 403 should only be disturbed if it is “irrational or arbitrary.”
Abrams,
Ansell claims that the danger of unfair prejudice outweighed the probativе value of the subsequent acts evidence provided by Beddingfield. He argues that the probative value of the evidence was minimal because of its remoteness in time and the changed circumstance, and that such probative value was outweighed by the prejudice arising from the admission of this evidence since it changed the outcome of the case and resulted in a verdict in favor of defendants. However, “[prejudice does not simply mean damage to the opponent’s cause.”
Goodman v. Pa. Turnpike Comm’n,
[T]he ... prejudice against which the law guards [is] ... unfair prejudice- ... prejudice of the sort which cloud[s] impartial scrutiny and reasoned evaluation of the facts, which inhibits] neutral application of principles of law to the facts as found.... [Prejudice does not simply mean damage to the opponent’s cause. If it did, most relevant evidence would be deemed prejudicial.
Id. (internal quotations omitted).
Unfair prejudice under Rule 403 could arise if a jury uses 404(b) evi
*526
dence to infer propensity rather than intent.
See Robert S. v. Stetson School, Inc.,
Ansell also suggests that he was unfairly prejudiced because the admission of evidence of Schiffs treatment of Beddingfield improperly indicated to the jury that Ansell had to prove that Schiff was still discriminating several years later. We can conceive of no way the jury reasonably could have concluded that continuing discrimination was an element of the plaintiffs case. Certainly, the jury was not instructed that continuing discrimination was part of the plaintiffs burden of proof, nor did counsel argue any such theory of the case.
Ansell has not demonstrated unfair prejudice arising from Beddingfield’s testimony. Thus, it was impossible for the probative value of this evidence, even if minimal, to be substantially outweighed by unfair prejudice.
III.
In the end, we return to the fact that “[t]he drafters contemplated that Rule 404(b) would be construed as a rule of ‘inclusiоn’ rather than ‘exclusion.’ ”
United States v. Scarfo,
Notes
. Ansell also claimed damages under the Americans with Disabilities Act ("ADA”). 42 U.S.C. § 12101 et seq., and Rehabilitation Act of 1973 ("Rehab Act”), 29 U.S.C. § 701 et seq, but the District Court granted a motion by defendants for summaty judgment on these claims. Ansell did not appeal this ruling.
.Ansell did not object to testimony presented by defendants regarding John Bradley, another member of Schiff's crew over the age of forty. Bradley was a flagger who was kept on until the end of the 1997 season. When the 1998 season began, Bradley did not resume work at Green Acres because he had taken a job closer to home. However, defendants' evidence showed that, in June 1998, Bradley called Schiff to ask for a job and was rehired to work on Schiff’s crew for the entire season. Bradley himself testified that, as a worker over 40, he was well treated by Schiff. With the Bradley evidence having been admitted without objection, defendants argue that any error with respect to Beddingfield’s testimony is harmless. Because we affirm the District Court’s decision to admit the Beddingfield testimony, we do not reach this issue.
. A prior trial in April 2001 resulted in a mistrial due to a hung jury.
. The District Court had jurisdiction over the ADEA claim pursuant to 28 U.S.C. § 1331, and exercised supplemental jurisdiction over the PHRA claim pursuant to 28 U.S.C. § 1367.
. The other cases relied on by Ansell,
Neuren v. Adduci, Mastriani, Meeks & Schill,
In
Neuren,
the employer claimed that it terminated plaintiff for failure to meet deadlines and introduced evidence that the plaintiff had experienced similar performance problems with another employer.
. Ansell’s trial counsel noted in his cross-examination of Beddingfield and his closing argument that Schiff’s subsequent hiring of Beddingfield occurred three months after Schiff was served with notice of Ansell’s lawsuit. Ansell does not suggest on appeal that this affected the relevance of that subsequent hiring. We thus have no reason to consider in this appeal whether actions taken by an employer after he becomes aware of a discrimination suit can have any bearing on that employer’s intent at the time of the adverse employment action.
. Fed.R.Evid. 105[ ] provides that the trial court shall, upon request, instruct the jury that the similar acts evidence is to be considered only for the proper purpose for which it was admitted.”
