    Appellant,
    vs.
    SWIFT PORK COMPANY, TROY MULGREW, and TODD CARL,
    Appellees.
    On review from the Iowa Court of Appeals.
    Appeal from the Iowa District Court for Marshall County, Bethany Currie,
    Judge.
    Defendants seek further review of the decision of court of appeals that
    reinstated the plaintiff’s age discrimination claim dismissed on summary
    judgment. DECISION OF COURT OF APPEALS AFFIRMED IN PART AND
    VACATED IN PART; DISTRICT COURT SUMMARY JUDGMENT AFFIRMED.
    Waterman, J., delivered the opinion of the court, in which all participating
    justices joined. May, J., took no part in the consideration or decision of this case.

    WATERMAN, Justice.
    The plaintiff, age sixty, texted his plant manager “FUCK You!” and “Believe
    who and what you want” shortly after that manager harshly criticized his job
    performance. The plaintiff was promptly fired, and he sued for wrongful
    termination, workplace harassment, and age discrimination. The defendants
    moved for summary judgment on the grounds that this at-will employee was
    lawfully fired for insubordination. The plaintiff resisted, arguing that he meant
    to text someone else, the defendants retaliated against him for making safety
    complaints, profanity was widespread at this workplace, and the employer had
    a practice of discriminating against older employees. The district court granted
    summary judgment, dismissing all claims, and we transferred the plaintiff’s
    appeal to the court of appeals, which affirmed two counts but reinstated the age
    discrimination claim, determining questions of fact precluded summary
    judgment. We granted the defendants’ application for further review.
    On our review, we determine that the district court properly granted
    summary judgment on all claims. We modify the McDonnell Douglas
    burden-shifting framework for summary judgment on discrimination claims
    under the Iowa Civil Rights Act (ICRA) to align with the causation standard at
    trial.1 We adopt and apply the good-faith “honest belief rule”2 to affirm the
    employer’s decision to terminate the plaintiff for insubordination. The employer’s
    investigation was adequate. While there is a culture of profanity at the

    meatpacking plant, no other employee texted or said “FUCK You!” to the plant
    manager right after his negative performance review. While the plaintiff named
    other older employees who had been terminated over several decades, he had no
    direct evidence or any expert statistical analysis to show a company practice of
    discriminating against older workers. We hold this plaintiff lacked proof
    sufficient to raise a jury question on age discrimination.
    I. Background Facts and Proceedings.
    We review the record in the light most favorable to the plaintiff. David Alan
    Feeback worked for Swift Pork Company (Swift) for nearly thirty years, beginning
    in 1988 as a production worker at its Marshalltown pork processing plant. He
    rose through the ranks and ultimately was promoted to a middle management
    position there as cut floor supervisor. He held that position in 2015 at age sixty.
    Feeback was an at-will employee with no employment contract. He received
    mostly positive employment reviews through 2014. He received a raise and
    bonus in 2015.
    In May 2015, Feeback complained to his direct supervisor, Todd Carl,
    about unsafe working conditions on the cut floor. Feeback reported the trolleys
    that transported hog carcasses from coolers to the cut floor were old and worn
    out, and their poor condition allowed carcasses to slide off. Feeback warned that
    workers could be injured by a falling carcass. Carl responded by emphasizing
    high replacement costs and abruptly ended their conversation. When Feeback
    raised the issue again in a phone call a few weeks later, Carl hung up
    mid-conversation. Although Feeback did not raise that safety issue again, their
    4
    conflict broadened to other issues. Carl accused Feeback of being “asleep at the
    wheel” and letting his department run “out of control.” Troy Mulgrew, Swift’s
    general manager, also displayed hostility. Mulgrew once interrupted Feeback’s
    bathroom break, accusing him of “fucking around” in there. In early December,
    Mulgrew reprimanded Feeback for missing a safety meeting; Carl said nothing
    in Feeback’s defense even though Carl had approved Feeback’s absence.
    Their conflict came to a head on December 31. Feeback scheduled a safety
    meeting for that afternoon because his department had not completed its
    required annual safety training. Swift usually let employees go home early on
    New Year’s Eve. Mulgrew pulled rank, called off the safety meeting, sent the
    employees home for the holiday, and summoned Feeback and Carl to his office.
    Mulgrew criticized Feeback at length. Mulgrew emphasized that Feeback’s
    department had the highest absenteeism rate; Feeback replied that his
    department also had the lowest turnover rate. Mulgrew told Feeback that he
    should be listening with his “mouth shut and his arms open.” Mulgrew said
    another employee quoted Feeback as saying Mulgrew was the worst manager
    Feeback ever had. Feeback said nothing more, and the meeting ended.
    Later that evening, at 5:42 p.m., Feeback sent two text messages to
    Mulgrew. The first said, “FUCK You!” The second said, “Believe who and what
    you want.” Feeback did not follow up with any text or other communication
    apologizing or claiming he sent Mulgrew those texts by mistake. Before that New
    Year’s Eve, the last time Feeback had texted Mulgrew was September 15.
    5
    That same evening, Mulgrew sent a screenshot of Feeback’s messages to
    Pete Charboneau, Swift’s HR Director, and to Carl. Charboneau interviewed
    Feeback the next morning. Feeback admitted that he sent the texts to Mulgrew
    but contended “it was by mistake” and that he meant to send those texts to a
    friend instead. Charboneau asked Feeback why, if that was the case, he did not
    rescind the messages or contact Mulgrew to explain and apologize. Feeback
    replied that he did not know how to rescind a text and hadn’t seen Mulgrew yet
    that morning to explain. Charboneau suspended Feeback on the spot and
    continued his investigation.
    On January 4, 2016, Swift terminated Feeback’s employment. According
    to Charboneau, Feeback was fired because of the offensive text he sent Mulgrew.
    Meanwhile, Swift had already begun replacing the old trolleys, addressing the
    safety issue that Feeback raised earlier. At this time, Swift’s Marshalltown facility
    employed more than 100 individuals who were age sixty or older. Feeback would
    have been eligible to retire within two years. Swift filled his position with another
    longstanding employee, a fifty-year-old man.
    Feeback sued Swift, Mulgrew, and Carl (collectively Swift) alleging age
    discrimination, retaliation, workplace harassment, and wrongful termination in
    violation of public policy. At his deposition, Feeback admitted that he sent the
    inappropriate text messages to Mulgrew on New Year’s Eve but asserted they
    were meant for a friend. Feeback admitted that he never re-sent the messages to
    that friend. He never provided any context to explain why he meant to text those
    words to his friend. He also admitted that he had no personal knowledge that
    6
    any other Swift employees had been terminated because of their age. He never
    claimed anyone at Swift mentioned his age in connection with his termination or
    job performance.
    Feeback subsequently withdrew his retaliation claim. Swift moved for
    summary judgment on his three remaining claims. In resisting the motion,
    Feeback submitted an affidavit that included a list of Swift employees over the
    age of fifty-five who had been terminated, demoted, or forced out since 1994 and
    a list of employees who had used profanity at Swift. The district court granted
    summary judgment in favor of Swift on all claims. The district court determined
    that his evidence of workplace harassment—negative comments by Carl and
    Mulgrew—was insufficient to show a hostile work environment. The district court
    concluded that Feeback’s claim of wrongful discharge in violation of public policy
    failed because he lacked evidence that his safety complaints were a determinative
    factor in his discharge. The court noted Feeback’s last complaint about the
    trolley was seven months before his termination and Charboneau was unaware
    of Feeback’s safety complaints.
    Addressing the age discrimination claim, the district court noted that
    “Mr. Feeback has offered no direct evidence of discrimination” and “does not
    allege that he was ever subjected to any age-related comments.” The court
    observed Feeback relied “on indirect evidence of discriminatory motive.”
    Accordingly, the court applied the McDonnell Douglas burden-shifting analysis
    on summary judgment. The court assumed based on his age, job qualifications,
    and termination that Feeback met his initial burden to make “out a prima facie
    7
    case of age discrimination.” Next, the court determined that “Swift articulated a
    legitimate, nondiscriminatory reason for Mr. Feeback’s termination: misconduct
    for swearing at a supervisor via text message.” The district court reviewed the
    record, including evidence of profanity of other employees and older workers who
    had been demoted or terminated. The court concluded that Feeback “failed to
    present sufficient evidence from which a reasonable jury could infer that Swift’s
    legitimate, nondiscriminatory reason for termination was pretextual and age
    discrimination was Swift’s actual reason for termination.”
    Feeback appealed, and we transferred the case to the court of appeals,
    which affirmed summary judgment on his claims for workplace harassment and
    wrongful termination in violation of public policy. The court of appeals reversed
    summary judgment on the age discrimination claim, concluding that a genuine
    issue of material fact existed about “who[m] Feeback meant to text” and that
    inferences of discrimination arose from the brevity of Swift’s investigation, the
    culture of workplace profanity, and the number of other older workers who had
    been terminated or demoted. Swift applied for further review; Feeback resisted.
    We granted further review.
    II. Standard of Review.
    We exercise our discretion to limit our review to the age-discrimination
    claim. The decision of the court of appeals shall stand as the final opinion in this
    appeal affirming summary judgment dismissing Feeback’s claims for workplace
    harassment and wrongful termination in violation of public policy. See Papillon v.
    Jones, 
    892 N.W.2d 763
    , 769 (Iowa 2017).

    914 N.W.2d 330
    , 339 (Iowa 2018)).
    “Summary judgment is proper when the movant establishes there is no genuine
    issue of material fact and it is entitled to judgment as a matter of law.” 
    Id.

    914 N.W.2d at 339
    ). “We view the record in the light most
    favorable to the nonmoving party.” 
    Id.
     (quoting Deeds, 
    914 N.W.2d at 339
    ).
    III. Analysis.
    Feeback lacks direct evidence that Swift fired him because of his age.
    Rather, Feeback relies on indirect evidence in attempting to raise an inference of
    discrimination. The parties disagree whether the McDonnell Douglas analytical
    framework should be applied on summary judgment for his age discrimination
    claim under the ICRA. We first address that question and modify the framework
    for summary judgment on ICRA discrimination claims to align with the causation
    standard at trial. We then review the summary judgment record and determine
    that Feeback failed to generate a genuine issue of material fact precluding
    summary judgment on his age discrimination claim.
    A. Whether the District Court Erred by Using the McDonnell Douglas
    Framework for Summary Judgment. The district court applied the McDonnell
    Douglas burden-shifting framework in granting Swift’s motion for summary
    judgment on age discrimination. Feeback argues that framework should no
    longer be used; Swift argues that framework still controls. In Hawkins v. Grinnell
    Regional Medical Center, we abandoned use of the McDonnell Douglas analysis
    9
    at trial when instructing the jury on ICRA discrimination and retaliation claims.
    
    929 N.W.2d 261
    , 272 (Iowa 2019). We directed our state trial courts to apply the
    Price Waterhouse motivating factor causation test when instructing the jury. 
    Id.
    (citing Price Waterhouse v. Hopkins, 
    490 U.S. 228
    , 258 (1989), superseded by
    statute, Civil Rights Act of 1991, 
    Pub. L. No. 102-166, 105
     Stat. 1071 (codified
    at 42 U.S.C. § 2000e–2(m))). We also approved the “same-decision defense”
    adopted in Price Waterhouse “if properly pled and proved” by the defendant. Id.
    Accordingly, for cases that go to trial,
    when an employee proves discrimination was a motivating factor in
    the employer’s actions, the employer could avoid liability “by proving
    by a preponderance of the evidence that it would have made the
    same decision even if it had not taken the plaintiff’s gender [or other
    protected characteristics] into account.”
    Id. (alteration in original) (quoting Price Waterhouse, 
    490 U.S. at 258
    ).
    Hawkins did not address the continued use of the McDonnell Douglas
    framework at summary judgment, and we subsequently made clear that “[w]e did
    not disturb our prior law as it applies to summary judgment” in Hedlund v. State,
    
    930 N.W.2d 707
    , 719 n.8 (Iowa 2019). In Hedlund, we applied the McDonnell
    Douglas framework in affirming summary judgment dismissing an age
    discrimination claim. 
    Id.
     at 722–23. We also held Hedlund’s age discrimination
    claim failed “outside of the McDonnell Douglas framework.” 
    Id. at 723
    . We left
    open the question whether the McDonnell Douglas framework should be used on
    summary judgment going forward. See 
    id. at 719
     (“We do not need to decide this
    issue because, either way, we conclude that Hedlund has failed to raise a
    genuine issue of material fact.”).
    10
    Three justices dissented in part, concluding that we should join other
    courts in abandoning the McDonnell Douglas framework at summary judgment
    so that the same causation standard applies at summary judgment and trial.
    See 
    id.
     at 726–35 (Appel, J., concurring in part and dissenting in part, joined by
    Cady, C.J. and Wiggins, J.). Feeback relies on the Hedlund dissent to argue we
    should abandon the McDonnell Douglas framework for summary judgment. Swift
    relies on the Hedlund majority to urge that we retain it.
    We now modify the McDonnell Douglas framework for summary judgment
    on ICRA discrimination claims that rest on indirect evidence. We do so to align
    the summary judgment test with the mixed-motive causation standard and the
    same-decision defense at trial. Under our modified McDonnell Douglas test,
    employees “must carry the initial burden of establishing a prima facie case of
    age discrimination.” 
    Id. at 720
     (majority opinion). Employees do so by showing
    that they are members of a protected group (i.e., age sixty), were qualified for
    their positions, and the circumstances of their discharge raised an inference of
    discrimination. See id.; Rumsey v. Woodgrain Millwork, Inc., 
    962 N.W.2d 9
    , 22
    (Iowa 2021); see also Beasley v. Warren Unilube, Inc., 
    933 F.3d 932
    , 937 (8th Cir.
    2019). Then, the employer must “ ‘articulate some legitimate, nondiscriminatory
    reason’ for its employment action.”3 Hedlund, 
    930 N.W.2d at 720
     (quoting
    McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    , 802 (1973)); see Hawkins,
    3The   district court correctly ruled that Swift proffered a legitimate, nondiscriminatory
    reason for terminating Feeback: insubordination. See Hedlund, 
    930 N.W.2d at 720
     (holding that
    communicating “negative and disrespectful messages” about the leadership team provided a
    “legitimate, nondiscriminatory reason[]” for terminating Hedlund).
    11
    
    929 N.W.2d at 272
    . At that point, the burden shifts back to the employee to
    demonstrate the employer’s proffered reason is pretextual or, while true, was not
    the only reason for his termination and that his age was another motivating
    factor. Hawkins, 
    929 N.W.2d at 272
    .
    Iowa      Rule   of   Civil   Procedure   1.981(5)   provides   a   compatible
    burden-shifting framework on summary judgment:
    When a motion for summary judgment is made and supported as
    provided in this rule, an adverse party may not rest upon the mere
    allegations or denials in the pleadings, but the response, by
    affidavits or as otherwise provided in this rule, must set forth
    specific facts showing that there is a genuine issue for trial. If the
    adverse party does not so respond, summary judgment, if
    appropriate, shall be entered.
    And as we have long emphasized,
    The resistance must set forth specific facts which constitute
    competent evidence showing a prima facie claim. By requiring the
    resister to go beyond generalities, the basic purpose of summary
    judgment procedure is achieved: to weed out “[p]aper cases and
    defenses” in order “to make way for litigation which does have
    something to it.”
    Slaughter, 
    925 N.W.2d at 808
     (alteration in original) (quoting Thompson v. City
    of Des Moines, 
    564 N.W.2d 839
    , 841 (Iowa 1997)). To serve that salutary purpose,
    we reiterate,
    Summary judgment is not a dress rehearsal or practice run; “it is
    the put up or shut up moment in a lawsuit, when a [nonmoving]
    party must show what evidence it has that would convince a trier of
    fact to accept its version of the events.”
    
    Id.
     (alteration in original) (quoting Hammel v. Eau Galle Cheese Factory, 
    407 F.3d 852
    , 859 (7th Cir. 2005)).
    12
    Today’s case is a textbook example illustrating the burden-shifting
    function. Swift filed a motion for summary judgment supported by affidavit and
    deposition testimony showing Feeback was terminated for insubordination: a
    legitimate, nondiscriminatory reason. Under both rule 1.981(5) and the modified
    McDonnell Douglas test, to survive summary judgment, Feeback had to show he
    had admissible evidence to establish Swift’s proffered reason was a pretext for
    age discrimination and his age was a motivating factor for his termination. The
    district court ruled that Feeback fell short; the court of appeals reversed and
    found he raised genuine issues of fact precluding summary judgment. We turn
    now to the summary judgment record.
    B. Whether Any Genuine Issue of Material Fact Precluded Summary
    Judgment on Feeback’s Age Discrimination Claim. The district court
    concluded that Feeback failed to show he had sufficient evidence to convince a
    reasonable   jury   that   Swift’s   proffered   reason   for   terminating   him,
    insubordination, was a pretext for age discrimination. Feeback argued, and the
    court of appeals agreed, that he raised fact questions precluding summary
    judgment in several ways: (1) his insistence that Mulgrew was an unintended
    recipient and Swift’s “hasty” decision to fire him after Charboneau’s brief
    investigation; (2) swearing was common at the workplace; and (3) many older
    workers had been terminated, demoted, or forced out. We address each claim in
    turn, and we conclude that Feeback failed to generate a genuine issue of material
    fact precluding summary judgment on his age discrimination claim.
    13
    1. The “mistake theory,” the brevity of Swift’s investigation, and the honest
    belief rule. Feeback was fired for insubordination four days after he sent Mulgrew
    the offensive texts. Charboneau, as HR director, handled the investigation and
    concluded Feeback was insubordinate. The court of appeals determined the
    brevity of Charboneau’s investigation and Feeback’s denial that he intended the
    texts for Mulgrew raised an inference that insubordination was a pretext. The
    court of appeals stated,
    No doubt, insubordination could prompt a termination. But
    there’s a fact question about who Feeback meant to text. As soon as
    he was confronted by Charboneau, Feeback insisted Mulgrew was
    an unintended recipient. And other evidence arguably supports the
    mistake theory. One of the two messages did not make perfect sense
    in context. Granted, Mulgrew had rebuked Feeback earlier that day.
    But the central dispute did not revolve around competing versions
    of the truth. So the second text—“Believe who and what you want.”—
    did not fit with the conversation. Indeed, Mulgrew later agreed the
    second message seemed off and there could have been a “possible”
    alternative recipient.
    We disagree that this “mistake theory” or the short duration of Charboneau’s
    investigation raise a jury question on pretext.
    Charboneau did not have much to investigate. Mulgrew told him he
    received the texts after he chewed out Feeback for poor performance that day.
    Feeback admitted he sent the two texts to Mulgrew, beginning with “FUCK You!”
    that evening. Charboneau considered Feeback’s claim he intended both texts for
    a friend; he also considered the undisputed fact Feeback made no effort that
    evening to apologize or explain to Mulgrew the texts were meant for another
    person. Feeback admitted he did not actually re-send either text to the intended
    friend. He never explained why he meant to text those words to a friend on New
    14
    Year’s Eve. And Feeback admitted the last time he texted Mulgrew was over three
    months earlier, minimizing the possibility that Feeback accidentally typed those
    texts on an existing thread with Mulgrew already displayed on his phone. And
    the second text, “Believe who and what you want,” actually does make sense in
    context because Mulgrew had rebuked Feeback for telling another worker that
    Mulgrew was the worst boss Feeback ever had (an allegation Feeback did not
    deny). The second text can be read as suggesting Mulgrew believed whoever told
    him Feeback badmouthed him behind his back. Charboneau testified he
    concluded Feeback had been insubordinate. The facts reasonably support that
    conclusion.
    The question is not whether Feeback sent the texts accidentally; the
    question is whether Charboneau had a good-faith honest belief that Feeback was
    insubordinate. He did. We now adopt and apply the “honest belief rule.” See
    Pulczinski v. Trinity Structural Towers, Inc., 
    691 F.3d 996
    , 1002 (8th Cir. 2012).
    As the United States Court of Appeals for the Eighth Circuit explained:
    Our precedent establishes that the “critical inquiry in
    discrimination cases like this one is not whether the employee
    actually engaged in the conduct for which he was terminated, but
    whether the employer in good faith believed that the employee was
    guilty of the conduct justifying discharge.”
    
    Id.
     (quoting McCullough v. Univ. of Ark. for Med. Scis., 
    559 F.3d 855
    , 861–62 (8th
    Cir. 2009)). To survive summary judgment, Feeback “must show that [his]
    employer did not honestly believe the legitimate reason that it proffered in
    support of the adverse action.” 
    Id.
     Feeback made no such showing.
    15
    Nor does the brevity of Charboneau’s investigation support an inference of
    discrimination. “The appropriate scope of an internal investigation . . . is a
    business judgment, and we do not review the rationale behind such a decision.”
    
    Id. at 1005
    . “Shortcomings in an investigation alone, moreover, are not enough
    to make a submissible case.” 
    Id.
     “Employers are allowed to make even hasty
    business decisions, so long as they do not discriminate unlawfully.” 
    Id.
     There
    was nothing more for Charboneau to investigate; he interviewed the people
    involved; he had the texts, their context and timing, and Feeback’s admissions
    that he sent the texts from his phone to Mulgrew shortly after he chewed him
    out. Charboneau was not required to believe Feeback’s claim that the texts were
    intended for another. “Employment discrimination laws grant us no power ‘to sit
    as super-personnel departments reviewing the wisdom or fairness of the
    business judgments made by employers, except to the extent that those
    judgments involve intentional discrimination.’ ” Vroegh v. Iowa Dep’t of Corr.,
    
    972 N.W.2d 686
    , 695 (Iowa 2022) (quoting Hutson v. McDonnell Douglas Corp.,
    
    63 F.3d 771
    , 781 (8th Cir. 1995)). The court of appeals erred by holding that
    Feeback’s mistake theory or the brevity of Charboneau’s investigation raised a
    jury question on whether insubordination was a pretext for age discrimination.
    2. The culture of profanity at the meatpacking plant. No one should be
    surprised that Feeback had evidence swearing was commonplace at Swift’s
    Marshalltown meatpacking facility. He offered names of seventy-three other
    employees who cursed, sometimes in the presence of supervisors, who were not
    disciplined for their foul language. Mulgrew himself cursed at Feeback. The court
    16
    of appeals held that because profanity was commonplace, a jury could find
    Swift’s proffered reason for firing Feeback was a pretext for age discrimination.
    We disagree. Nobody besides Feeback texted “FUCK You!” to the plant manager
    after a negative performance review.
    We agree that a “common approach to show pretext is to introduce
    evidence that the employer treated similarly-situated employees in a disparate
    manner.” Beasley, 
    933 F.3d at 938
    . “However, ‘the test for whether someone is
    sufficiently similarly situated, as to be of use for comparison, is rigorous.’ ” 
    Id.
    (quoting Johnson v. Securitas Sec. Servs. USA, Inc., 
    769 F.3d 605
    , 613 (8th Cir.
    2014) (en banc)). Indeed, the Eighth Circuit recently reiterated that “individuals
    used for comparison must have dealt with the same supervisor, have been
    subject to the same standards, and engaged in the same conduct without any
    mitigating or distinguishing circumstances.” Gardner v. Wal-Mart Stores, Inc.,
    
    2 F.4th 745
    , 750 (8th Cir. 2021) (quoting Johnson, 
    769 F.3d at 613
    ).
    In our view, Feeback must prove that he and “the other employees were
    ‘similarly situated in all relevant respects.’ ” Ridout v. JBS USA, LLC, 
    716 F.3d 1079
    , 1085 (8th Cir. 2013) (quoting Lynn v. Deaconess Med. Ctr.-W. Campus,
    
    160 F.3d 484
    , 487 (8th Cir. 1988), abrogated by Torgerson v. City of Rochester,
    
    643 F.3d 1031
     (8th Cir. 2011) (en banc)). But Feeback need not show the other
    employees committed “the exact same offense.” 
    Id.
     (quoting Lynn, 160 F.3d at
    488). Rather, he must establish that he “was treated differently than other
    employees whose violations were of comparable seriousness.” Id. (quoting Lynn,
    160 F.3d at 488). Feeback failed to make that showing. There is a big difference
    17
    between swearing around a boss and texting “FUCK You!” to the boss after he
    chewed you out. Feeback identified no other Swift employee who committed an
    offense of comparable seriousness without being terminated. The court of
    appeals erred in concluding that a culture of profanity at Swift supports an
    inference that its proffered reason (insubordination) for terminating Feeback was
    a pretext for age discrimination.
    The United States Court of Appeals for the Sixth Circuit addressed a
    similar culture-of-profanity claim in Hausler v. General Electric Co., 
    134 F. App’x 890
     (6th Cir. 2005). Hausler yelled, “Fuck you. That’s bullshit,” directly at his
    supervisor and was terminated from employment three days later. 
    Id. at 891
    . He
    sued for age discrimination and argued that because profanity was common at
    the   workplace,     the   employer’s   proffered   reason   for   terminating   him
    (insubordination) was a pretext for age discrimination. The district court granted
    summary judgment dismissing Hausler’s age discrimination claim. 
    Id. at 892
    .
    The facts, procedural posture, and arguments of the parties are strikingly similar
    to Feeback’s case:
    Feeback                                    Hausler
    60 years old; employed 30 years at        49 years old; employed 20 years at

    The Sixth Circuit squarely rejected Hausler’s contention that profanity was
    so common in the workplace that there was a fact question on pretext; that is,
    whether he was terminated for his age, not for insubordination. 
    Id. at 893
    . The
    Sixth Circuit concluded there is a difference between swearing generally and
    swearing at the supervisor. 
    Id.
     The same is true for Feeback.
    3. Other older management employees who were forced out since 1994. The
    court of appeals agreed with Feeback that he raised an inference of
    discrimination by identifying other older employees who suffered adverse
    employment actions. Like the district court, we conclude this evidence was
    insufficient to avoid summary judgment.
    Feeback’s affidavit named nine people over age fifty-five who were fired or
    demoted after 1994. But Feeback admitted in his deposition that he lacked
    personal knowledge as to whether specific employees were terminated because
    of their age. Under the “contradictory affidavit rule,” the district court
    appropriately disregarded his affidavit testimony about other employees. See
    Susie v. Fam. Health Care of Siouxland, P.L.C., 
    942 N.W.2d 333
    , 339 (Iowa 2020)
    (“The essence of this rule is that there is no genuine issue of fact because the
    deposition testimony precludes consideration of contradictory affidavits.”).
    19
    Feeback does not claim he was personally involved in management’s
    decision to fire or demote these individuals. Apart from their ages, he offered no
    direct evidence that age was the motivating factor for their terminations or
    demotions. Feeback’s unsupported speculation that these individuals were
    forced out because of their age is insufficient to raise a jury question. See
    Godfrey v. State, 
    962 N.W.2d 84
    , 106 (Iowa 2021) (“Godfrey’s personal,
    conclusory beliefs are insufficient as a matter of law to generate a fact question
    for the jury.”); see also Hausler, 134 F. App’x at 894 (agreeing with the district
    court that evidence supervisor “disproportionately disciplined [three] older
    workers . . . was insufficient to create an issue of fact as to pretext because the
    statistical sample was too small and because the majority of employees under
    [his] supervision were over forty years old”); McIntosh v. Country Club of Little
    Rock, No. 4:17–cv–757–DPM, 
    2019 WL 2618145
    , at *1 (E.D. Ark. June 26, 2019)
    (granting motion for summary judgment and stating that although plaintiff
    pointed out the Country Club fired four other older employees, “there’s no
    evidence that these employees were fired because of their age”); Prochaska v.
    Color-Box, L.L.C., No. C04–1009–LRR, 
    2005 WL 1410846
    , at *12 (N.D. Iowa
    June 1, 2005) (granting summary judgment on age discrimination claim and
    rejecting argument that plaintiff’s list of other older employees who were
    terminated created fact question on pretext when he admitted he lacked
    firsthand knowledge about the reasons for their adverse employment decisions).
    Feeback offered no expert testimony or statistical evidence that this
    management-level turnover over that span of decades was unusual for a
    20
    meatpacking plant of Swift’s size. It is undisputed that Swift employed more than
    100 employees age sixty or older when Feeback was terminated. Feeback’s
    affidavit testimony about what happened to other older employees failed to raise
    a jury question on age discrimination.
    IV. Disposition.
    For the foregoing reasons, we vacate the decision of the court of appeals
    on Feeback’s age discrimination claim and affirm its decision on the remaining
    claims. We affirm the district court’s summary judgment on all claims.
    DECISION OF COURT OF APPEALS AFFIRMED IN PART AND
    VACATED IN PART; DISTRICT COURT SUMMARY JUDGMENT AFFIRMED.
    All justices concur except May, J., who takes no part.
