    THOMPSON, Circuit Judge.
    PREFACE
    Sometime on or around March 22, 2014 — all dates here
    are in that year, by the way — Shayne Parker committed two legal
    no-nos:   he possessed 50 rounds of 38-caliber ammo while being a
    convicted felon, and he transported a SCCY Model CXP 9-mm pistol
    into his state of residence without a license.      Or so a federal
    grand jury in Massachusetts alleged in an indictment charging him
    with violating 18 U.S.C. §§ 922(g)(1) and (a)(3).    Parker pleaded
    not guilty.   But a trial jury found him guilty as charged.   And a
    district judge sentenced him to 60 months in prison and 3 years of
    supervised release.
    Parker now appeals only his conviction, arguing that the
    judge triply erred — first, by not individually voir diring
    prospective jurors about their feelings toward race; then, by
    admitting evidence of other gun and ammo purchases (what we will
    call "other-acts evidence"); and, finally, by instructing the jury
    on willful blindness.1    Concluding that none of his challenges
    rises to the level of reversible error, we affirm.
    1 As relevant to our dispute, voir diring is a process through
    which "a judge or lawyer" examines "a prospective juror" to see if
    "the prospect is qualified and suitable to serve on a jury." See
    Voir Dire, Black's Law Dictionary (10th ed. 2014).

    HOW THE CASE GOT HERE2
    On   March    21,   Parker   drove   with   Ronald    Scott   from
    Massachusetts (their state of residence) to New Hampshire and
    checked into the Keene Inn in Keene, New Hampshire.            The room was
    registered in Parker's name.       There they hooked up with Mitchell
    Riddell, a drug customer of Scott's.       And Riddell talked to Scott
    — in Parker's presence — about buying guns.
    The trio got together again the next day, March 22, this
    time joined by Melanie LaMott.     Turns out LaMott could legally buy
    firearms in the Granite State and had agreed with Riddell to act
    as a straw buyer.3     Parker and Scott are African-American; Riddell
    and LaMott are white — why this matters will become clear in the
    next section of this opinion.
    The foursome first went to the Alstead Gun Shop in
    Alstead, New Hampshire.       They checked out some handguns but left
    because Scott became uncomfortable with someone in the shop.
    2 Because Parker does not attack the sufficiency of the
    evidence against him, we describe the pertinent facts as neutrally
    as possible. See, e.g., United States v. Cox, 
    851 F.3d 113
    , 118
    n.1 (1st Cir. 2017); United States v. Rodríguez–Soler, 
    773 F.3d 289
    , 290 (1st Cir. 2014).
    3 See Straw Purchase, Black's Law Dictionary (10th ed. 2014)
    (defining "straw purchase" as "[s]omeone's buying of a firearm for
    another who is prohibited to make such a purchase because of a
    prior conviction, an order of protection, or some similar
    judicially imposed proscription").
    - 3 -
    The gang then headed to the Sporting and Hunting Depot
    in Charlestown, New Hampshire, with Parker driving Scott in a
    Subaru and Riddell driving LaMott in a Toyota.         After they all
    entered the store, LaMott bought a bunch of firearms, one of which
    was a SCCY Model CXP 9-mm pistol.        Satisfied with the purchases,
    the group went to LaMott's Keene apartment, where Scott gave
    Riddell and LaMott crack cocaine as a partial payment for their
    services.      Parker and Scott handled the firearms and said how
    pleased they were with them.
    The quartet set out for Boston, Massachusetts — Riddell
    and LaMott in Riddell's car, and Parker and Scott in the Subaru —
    but stopped en route at Dick's Sporting Goods Store in Keene so
    Scott and LaMott could buy ammunition, including the 38-caliber
    ammunition.      Once in Boston, Parker and Scott examined the guns
    and ammo.     And Scott gave Riddell and LaMott the rest of the drugs
    they were owed for helping out.
    At some point, the police caught wind of what was going
    on.       And Parker's arrest, indictment, and conviction followed
    apace.      As we said, his brief on appeal advances three claims of
    error — though all are without merit, for reasons we explain in
    the pages that follow.4
    4We will note additional details as needed in discussing
    Parker's issues.
    - 4 -
    INDIVIDUAL VOIR DIRE
    Background
    After Parker elected to go to trial, the parties geared
    up to select an impartial jury.   As part of that process, Parker's
    counsel asked the judge if he planned on conducting any individual
    voir dire.    "Only at sidebar, if someone raises [a] hand" in
    response to a group question, the judge said — though, he stressed,
    "we're not going to do individualized voir dire in the sense of
    . . . doing it in the lobby or doing it segregated."   But Parker's
    lawyer believed the judge's proposed approach would not do enough
    to uncover potential jurors holding racist views. And so he pushed
    for individual voir dire, arguing to the judge as follows:
       As a statistical matter, the criminal-justice system treats
    African-Americans much harsher than others.
       The race of the cooperating straw buyers added a "cross-
    racial component" to the case.
       The charged ammo/firearm "offenses" also "play[ed] into a
    stereotype."
       One could not "realistically expect jurors to respond in
    the audience in front of all of the[] other prospective
    - 5 -
    jurors    to    questions    about   whether   they   are    biased   or
    prejudiced against people based on their race."
        And individual voir dire would better help him assess a
    potential juror's demeanor and thus better help him decide
    whether    he    or   she   had   answered   the   judge's   questions
    truthfully.
    Relying on these reasons — offered without any evidence
    (like, say, a social-science study) to back them up — counsel asked
    the judge to ask these five questions (the bracketed numbers are
    ours):
    [1] Do you have any feelings or opinions about black
    people that would cause you to question your ability to
    be impartial in evaluating the evidence in this case?
    [2] Would the fact that Mr. Parker is a black man make
    it more difficult for you to decide a verdict in his
    favor than if he were white?
    [3] Do you believe that black men are more likely to
    commit a crime than others?
    [4] Have you had any experiences with black people that
    might make you unable to be fair and impartial in this
    case?
    [5] Can you honestly assure the court that the race of
    the defendant will not affect your ability to be fair
    and impartial?
    Responding to counsel's request, the judge said that it
    is "by no means clear" that "people will be inhibited from simply
    raising their hands in a crowd full of strangers without uttering
    a word for fear of being shamed into admitting racial prejudice,"
    - 6 -
    but "will freely admit racial prejudice to a judicial officer in
    a black robe with lawyers and court reporters and law clerks
    present."    So he denied the call for individual voir dire.          "This
    is a relatively routine case," the judge then stressed — "not a
    death penalty case, not a murder case, not a highly publicized
    case."    Because "[t]here's no racial angle to it" — "like a victim
    and   a   perpetrator   being   of    different   races"   —   and   because
    "[n]othing about it particularly w[ould] evoke a strong emotional
    response or a racially charged response," the judge saw no reason
    "to take the highly unusual and time-consuming and resource-
    consuming step of individual voir dire."          Asked by the defense to
    reconsider, the judge adhered to his ruling — despite counsel's
    insistence that Donald Trump's recent victory in the Massachusetts
    Republican primary had "engendered serious racial polarization"
    and that individual voir dire would add only "a couple of extra
    hours" to the process.
    The judge proceeded to empanel the jury.           And per his
    usual practice, the judge told the prospective jurors that "[i]t
    is very important that you give truthful responses."           And then the
    judge said:
    Ladies and gentlemen, when I ask a question if you think
    your answer is yes or your answer is yes, please raise
    your hand. If you raise your hand, I'm going to call
    you over here to the sidebar one-by-one. I'll find out
    what the issue is. I might explore it with you a little
    bit.
    - 7 -
    The   judge   started   voir    dire   off   with   some   basic
    icebreaking questions.     For instance, after mentioning the names
    of the potential witnesses, the judge asked, "Do any of you know
    or are you related to . . . or acquainted" with "any of those
    people?"   A few potential jurors raised their hands, just like the
    judge had asked them to do.        And after calling them to sidebar,
    the judge asked some probing follow-up questions.
    Before turning to the issue of racial bias, the judge
    noted that "it can be difficult sometimes for people to talk openly
    about [race] or to be honest or open about whatever feelings they
    may have on [that] subject[], but your duties and obligations as
    citizens and as potential jurors require you to be completely
    honest with me."    Having said that, the judge asked the group if
    anyone had "any feelings of any kind that may affect your ability
    in any way to be fair and impartial in the trial of an African-
    American defendant because of his race."          No one raised a hand.
    At sidebar, Parker's lawyer restated his position that
    group questions answered with a show of hands did not suffice
    because "there's no way anybody is going to come forward on that."
    "All right," the judge said, "[o]ther than individualized voir
    dire, is there any particular question you want me to ask that I
    have not asked to the group?"         Defense counsel identified two,
    which the judge posed to the group:        "[D]o any of you believe that
    - 8 -
    it is more likely that the defendant is guilty of the crime because
    he is African-American?"        And "[h]ave any of you had an experience
    of any kind with African-Americans that would affect your ability
    to be a fair and impartial juror in the trial of this case?"              No
    one raised a hand in response to either question.                 The judge
    empaneled a jury of twelve, plus two alternates.              And as seated,
    the jury had at least one African-American member (Parker's lawyer
    told us at oral argument that he "believe[d] there was one or two
    African-Americans" on the jury).
    Arguments
    As Parker sees it, the judge not only had to voir dire
    potential jurors about possible racial prejudice, but he also had
    an       obligation   to   question    them    individually    rather   than
    collectively — and to speak with each one outside the presence of
    the others.      For support, Parker's brief talks about
       the "cross racial" makeup of the persons involved in the
    charged offenses — i.e., an African-American defendant and
    white straw buyers;
       the   "nature"    of   the   crime,   which   "created     inherent
    stereotyping with [an] African American . . . from Boston
    . . . preying on [white] drug addicted" New Hampshirites;
       "the statistical evidence of bias against African Americans
    in the criminal justice process";
    - 9 -
       how the trial took place in a racially-charged atmosphere
    caused "by the then ongoing presidential election campaign";
    and
       how one cannot expect a potential juror to cop to being a
    racist in front of other potential jurors.
    The government counters that "the circumstances" of
    Parker's "case" did not require the judge to question prospective
    jurors about racial bias.         So, the government adds, the judge
    actually went above and beyond what was required because he did
    quiz them on prejudice.       And, the government insists, Parker has
    not shown that the judge's decision to question collectively rather
    than individually infracted any constitutional command.
    Standard of Review
    Our review of the judge's voir dire decision looks only
    for abuses of discretion.       See, e.g., United States v. Gelin, 
    712 F.3d 612
    , 621 (1st Cir. 2013).          The key "question under this
    standard . . . is not whether we, if sitting as a court of first
    instance,    would    have    weighed   the   relevant   considerations
    differently," but instead "whether our review of the record leaves
    us with a definite and firm conviction that the court below
    committed a clear error of judgment in the conclusion it reached
    upon a weighing of the relevant factors."         
    Id. (quotations and
    citations omitted).

    Analysis
    A defendant has a constitutional right to trial by an
    impartial jury, see U.S. Const. amend. VI — something voir dire
    helps safeguard by giving "the court and counsel" a chance "to
    examine" potential jurors "for impartiality," see Peña-Rodriguez
    v. Colorado, 
    137 S. Ct. 855
    , 866 (2017).               And when it comes to
    describing the judiciary's role here, the Supreme Court has pulled
    no punches:       "to ensure that individuals who sit on juries are
    free of racial bias," our "Constitution at times demands that
    defendants be permitted to ask questions about racial bias during
    voir dire."      
    Peña-Rodriguez, 137 S. Ct. at 868
    (emphasis removed).
    That is so because "discrimination on the basis of race, 'odious
    in all aspects, is especially pernicious in the administration of
    justice.'"       
    Id. (quoting Rose
    v. Mitchell, 
    443 U.S. 545
    , 555
    (1979)).
    Ever-faithful to controlling precedent, we have said
    that "[t]he possibility of racial prejudice" creates "special
    concerns"    —   concerns   that    in   "certain     limited    circumstances"
    require the asking of "special voir dire question[s]."                     United
    States v. Brown, 
    938 F.2d 1482
    , 1485 (1st Cir. 1991); see also
    
    Gelin, 712 F.3d at 621
    .            By way of example, Brown pulled two
    "special    circumstances"    cases      from   the    U.S.     Reports.      One
    "involv[ed] a black civil rights activist whose defense to a
    - 11 -
    marijuana possession charge was that he had been framed by local
    white 
    police." 938 F.2d at 1485
    (citing Ham v. South Carolina,
    
    409 U.S. 524
    (1973)).    And the other "involv[ed] a sentencing of
    a black defendant who had been convicted of [the] capital offense"
    of killing a white storekeeper.   See 
    id. (citing Turner
    v. Murray,
    
    476 U.S. 28
    (1986)).     Both are cases where "[r]ace was . . .
    'inextricably bound up with the conduct of [defendant's] trial.'"
    See 
    id. (quoting Ristaino
    v. Ross, 
    424 U.S. 589
    , 597 (1976)).   But
    we have also said that voir dire "[o]rdinarily . . . need not
    include questions regarding racial prejudice" and that "[t]he mere
    fact that a defendant is black does not alone" activate "the
    special questioning requirement" — though we (echoing the Supreme
    Court) have stressed too that the better approach "'generally is
    to propound appropriate questions designed to identify racial
    prejudice if requested by the defendant,'" even in situations where
    it is not constitutionally required.    See 
    id. (quoting Ristaino
    ,
    424 U.S. at 597 n.9).5
    5 To the extent Parker claims that Peña-Rodriquez overruled
    these just-cited cases, his claim is off base. Peña-Rodriguez is
    not a jury-selection case, but is instead a case involving "the
    no-impeachment rule" — i.e., a "general rule" saying that once the
    jurors' "verdict has entered, it will not later be called into
    question based on the comments or conclusions they expressed during
    
    deliberations." 137 S. Ct. at 861
    . Peña-Rodriguez's holding is
    "that where a juror makes a clear statement that indicates he or
    she relied on racial stereotypes or animus to convict a criminal
    defendant, the [Constitution] requires that the no-impeachment
    - 12 -
    Having said all this, however, we need not referee the
    parties' duel over whether the judge had to ask voir dire questions
    to smoke out possible racial bias.   And this is because even if we
    assume (without deciding) that he had to explore the issue during
    the jury-selection process, the judge did exactly that — asking
    (as we detailed above) the group of potential jurors not one but
    three questions designed to weed out racial bias (including two
    questions suggested by defense counsel).       Fairly viewed, the
    judge's questions during group voir dire captured the essence of
    what Parker wanted asked during the hoped-for individual voir dire,
    even if they did not match up word for word — certainly they showed
    the judge's sensitivity to racial-prejudice concerns.      Perhaps
    that is why Parker spends most of his time arguing that the judge
    should have done an individual voir dire, talking to each potential
    rule give way in order to permit the trial court to consider the
    evidence of the juror's statement and any resulting denial of the
    jury trial guarantee." 
    Id. at 869.
    Sure, as Parker notes, Peña-
    Rodriguez made powerful points aplenty, like: while "[a]ll forms
    of improper bias pose challenges to the trial process[,] . . .
    there is a sound basis to treat racial bias with added precaution."
    
    Id. But none
    of the cases in the above paragraph says anything to
    the contrary — actually, they are on the same page as Peña-
    Rodriguez when it comes to discussing the poisonous effects of
    racial prejudice on the justice system. So we may — no, must —
    follow them.
    - 13 -
    juror outside of the others' earshot.      Though forcefully presented
    by able counsel, his argument does not persuade.
    Trial judges enjoy much discretion about how to conduct
    voir dire, including whether to conduct individual voir dire. See,
    e.g., United States v. Pérez-González, 
    445 F.3d 39
    , 46-47 (1st
    Cir. 2006).    And certainly there are situations where individual
    voir dire makes sense.     See generally Horton v. Allen, 
    370 F.3d 75
    , 80-83 (1st Cir. 2004) (holding that defense counsel had not
    acted ineffectively by joining the prosecutor in requesting that
    the trial judge ask prospective jurors during a closed individual
    voir dire "about the effect that racial prejudice and pretrial
    publicity   could   have   on   their   ability   to   decide   the   case
    impartially").   But no authority exists to support Parker's theory
    — floated during oral argument — that if the case facts suggest
    the judge should voir dire on race, then only an individual voir
    dire will do.    On the contrary, in cases where "the subject of
    possible racial bias must be 'covered' by the questioning of the
    trial court in the course of its examination of potential jurors,"
    the Supreme Court has been "careful not to specify the particulars
    by which this could be done" — noting, for example, that it has
    "not . . . require[d] questioning of individual jurors about facts
    or experiences that might have led to racial bias."        See Mu'Min v.
    Virginia, 
    500 U.S. 415
    , 431 (1991).       And as the government tells
    - 14 -
    us — without contradiction from Parker — the only circuit to
    squarely consider the issue before us held that, "ordinarily,
    questioning jurors as a group" is constitutionally sufficient,
    "even when the defendant belongs to a racial, ethnic, or religious
    minority and juror bias on one or more of these grounds might be
    a concern."   See United States v. Hosseini, 
    679 F.3d 544
    , 555 (7th
    Cir. 2012).
    Trying to convince us that his case is anything but
    ordinary, Parker turns to a concurrence in a nearly 30-year-old
    Eleventh Circuit opinion, Berryhill v. Zant, 
    858 F.2d 633
    (11th
    Cir. 1988) — a habeas case involving a crime that caused a torrent
    of pretrial publicity.        Unfortunately for Parker, the Berryhill
    concurrence is not a difference-maker here.
    To over-simplify (slightly) for present purposes, the
    district judge there concluded that a state court's decision to
    deny Berryhill's request "for a sequestered" individual voir dire
    violated his fair-trial rights.         
    Id. at 640-43.
          In taking this
    issue on (the majority did not speak to that subject because it
    affirmed   the   grant   of   habeas   relief   on   other   grounds),   the
    concurrence quoted the district judge, who said — and this is the
    money quote as far as Parker is concerned — that the "inhibiting
    effect of a large audience . . . made a careful and probing voir
    dire all the more important."          
    Id. at 641
    (Clark, J., specially
    - 15 -
    concurring) (emphasis added).         Agreeing with the district judge
    that the state court's voir dire had not done enough to uncover
    the possible influence of pretrial publicity, the concurrence
    suggested that at any new trial, the state court should do a
    general group voir dire on the pretrial-publicity issue (asking
    them whether they had read or heard anything about the case, for
    example) and then do "an individualized segregated voir dire" if
    necessary.     
    Id. at 642-43
    (Clark, J., specially concurring).          A
    "sequestered individual voir dire," the concurrence stressed,
    would prevent "those prospective jurors who had not read or heard
    about the case" from being "contaminat[ed]" by "the responses of
    those who had."    
    Id. at 642
    (Clark, J., specially concurring).
    As we understand his brief, Parker is claiming that the
    "inhibiting effect" concept gives some oomph to his core contention
    that people will not answer race questions honestly during a group
    voir dire. Like the concurring judge in Berryhill, we do not doubt
    that   the   "inhibiting    effect"    concern   makes   a   diligent   and
    thoughtful voir dire a must.          But again, that is precisely what
    our judge did here.        And his voir dire procedure — questioning
    jury prospects about race as a group (prospects who had already
    shown a willingness to raise their hands, mind you) and allowing
    for individualized follow-up questions at sidebar if necessary —
    jibed with the procedure recommended by the Berryhill concurrence.
    - 16 -
    Which is why this out-of-circuit opinion is not the game-changer
    that Parker thinks it is.
    Summarizing   succinctly,     given   the   particulars    of
    Parker's case, we believe that the tack taken by the experienced
    judge passes the abuse-of-discretion test with room to spare.       See
    generally 
    Pérez-González, 445 F.3d at 46
    (noting that "[w]hile we

    voir-dire issue.
    OTHER-ACTS EVIDENCE
    Background
    Before the trial kicked off, the government moved in
    limine seeking permission to introduce evidence of gun and ammo
    purchases beyond the ones that formed the bases of the indictment's
    counts.   Zeroing in on other straw buys that went down on March
    22, as well as buys that occurred on March 10 and 16 (more on these
    in a bit), the government argued, first, that this other-acts
    evidence showed Parker's "knowledge and intent to transport and
    receive the firearms in the state of Massachusetts," and, second,
    that the other-acts evidence's probative worth outweighed any
    unfairly prejudicial effect.   Parker opposed the motion.
    - 17 -
    Having   gotten   the   green    light   from   the   judge,   the
    government introduced evidence at trial that on March 10, Parker
    and Scott got the straw purchasers to buy multiple firearms at the
    Alstead Gun Shop:       Parker drove Scott in the Subaru to New
    Hampshire, where they met with Riddell and a woman named Sandra
    Egbert.   Scott gave Riddell money and general instructions on what
    guns to buy.    The four — Parker, Scott, Riddell, and Egbert —
    entered the store.    Egbert bought three guns.        At some point, the
    guns ended up in the Subaru.       And Parker said that he really liked
    one of them — "a silver and black SCCY 9 millimeter handgun" — and
    that he wanted to buy "more like it."
    The government also introduced evidence of the straw
    purchases that happened less than a week later, on March 16:
    Before the buy, Parker and Scott headed to New Hampshire and stayed
    at the Keene Inn in a room registered to Parker.             They met with
    Riddell and LaMott.     Parker again said that he wanted more "SCCY"
    guns.   And using Scott's money, LaMott then bought three firearms
    (one of which was an "SCCY" handgun) at the Sporting and Hunting
    Depot in Charlestown.    After stopping at LaMott's Keene apartment,
    the group drove to Boston (Riddell drove LaMott in his car).
    Parker handled the guns back at the Boston apartment.            And Riddell
    and LaMott returned to New Hampshire after getting crack cocaine
    as payment for their services.
    - 18 -
    And, finally, the government introduced evidence of the
    March 22 gun buy — one that occurred contemporaneously with the
    purchase of the SCCY Model CXP 9-mm pistol that was the subject of
    the indictment:      At the Sporting and Hunting Depot, Parker told
    Riddell that he and Scott wanted an assault rifle hanging on the
    wall.     And Parker and Scott then gave Riddell money to buy the
    weapon.     LaMott made the purchase (again, at the same time she
    bought the SCCY Model CXP 9-mm pistol). And later that day, LaMott
    and Scott bought ammo at Dick's Sporting Goods Store in Keene.
    Importantly, at various points in the trial the judge
    instructed the jury regarding the purposes for which the other-
    acts evidence was introduced.      Here is a perfect example of the
    kind of instructions he gave (the judge gave this one the first
    time he admitted the evidence):
    I'm permitting you to hear evidence of . . . transactions
    [beyond those underlying the indictment] for the purpose
    of permitting you to evaluate that evidence for whatever
    weight you choose to give it in considering [Parker's]
    intent, motive, knowledge, whether he had a particular
    plan, but, again, this is not charged conduct.
    . . . [Y]ou must take special care to ensure that
    you do not consider this evidence as evidence that
    [Parker] has a bad character or somehow is a bad person,
    and, therefore, committed the crime.
    You must evaluate the charged crime[s] according to
    their own evidence and not because of whatever character
    [Parker] does or does not have.
    - 19 -
    Hard on the heels of this instruction, the judge — at defense
    counsel's request — told the jury that "another way of framing
    . . . the same concept is you may not conclude that [Parker] had
    a propensity to commit a crime and, therefore, committed the crime,
    that he acted in accordance with bad character, so to speak."        And
    to give another example, in his final jury charge the judge gave
    this reminder:
    You've heard evidence that [Parker] may have
    committed acts similar to those charged in this case on
    one or more different occasions. You may consider that
    evidence only for the limited purposes of deciding:
    Whether [he] had the necessary intent, knowledge,
    or state of mind to commit the crimes charged in the
    indictment;
    Whether [he] had a motive or opportunity to commit
    the crimes charged; or
    Whether [he] acted according to a plan to commit
    the crimes charged.
    You may not use that evidence for any other purpose.
    In particular, you may not use it to infer that, because
    of his character, or because he has a propensity to act
    in a certain way, [he] committed the crimes charged.
    Arguments
    Parker thinks the judge reversibly erred here because
    (by   his   lights)   the   "uncharged   crimes"   evidence   constituted
    "prejudicial" other-acts evidence that the government used to fill
    lots of trial time merely to portray him as bad man, thus "creating
    [a] significant risk" that the jury convicted him "based on his
    - 20 -
    propensity    to   commit   a   crime."6    The   government   thinks   the
    opposite, saying the judge rightly ruled that the evidence had
    non-propensity purposes, chiefly to establish Parker's knowledge
    and intent.     And, the government writes, the evidence "was also
    not unfairly prejudicial" to Parker — particularly given the
    judge's "deftly and timely deployed limiting instructions," which
    "eliminated any potential for unfair prejudice."        Wrapping up, the
    government says that if error occurred it was harmless given the
    considerable "uncontested evidence of Parker's guilt."
    Standard of Review
    Our review of the judge's decision to admit other-acts
    evidence is for abuse of discretion only.7            See, e.g., United
    States v. Munyenyezi, 
    781 F.3d 532
    , 539 (1st Cir. 2015); United
    States v. George, 
    761 F.3d 42
    , 58 (1st Cir. 2014).        And convincing
    us that the judge abused his discretion takes no small effort.
    See United States v. Hadfield, 
    918 F.2d 987
    , 995 (1st Cir. 1990).
    We say that because "[o]nly rarely — and in extraordinarily
    6 Parker calls the evidence "irrelevant" in part of a sentence
    buried in the summary-of-the-argument section to his brief, but
    then does nothing to elaborate on it. So we hold any potential
    relevance-based argument waived for lack of development.       See,
    e.g., United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990).
    7 The parties agree (at least implicitly) that Parker's
    counsel did enough below so that this issue gets abuse-of-
    discretion (and not simply plain-error) review. And we have no
    basis to conclude otherwise.

    compelling circumstances — will we, from the vista of a cold
    appellate record, reverse a district court's on-the-spot judgment
    concerning the relative weighing of probative value and unfair
    effect." 
    Id. (quoting Freeman
    v. Package Mach. Co., 
    865 F.2d 1331
    ,
    1340 (1st Cir. 1988)).
    Analysis
    No one doubts that prosecutors can offer evidence of
    uncharged crimes so long as the evidence goes to proving something
    other than the defendant's bad character, like proving his intent
    or knowledge.       See 
    Munyenyezi, 781 F.3d at 539
    (citing Fed. R.
    Evid. 404(b)(2)); see also 
    Rodríguez-Soler, 773 F.3d at 297
    (noting
    that   the   list    of   permissible   purposes    "is   illustrative,   not
    exhaustive").       But even then, the judge can keep the evidence out
    if its potential for unfair prejudice "substantially outweigh[s]"
    its probative worth. See Fed. R. Evid. 403; see also United States
    v. Zeuli, 
    725 F.2d 813
    , 816 (1st Cir. 1984) (explaining that if
    other-acts    evidence     is   probative    of    some   issue   other   than
    character, "it is admissible, subject only to the rarely invoked
    limitations of Rule 403").        With these preliminaries out of the
    way, we can dispose of Parker's claim quickly enough.
    The government is exactly right that prosecutors used
    the other-acts evidence not to show Parker's bad character but to
    show his intent and knowledge.          Take the other-acts evidence of
    - 22 -
    the March 22 purchases.          Parker's expressing an interest in the
    assault-style rifle, giving money to help buy it, and handling it
    back in Boston (on the very day of the charged criminal purchases)
    showed his awareness of — and his participation in — the group's
    gun/ammo-purchasing project.          Ditto for the other-acts evidence of
    the March 10 and 16 purchases, since those other acts not only
    occurred just before the charged acts, they also closely allied
    with the types of crimes Parker was on trial for — similarities
    include stays at the Keene Inn, in a room registered to Parker;
    the shuttling of guns and ammo from New Hampshire to Massachusetts;
    and the giving of drugs to straw buyers as payment for their
    services.    All of this showed that Parker was a knowledgeable
    scheme member and not simply an "unknowing" innocent.                  See United
    States v. Aguilar-Aranceta, 
    58 F.3d 796
    , 798-99 (1st Cir. 1995)
    (stressing   that   if    the    evidence      might   admit    of    an    innocent
    "explanation" and the parties dispute the defendant's "intent and
    knowledge," the judge has the "discretion to permit the government
    to introduce evidence of prior similar offenses to demonstrate the
    unlikeliness   that      the    defendant    was   merely      an    innocent     and
    unknowing    bystander");       see   also     
    Hadfield, 918 F.2d at 994
    (collecting cases upholding the admission of a defendant's prior
    - 23 -
    involvement in similar illegal activities "to prove knowledge and
    intent").8
    And prejudicial though it was — nearly all evidence is
    prejudicial, "by helping one side and hurting the other" — the
    complained-of other-acts evidence (admitted for the perfectly
    permissible purpose of showing Parker's knowledge and intent) was
    not unfairly prejudicial.     See 
    Rodríguez-Soler, 773 F.3d at 296
    (discussing how Rule 403 works).    Parker tries to establish unfair
    prejudice by suggesting that the other-acts evidence ate up too
    much court time.     But the record shows that in this 5-day trial
    involving 15 witnesses, testimony about the gun-and-ammo purchases
    came from just 2 testifiers, Riddell and LaMott. Also, the judge's
    limiting instructions on the proper use of the other-acts evidence
    — crafted with defense counsel's input, mind you — did enough to
    reduce any possible prejudice.     See, e.g., United States v. Moon,
    8 Parker talks up a non-binding (and un-appealed) district
    court opinion, United States v. Da Lin, 
    707 F. Supp. 2d 158
    (D.
    N.H. 2010), hoping against hope that we might see the other-acts-
    evidence issue his way. Among other things, the district judge in
    Da Lin found "insufficient evidence to determine whether the prior
    conduct" at issue there "was 'sufficiently similar' to that alleged
    in the pending charges to 'allow a juror to draw a reasonable
    inference probative of knowledge and intent.'" 
    Id. at 162
    (quoting
    United States v. Landrau–Lopez, 
    444 F.3d 19
    , 24 (1st Cir. 2006)).
    Compare Da Lin to our case and the difference is night and day,
    given our conclusion that the similarity between the uncharged and
    charged conduct here had probative value in establishing Parker's
    knowledge and intent. So Da Lin helps Parker not at all.

    The long and the short of it is that the judge did not
    abuse his discretion by admitting the other-acts evidence.9
    Two issues down, one to go.
    WILLFUL-BLINDNESS INSTRUCTION
    Background
    At a charge conference held before the close of evidence,
    the judge asked the parties if he should give a willful-blindness
    instruction and if so, why.
    The prosecutor responded that yes, the judge should give
    the charge.   For support, the prosecutor pointed to Parker's post-
    arrest statement to law enforcement that Scott had paid him $200
    "like three times" to drive him to New Hampshire but that "each
    time, when we stayed in the hotel, when we came back to Boston,
    the only thing we came back with was marijuana."        Parker added
    that he "didn't want to know" what else Scott was up to — and
    though Scott once went to the car to get "stuff," a word Parker
    took to mean guns, Parker claimed that he left the room because he
    "didn't want to know about nothing."     According to the prosecutor,
    Parker's comments show "that he's willfully blind by attempting to
    9 Given this conclusion, there is no need for a harmless-
    error analysis.
    - 25 -
    close his eyes to the conduct."             "I think it's fairly presented in
    the evidence or it certainly will be when the government introduces
    [the] statement tomorrow," the prosecutor stressed.
    Parker's    lawyer    saw     things      differently,     to   put    it
    mildly.      The government does not "have to" put Parker's statement
    in evidence, counsel said.         "We're not putting any evidence in" on
    the    lack-of-knowledge       issue,     he    added.      And,   he    noted,     the
    prosecutor "can't put [the statement] in and then say I want to
    get     a    particular        instruction       that     otherwise       would      be
    inappropriate."      Focusing on the proposed instruction's language,
    counsel complained that the judge could not use it because it would
    have "the effect of shifting the burden of proof" on the questions
    of Parker's knowledge and intent.
    The judge reserved ruling on the matter, saying he wanted
    to see what Parker said, "assuming [the statement] comes in." "I'm
    going to go back and look at the case law on willful blindness,
    when it's appropriate and when it isn't and give some more thought
    to it," the judge added.         The next day, the judge told the parties
    that    he    intended    to    give    a      willful-blindness        instruction.
    Regardless of whether Parker claims a lack of knowledge, the judge
    ruled, his statement — if it is as represented by the government
    — "suggest[s] a conscious course of deliberate ignorance," and the
    charge "as drafted does not suggest in any way that an inference
    - 26 -
    of knowledge is mandated."         Later that morning, the government —
    without objection — introduced the statement.
    The government rested its case that same day.               The
    defense, in turn, rested too — without calling any witnesses.             The
    attorneys then made their closing arguments.            And the judge gave
    the final charge to the jury.
    Pertinently for our purposes, the judge instructed the
    jury that it "may infer" Parker "had knowledge of a fact if" it
    found Parker "deliberately closed his eyes to a fact that otherwise
    would have been obvious to him."          "[T]o make such an inference,"
    the judge explained, the jury had to "find two things:             [f]irst,
    that [Parker] was aware of a high probability of the fact in
    question; and, [s]econd, that [he] consciously and deliberately
    avoided learning that fact — that is to say, he willfully made
    himself blind to that fact."         And, the judge emphasized, whether
    Parker "deliberately closed his eyes to [a] fact, and, if so, what
    inference, if any, should be drawn," was "entirely up to you."
    Also,   the    judge   cautioned    the   jury   that   Parker   "must   have
    consciously and deliberately avoided learning the fact" — neither
    "[m]ere negligence, recklessness or mistake in failing to learn
    the fact," nor "[t]he fact that a reasonable person in [Parker's]
    position would have known the fact," sufficed.             Plus, the judge
    warned that a finding that Parker "made himself willfully blind to
    - 27 -
    one or more facts" was not alone "sufficient to find him guilty of
    a crime."     Rather, the prosecution had to "prove[] all of the
    elements of the crimes as charged in the indictment" — something
    the judge stressed after referring to Parker's presumption of
    innocence and the prosecution's burden to prove beyond a reasonable
    doubt the elements of each offense.
    Parker's attorney renewed his objection to the willful-
    blindness instruction after the judge gave the charge.
    Arguments
    Parker writes that the judge should not have given a
    willful-blindness   instruction   because   (a)   he    "introduced   no
    affirmative evidence" of his "lack of knowledge"; (b) the evidence
    "did not suggest a conscious course of deliberate ignorance" on
    his part; and (c) the charge relieved the government of its burden
    to prove his "knowledge" of the illegal scheme.        For its part, the
    government argues that Parker waived the claim by not properly
    developing it in his appellate papers.      If not waived, says the
    government, his argument is dead wrong on each front.        And on top
    of that, the government claims that even if the evidence did not
    justify a willful-blindness instruction, any error was harmless
    because "the evidence was sufficient for the jury to find that
    Parker had actual knowledge of the firearms purchase scheme."
    - 28 -
    Standard of Review
    Some older cases — as the government suggests — imply
    that uncertainty surrounds what standard of review applies in
    assessing     a    judge's   decision       to   give   a   willful-blindness
    instruction.       See United States v. Appolon, 
    695 F.3d 44
    , 63 (1st
    Cir. 2012).       But recent cases have brought clarity to this area,
    explaining, for example, that the standard of review depends on
    the nature and circumstances of the particular claim of error.
    See United States v. De La Cruz, 
    835 F.3d 1
    , 12 (1st Cir. 2016).
    Here, as we said a second ago, Parker's claims turn on whether the
    trial evidence supported a willful-blindness instruction and on
    whether the issued instruction relieved the government of its
    burden to prove his knowledge.              And given our current caselaw,
    these claims demand de novo review.               See id.; see also United
    States v. George, 
    841 F.3d 55
    , 65 (1st Cir. 2016).
    Analysis
    Because we can uphold the judge's willful-blindness
    charge on the merits, we need not decide whether Parker waived the
    issue because of inadequate briefing.            To the merits then.
    Lots    of   "criminal    statutes      require   proof    that     a
    defendant   acted     knowingly,"     our    judicial   superiors     tell    us.
    Global-Tech Appliances, Inc. v. SEB S.A., 
    563 U.S. 754
    , 766 (2011).
    But willful blindness is tantamount to knowledge.                   See United
    - 29 -
    States v. Rivera-Rodríguez, 
    318 F.3d 268
    , 272 (1st Cir. 2003).
    And when applied, the so-called willful-blindness doctrine lets
    prosecutors prove a defendant's knowledge by showing that he
    "deliberately shield[ed] [himself] from clear evidence of critical
    facts that are strongly suggested by the circumstances."   Global-
    Tech Appliances, 
    Inc., 563 U.S. at 766
    .   An oft-repeated rationale
    for the doctrine is that one who acts like that is "just as
    culpable" as one who has "actual knowledge" — in other words,
    "persons who know enough to blind themselves to direct proof of
    critical facts in effect have actual knowledge of those facts."
    
    Id. A willful-blindness
    instruction is appropriate only when
    (a) the defendant alleges he lacked knowledge, (b) the evidence —
    examined in the light most flattering to the prosecution — shows
    he deliberately closed his eyes to the true facts, and (c) the
    instruction, viewed in context, does not suggest that an inference
    of knowledge is required rather than permitted.   See, e.g., United
    States v. Azubike, 
    564 F.3d 59
    , 66 (1st Cir. 2009); United States
    v. Singh, 
    222 F.3d 6
    , 11 (1st Cir. 2000).   We address each part of
    this test in turn.
    As for part (a), Parker's big argument is that he offered
    "no affirmative evidence" of his "lack of knowledge." True, Parker
    never testified at trial and so did not put his lack of guilty
    - 30 -
    knowledge directly in issue.                  But "that circumstance is not
    dispositive."          
    Singh, 222 F.3d at 11
    .        Our cases have made crystal
    clear        that    part   (a)   "of   the   test    for       a    willful    blindness
    instruction does not depend on a showing of an explicit denial of
    guilty knowledge out of the defendant's own mouth" — what matters
    is whether "a practical evaluation of the record reveals that the
    defense was pitched in that direction."                   
    Id. And that
    is the case
    here.
    To begin, Parker's post-arrest statement — admitted into
    evidence without objection — suggests an attempt on his part to
    convince the authorities that he had no idea what the people around
    him were doing.         And Parker offers no developed argument as to why
    the judge could not rely on this evidence in his willful-blindness
    ruling.        More, the trial transcript shows that Parker staked his
    defense on convincing the jury that he did not personally buy or
    transport the firearms, and was not there when others bought or
    talked about them — a defensive theme reflected by his counsel's
    questions       on    cross-examination       and    by    his      counsel's    comments
    during closing arguments.10             And as the government's brief notes,
    10
    To take only one of the examples, defense counsel said
    during closing that Parker "didn't buy any firearm, he didn't
    transport it, it was never at his home."       And even though a
    fingerprint matching Parker's was found on an ammunition package,
    counsel claimed that "[t]here's no credible evidence" that Parker
    ever "touched" the ammo — or for that matter, the gun. Riddell
    - 31 -
    Parker's team implemented this strategy in the hopes of persuading
    jurors that he had zero knowledge of what Scott, Riddell, and
    LaMott were up to — a point Parker does not contest in his reply
    brief.
    Parker fares no better under the part (b) of the test.
    The government offered direct evidence that he consciously averted
    his eyes to the group's illegal escapades.           We are again talking
    about Parker's post-arrest statement in which he claimed that he
    "didn't want to know about nothing" and that he left the room when
    Scott went to the car to bring the guns into the Boston apartment
    (Scott had said that he was going to get "stuff," but Parker knew
    "stuff" meant "guns").     That is enough to satisfy this part of the
    test.    See United States v. Brandon, 
    17 F.3d 409
    , 452 (1st Cir.
    1994) (finding no error in giving a willful-blindness instruction
    where the defendant said he "didn't want to know anything about"
    a   "scheme    to   fraudulently   represent   the    existence   of   down
    payments").
    Finally, regarding the test's part (c), Parker makes no
    effort to explain why he thinks the judge's willful-blindness
    instruction mandated an inference of knowledge.            Maybe that is
    because the judge took care to avoid giving the impression that
    made "stuff up" — saying Parker did "this" or "that" — to curry
    favor with the authorities, counsel stressed.

    such an inference was mandatory rather than permissive.             Recall,
    for example, how the judge told the jurors that it was "entirely
    up to you to determine whether [Parker] deliberately closed his
    eyes to [a] fact, and, if so, what inference, if any, should be
    drawn."   Add to this the other parts of the judge's final charge
    (highlighted      above)   and   we    think   Parker's   claim   that   the
    instruction improperly implied that a guilty-knowledge inference
    was obligatory is a no-go.             See 
    Singh, 222 F.3d at 11
    & n.4
    (approving    a   nearly   identical     willful-blindness   instruction);
    United States v. Gabriele, 
    63 F.3d 61
    , 66-67 & n.6 (1st Cir. 1995)
    (same); 
    Brandon, 17 F.3d at 451-52
    & n.72 (same).
    The bottom line is that we see no reversible error with
    this aspect of the case.11
    FINAL WORDS
    Our work over, we affirm Parker's conviction.
    11 Given our holding, we need not take on the government's
    other theories for why we should affirm the judge's instruction.
