    REVIEW of a decision of the Court of Appeals.                        Affirmed in
    part, reversed in part.
    ¶1       REBECCA      FRANK   DALLET,   J.   This        is    a   review     of    a
    published decision of the court of appeals1 reversing the judgment
    of conviction entered against David Gutierrez.
    ¶2       Gutierrez was convicted of multiple counts of sexual
    assault and enticement of his stepdaughter.                    In a postconviction

    motion, Gutierrez alleged the denial of his constitutional right
    to an impartial jury and to effective assistance of counsel.
    Gutierrez appealed the denial of his postconviction motion.                      He
    also appealed his judgment of conviction on the grounds that the
    circuit court2 erred in its decision to exclude unidentified DNA
    evidence and to admit "other acts" evidence.               The court of appeals
    reversed the circuit court's decision to exclude the unidentified
    DNA   evidence   and   affirmed        its   decision     to   admit   other    acts
    evidence.   The judgment of conviction was vacated and the case was
    remanded for a new trial.         The State petitioned for review.
    ¶3    We   conclude   that       the   court   of    appeals     erroneously
    reversed the circuit court's exercise of discretion in excluding
    unidentified DNA evidence.            We further conclude that the court of
    appeals properly affirmed the circuit court's admission of other
    acts evidence.     Lastly, we conclude that Gutierrez was not denied
    his right to an impartial jury or his right to effective assistance
    of counsel. Accordingly, we reverse the court of appeals' decision
    as to the unidentified DNA evidence and affirm its decision as to
    the other acts evidence. We also affirm the circuit court's denial
    of Gutierrez's postconviction motion.
    I.    BACKGROUND
    ¶4    On   November   2,    2012,      twelve-year-old      A.R.   told    her
    cousin she was afraid to return home because her stepfather,
    Gutierrez, touched her the night before.                In a forensic interview
    conducted later that day, A.R. alleged that the prior evening,
    2The Honorable W. Andrew Voigt of the Green Lake County
    Circuit Court presided.
    2
    No.   2017AP2364-CR
    November 1, Gutierrez removed her clothes, touched her genitals,
    made her touch his genitals, performed oral sex on her, forced her
    to perform oral sex on him, ejaculated in her mouth, and attempted
    to penetrate her with his penis.        A.R. further alleged that
    Gutierrez first sexually assaulted her when she was six years old
    by luring her into a closet and performing oral sex on her.      A.R.
    also provided specific details about an alleged sexual assault
    that took place in a van some time between May and October 2011
    and in a garage some time between September 2011 and May 2012.
    ¶5     After her forensic interview, A.R. submitted to a sexual
    assault forensic exam where she indicated that in the 24 hours
    since the assault she had urinated, defecated, washed her genital
    area, taken a shower, drank liquid, brushed her teeth, swished out
    her mouth, and changed her clothes. The nurse collected a perioral
    swab from A.R. to test for DNA.3
    ¶6     Additional DNA swabs were taken from two pairs of A.R.'s
    underwear seized during the execution of a search warrant on
    November 3.    One pair, which A.R. indicated she wore during the
    November 1 assault, was pulled mid-cycle from the washing machine.
    It did not match the description A.R. had initially given to the
    police.    The second pair, which was purportedly the underwear A.R.
    wore on November 2, was retrieved from a pile of soiled laundry.
    DNA from at least three unidentified males was detected on the
    perioral swab, and DNA from at least five unidentified males was
    3   "Perioral" refers to the exterior area around a person's
    mouth.     See Perioral, Attorney's Dictionary of Medicine (Oct.
    2019).

    No.     2017AP2364-CR
    detected on the underwear swabs.                    The testing excluded Gutierrez
    as    a       contributor      to   either    DNA    mixture.        The      testing   also
    determined that none of the DNA was from semen or saliva.
    ¶7     Based on the three allegations of sexual assault that
    took place between 2011 and 2012, Gutierrez was charged with three
    counts of sexual assault of a child under the age of thirteen,
    three counts of incest with a child by stepparent, three counts of
    child enticement, and one count of exposing a child to harmful
    material.4         Prior to trial, Gutierrez moved to admit the DNA test
    results.         The State objected, arguing that the DNA evidence was
    not   relevant       and       that   any    probative      value    was      substantially
    outweighed by the danger of undue prejudice, confusion of the
    issues, and misleading the jury. See Wis. Stat. §§ 904.01, 904.03.
    Additionally,            the    State       asserted       that   the      indication     of
    unidentified male DNA on the swabs would invite speculation as to
    why male DNA would be around A.R.'s mouth and on her underwear, a
    purpose         barred    by    Wisconsin's         rape    shield   law,       Wis.    Stat.
    § 972.11(2)(b).           Defense counsel argued that the unidentified DNA
    evidence was highly probative to rebut the State's theory that
    Gutierrez's DNA would not likely be found on A.R. since she had
    washed and wiped herself in the time between the assault and when
    the swabs were collected, and that this purpose was not contrary
    to the rape shield law.
    See Wis. Stat. §§ 948.02(1)(e), 948.06(1m), 948.07(1),
    4
    & 948.11(2)(a) (2017-18).   All subsequent references to the
    Wisconsin Statutes are to the 2017-18 version unless otherwise
    indicated.

    No.    2017AP2364-CR
    ¶8         The circuit court ruled that Gutierrez could introduce
    evidence only that DNA testing was performed on the perioral and
    underwear swabs and that his DNA was not found on those swabs.
    While       the    circuit      court    "agree[d]    with    [defense      counsel's]
    analysis of the rape shield law," it precluded Gutierrez from
    presenting the unidentified DNA evidence because the lack of
    information surrounding the sources of the DNA and when it had
    been       deposited     rendered       its   probative    value    "extraordinarily
    limited."          The circuit court also raised concerns that expert
    testimony on this issue could consume half a day and could take
    the trial "down a rabbit hole."                   As an alternative, the court
    allowed       defense      counsel       to   generally      explore      how   DNA   is
    transferred, how long foreign DNA remains viable on another person,
    and how easily DNA can be washed or wiped off with the expert
    witness.
    ¶9         The   State   moved    to   admit   as   "other      acts"    evidence
    allegations of prior sexual assaults dating back to when A.R. was
    approximately six years old.                  In light of the greater latitude
    rule applicable in child sexual assault cases,5 the circuit court
    granted the State's motion in part, admitting only the first
    incident of alleged assault for the limited purposes of proving
    The circuit court initially denied the State's motion to
    5
    admit the other acts evidence but reversed that decision upon the
    State's motion to reconsider.    Specifically, the circuit court
    cited the greater latitude rule which permits a greater latitude
    of proof as to other acts "in sexual assault cases, particularly
    cases that involve sexual assault of a child . . . ." State v.

    motive and providing context and background.                The court agreed to
    instruct the jury that if it believed A.R., it could consider
    Gutierrez's other act of child sexual assault for only these
    limited purposes.6
    ¶10       With Gutierrez's trial only weeks away, defense counsel
    disclosed a recent claim by Gutierrez's mother that while staying
    with       her   in    Texas,   A.R.    confessed    that   she    fabricated    the
    allegations           because   she    was   upset   with   Gutierrez.        While
    Gutierrez's mother appeared on his amended witness list, defense
    counsel announced at the outset of Gutierrez's case-in-chief that
    The circuit court modeled its cautionary instruction after
    6
    Wis JI——Criminal 275 (2015). Specifically, the court instructed
    the jury:
    Evidence has been presented regarding other conduct
    of the defendant for which the defendant is not on trial.
    Specifically, evidence has been presented that the
    defendant had sexual contact with [A.R.] in a closet
    when she was about six years old and living in the State
    of Texas and that the defendant told [A.R.] not to tell
    anyone because it was a secret. If you find that this
    conduct did occur, you should consider it only on the
    issues of motive, context or background.
    You may not consider this evidence to conclude that
    the defendant has a certain character or a certain
    character trait and that the defendant acted in
    conformity with that trait or character with respect to
    the offense charged in this case.
    . . .
    You may consider this evidence only for the
    purposes I have described, giving it the weight you
    determine it deserves. It is not to be used to conclude
    that the defendant is a bad person and for that reason
    is guilty of the offense charged.
    6
    No.   2017AP2364-CR
    he would not be calling her to testify.             Defense counsel opted
    instead to confront A.R. with the claim on cross-examination.
    ¶11   During jury selection, defense counsel asked whether any
    prospective juror felt they could not be fair and impartial given
    the nature of the charges.      Juror R.G. responded, "I don't know if
    I could be impartial.      I work with kids.       I drive school bus, so
    I deal with kids all the time, and I just, I don't know if I can
    be impartial."     Defense counsel moved the court to excuse Juror
    R.G. for cause, but the State objected arguing that there needed
    to be a "little more certainty."          The circuit court never ruled on
    the motion.      Defense counsel did not renew the motion, question
    Juror R.G. further, or exercise a peremptory strike on her.                She
    subsequently served on Gutierrez's jury.
    ¶12   One of the witnesses called by the defense at trial was
    State    Crime   Laboratory   DNA     Analyst    Samantha    Delfosse,     who
    testified that Gutierrez's DNA was not present on A.R.'s perioral
    or underwear swabs.      On cross-examination, the State elicited her
    testimony that DNA can be washed, scrubbed, or wiped off, and the
    more a person is washing or wiping, "the more likely you are
    removing any kind of DNA that was deposited."          Defense counsel did
    not conduct any redirect examination.
    ¶13   The    jury   ultimately   found     Gutierrez   guilty   on   nine
    counts.7
    7 The jury found Gutierrez not guilty of exposing a child to
    harmful material. See Wis. Stat. § 948.11(2)(a).

    ¶14    Gutierrez filed a postconviction motion, arguing that he
    was denied his right to an impartial jury.           He also asserted that
    his defense counsel was unconstitutionally ineffective because he
    did not further question or exercise a peremptory strike on Juror
    R.G., or call his mother as a witness.8           At the Machner9 hearing,
    defense counsel testified that he did not remember Juror R.G., her
    statement, or why he exercised each of Gutierrez's peremptory
    strikes on other prospective jurors.            He admitted that "the best
    I can say is I must have felt there were other people that I needed
    off the jury more than her."          As for not calling Gutierrez's mother
    as a witness, defense counsel stated that he did not make that
    decision    until    the   defense's     case-in-chief.       In   making   that
    decision, he considered that Gutierrez's mother could not recall
    specifics surrounding the recantation such as why A.R. was at her
    home in Texas, when the recantation was made, or why she did not
    immediately report it.          Defense counsel described Gutierrez's
    mother as a "loose cannon" who "loved to talk" and determined that
    these characteristics would allow her credibility to be undermined
    on cross-examination.          Finally, he expressed concern that by
    calling the defendant's mother as a witness, the jury might infer
    that the defense was desperate.
    ¶15    The     circuit   court    denied   Gutierrez's    postconviction
    motion and affirmed the judgment of conviction. Gutierrez appealed
    8 Gutierrez also claimed his counsel was unconstitutionally
    ineffective for not properly subpoenaing his wife to testify at
    trial, but this claim was not pursued on appeal.

    also    challenged   the    circuit   court's   decision    to    exclude    the
    unidentified DNA evidence and to allow the other acts evidence.
    ¶16   The   court    of   appeals   reversed   the   circuit   court's
    judgment of conviction and remanded the case for a new trial.                The
    court of appeals held that the circuit court erroneously exercised
    its discretion in excluding the unidentified DNA evidence and that
    the error was not harmless.10         State v. Gutierrez, 
    2019 WI App 41
    ,
    ¶¶9-12, 
    388 Wis. 2d 312
    , 
    933 N.W.2d 133
    .              It reasoned that the
    exclusion of this evidence "incorrectly led [the jury] to believe
    that the underwear and mouth swabs contained no DNA evidence,"
    thereby bolstering the State's theory that A.R. washed or wiped
    Gutierrez's DNA off and preventing Gutierrez from rebutting that
    theory.11
    Id., ¶9. For
    purposes of remand, the court of appeals
    also decided that the circuit court did not erroneously admit the
    other acts evidence in light of the greater latitude rule.
    Id., The dissent
    concluded that the majority misapplied the
    10
    standard of review because the circuit court properly exercised
    its discretion to exclude the unidentified DNA evidence.
    Gutierrez, 
    388 Wis. 2d 312
    , ¶¶16-38.
    The court of appeals, in a footnote, formulated a
    11
    constitutional argument for Gutierrez based on the Confrontation
    Clause and Compulsory Process Clause found in the United States
    Constitution and Wisconsin Constitution.          Gutierrez, 
    388 Wis. 2d 312
    , ¶8 n.4 (citing U.S. Const. amend. VI; Wis. Const.
    art. I, § 7).    As the court of appeals notes, however, this
    argument is gleaned from a single reference in Gutierrez's reply
    brief to the fundamental right of a criminal defendant to present
    a defense. This amounts to a forfeiture of the issue and we do
    not address it further.   See A.O. Smith Corp. v. Allstate Ins.
    Companies,

    , 492, 
    588 N.W.2d 285

    The State petitioned for review, which we granted.
    II.   STANDARD OF REVIEW
    ¶17   A decision to admit or exclude evidence is within the
    circuit court's discretion.     State v. Warbelton, 
    2009 WI 6
    , ¶17,
    
    315 Wis. 2d 253
    , 
    759 N.W.2d 557
    .         This court will reverse that
    decision only if the circuit court erroneously exercised its
    discretion.
    Id. ¶18 When
    reviewing a claim of juror bias, we "uphold the
    circuit court's factual finding that a prospective juror is or is
    not subjectively biased unless it is clearly erroneous."           State v.
    Lepsch, 
    2017 WI 27
    , ¶23, 
    374 Wis. 2d 98
    , 
    892 N.W.2d 682
    .
    ¶19   Finally,   whether   a    defendant   received       ineffective
    assistance of counsel is a mixed question of fact and law.             State
    v. Wayerski, 
    2019 WI 11
    , ¶32, 
    385 Wis. 2d 344
    , 
    922 N.W.2d 468
    .
    The circuit court's factual findings, including the circumstances
    of the case and trial counsel's conduct and strategy, will be
    upheld unless they are clearly erroneous.
    Id. Whether counsel's
    performance satisfies the constitutional standard for ineffective
    assistance of counsel is a question of law we review de novo.
    Id. III. ANALYSIS
    ¶20   We first address whether the circuit court properly
    exercised its discretion in excluding unidentified DNA evidence
    and admitting other acts evidence of a prior child sexual assault.
    Next we consider Gutierrez's postconviction claims that he was
    10
    No.   2017AP2364-CR
    denied the right to an impartial jury and effective assistance of
    counsel.
    A.   Unidentified DNA Evidence
    ¶21   The State argues that the court of appeals erred in
    second-guessing the circuit court's discretionary decision to
    exclude the unidentified DNA evidence found on A.R.'s perioral and
    underwear swabs.    An appellate court upholds a circuit court's
    exercise of discretion to admit or exclude evidence where it
    "examined the relevant facts, applied a proper legal standard,
    and, using a demonstrated rational process, reached a reasonable
    conclusion."   State v. Chamblis, 
    2015 WI 53
    , ¶20, 
    362 Wis. 2d 370
    ,
    
    864 N.W.2d 806
    .
    ¶22   Here, the proper legal standard is the balancing test
    set forth in Wis. Stat. § 904.03:     "Although relevant, evidence
    may be excluded if its probative value is substantially outweighed
    by the danger of unfair prejudice, confusion of the issues, or
    misleading the jury, or by considerations of undue delay, waste of
    time, or needless presentation of cumulative evidence."      Applying
    this proper legal standard to all of the relevant facts using a
    demonstrated rational process, it was reasonable for the circuit
    court to conclude that the probative value of the unidentified DNA
    was "extraordinarily limited."
    ¶23   First and foremost, Gutierrez was not the source of the
    DNA and no known male was identified as a contributor.        The DNA
    was not semen or saliva as might be expected where the allegations
    include oral sex, attempted vaginal penetration, and ejaculation.
    As recognized by the circuit court, the DNA could have come from
    11
    No.    2017AP2364-CR
    a skin cell, hair follicle, or some other source deposited during
    an innocuous interaction.
    ¶24   Moreover, there was no evidence of when the DNA had been
    deposited.     The perioral and underwear samples were not collected
    until   roughly    24    and   48    hours   after   the    alleged        assault,
    respectively.     Neither party could say whether the DNA found on
    those samples was deposited before the time of the alleged assault,
    or during the extended interim period afterwards.                      As the State
    emphasized,     the     time   gap   also    presented     the     potential     for
    contamination of the underwear, as one pair was pulled still wet
    from a running washing machine and the other was taken from a pile
    of soiled laundry.        The circuit court could reasonably conclude
    that    without   knowing      the   critical    timeframe        for     when   the
    unidentified DNA evidence was deposited, the evidence had limited
    probative value in rebutting the State's theory that A.R. washed
    or wiped off Gutierrez's DNA.
    ¶25   Finally, A.R.'s initial description of the underwear
    worn during the alleged assault was inconsistent with the underwear
    tested.      The questions regarding the timeframe, source of and
    contributors to the DNA, and the high potential for contamination
    of the underwear all gave the circuit court reasonable grounds to
    conclude that the DNA had low probative value.
    ¶26   The circuit court could also reasonably conclude that
    the limited probative value of the unidentified DNA evidence was
    substantially outweighed by the dangers of confusion of the issues,
    misleading the jury, and waste of time pursuant to Wis. Stat.
    § 904.03.    Specifically, the circuit court raised concern that the
    12
    No.     2017AP2364-CR
    questions surrounding the unidentified male DNA would lead the
    trial down "a rabbit hole" calling for speculative testimony.                  A
    jury could be confused or misled by the collateral issue of why
    male DNA was present and therefore distracted from the pertinent
    issue of whether Gutierrez's DNA had been present but was washed
    or wiped off.     The circuit court also expressed apprehension that
    the expert testimony on this collateral issue would consume a
    significant portion of the trial.            The circuit court provided for
    an alternative way to elicit the relevant information:                  defense
    counsel could question the expert witness generally on how DNA is
    transferred, how long foreign DNA remains viable on another person,
    and how easily DNA can be washed or wiped off.
    ¶27      The court of appeals disagreed with the low probative
    value the circuit court assigned to the unidentified DNA evidence.
    The court of appeals also dismissed the factors considered by the
    circuit court pursuant to Wis. Stat. § 904.03:                  the dangers of
    confusion of the issues, misleading the jury, and wasting time.
    Gutierrez, 
    388 Wis. 2d 312
    , ¶¶6, 9-10.           While the court of appeals
    may have preferred that the circuit court give more weight to the
    evidence's probative value, it "may not substitute its discretion
    for that of the circuit court."         State v. Rhodes, 
    2011 WI 73
    , ¶26,
    
    336 Wis. 2d 64
    , 
    799 N.W.2d 850
    .          Instead, appellate courts should
    "look   for    reasons   to   sustain    a    trial   court's     discretionary
    decision."     State v. Wiskerchen, 
    2019 WI 1
    , ¶18, 
    385 Wis. 2d 120
    ,
    
    921 N.W.2d 730
    (quoted source omitted).           Our review of the record
    shows the circuit court applied the proper legal standard to the
    relevant facts and reached a reasonable discretionary decision.
    13
    No.     2017AP2364-CR
    The court of appeals thus erred in reversing the circuit court's
    decision to exclude the unidentified DNA evidence.
    B.    Other Acts Evidence of Child Sexual Assault
    ¶28   Gutierrez argues that the         circuit court erroneously
    exercised its discretion in admitting evidence that he sexually
    assaulted A.R. when she was approximately six years old.            We agree
    with the court of appeals that the circuit court properly admitted
    this other acts evidence of child sexual assault in light of the
    greater latitude rule.
    ¶29   Evidence of other crimes, wrongs, or acts may be admitted
    if:    (1) offered for an acceptable purpose under Wis. Stat.
    § 904.04(2); (2) relevant under Wis. Stat. § 904.01; and (3) its
    probative value is not substantially outweighed by the danger of
    unfair prejudice, confusion, or delay under Wis. Stat. § 904.03.
    See State v. Sullivan, 
    216 Wis. 2d 768
    , 772-73, 
    576 N.W.2d 30
    (1998). Alongside this general framework, courts accept a "greater
    latitude of proof as to other like occurrences" of sexual assault,
    particularly against children.           State v. Davidson, 
    2000 WI 91
    ,
    ¶36, 
    236 Wis. 2d 537
    , 
    613 N.W.2d 606
    ; see also § 904.04(2)(b)1.
    (codifying the common law greater latitude rule).                The greater
    latitude rule liberalizes each of Sullivan's three prongs in favor
    of admitting similar acts of child sexual assault.             See Davidson,
    
    236 Wis. 2d 537
    , ¶51.          The greater latitude rule, however, does
    not relieve a court of the duty to ensure that the other acts
    evidence is offered for a proper purpose, is relevant, and its
    probative        value   is   not   substantially   outweighed    by   undue
    prejudice.
    Id., ¶52. 14

    1.   Acceptable purposes
    ¶30   Under   Wis.    Stat.    § 904.04(2)(a),     evidence    of   other
    "crimes, wrongs, or acts" is inadmissible unless offered for an
    acceptable   purpose      such     as    "motive,    opportunity,    intent,
    preparation, plan, knowledge, identity, or absence of mistake or
    accident." Here, the circuit court instructed the jury to consider
    the other acts evidence only for the purposes of motive, context,
    and background.
    ¶31   The other acts evidence of sexual assault was offered
    for the admissible purpose of proving that Gutierrez's motive was
    to intentionally touch A.R. for the purpose of sexual arousal or
    gratification.     See     Wis.    Stat.     § 948.01(5)(a)   (defining    the
    element of "sexual contact").           "When a defendant's motive for an
    alleged sexual assault is an element of the charged crime, we have
    held that other crimes evidence may be offered for the purpose of
    establishing . . . motive."        State v. Hurley, 
    2015 WI 35
    , ¶72, 
    361 Wis. 2d 529
    , 
    861 N.W.2d 174
    (alteration in original) (emphasis
    omitted) (quoting State v. Hunt, 
    2003 WI 81
    , ¶60, 
    263 Wis. 2d 1
    ,
    
    666 N.W.2d 771
    ); see also Davidson, 
    236 Wis. 2d 537
    , ¶¶57-59.              The
    evidence further provided context for A.R.'s delayed disclosure
    and a more complete story for the jury.             Context and background,
    while not expressly listed in Wis. Stat. § 904.04(2)(a), can also
    be acceptable purposes.        See State v. Marinez, 
    2011 WI 12
    , ¶27,
    
    331 Wis. 2d 568
    , 
    797 N.W.2d 399
    ("We have previously recognized
    that context, . . . and providing a more complete background are
    permissible purposes under Wis. Stat. § 904.04(2)(a).") (citing
    Hunt, 
    263 Wis. 2d 1
    , ¶58).         The circuit court did not erroneously
    15
    No.     2017AP2364-CR
    exercise   its   discretion    by     concluding     motive,           context,     and
    background were acceptable purposes for the admission of other
    acts evidence.
    2.    Relevance
    ¶32   Other   acts   evidence      is    relevant      under       Wis.   Stat.
    § 904.01 if it:     (1) "relates to a fact or proposition that is of
    consequence to the determination of the action"; and (2) is
    probative because it "has a tendency to make a consequential fact
    more probable or less probable than it would be without the
    evidence." 
    Sullivan, 216 Wis. 2d at 785
    –86. We consider relevancy
    in the context of the greater latitude rule.                 See Davidson, 
    236 Wis. 2d 537
    , ¶51.
    ¶33   Several of the counts——sexual assault of a child under
    the age of thirteen, incest with a child by stepparent, and child
    enticement——required the State to prove "sexual contact," defined
    under Wis. Stat. § 948.01(5)(a) as intentional touching for the
    purpose of sexual arousal or gratification.                      See     Wis. Stat.
    §§ 948.02(1)(e),    948.06(1m),       948.07(1).          This    motive,      as   an
    element of the charges, is a fact of consequence.                 See Hurley, 
    361 Wis. 2d 529
    , ¶83 (citing Davidson, 
    236 Wis. 2d 537
    , ¶65).                           The
    other acts evidence was also relevant to A.R.'s credibility, a
    consequential    fact   in   this     case.
    Id., ¶81 ("A
        witness's
    credibility is always 'consequential' within the meaning of Wis.
    Stat. § 904.01.") (quoting Marinez, 
    331 Wis. 2d 568
    , ¶34).
    ¶34   The   probative    value    of    the   other     acts       evidence     is
    measured by the factual similarities it shares with the charged
    conduct.   See Davidson, 
    236 Wis. 2d 537
    , ¶67; see also Sullivan,
    16
    No.    
    2017AP2364-CR 216 Wis. 2d at 787
    .     Here, the charged conduct and the other acts
    evidence share many factual similarities:                  the same victim and
    assailant; similar alleged acts of sexual contact; and the secluded
    location of all of the assaults.             These strong similarities are
    highly probative as to Gutierrez's motive in the charged assaults
    and as to A.R.'s credibility.
    3.    Unfair prejudice
    ¶35    Lastly, Wis. Stat. § 904.03 requires the circuit court
    to determine whether the probative value of the other acts evidence
    "is substantially outweighed by the danger of unfair prejudice,
    confusion    of   the   issues    or        misleading     the     jury,     or   by
    considerations    of    undue    delay,      waste    of    time       or   needless
    presentation of cumulative evidence."                Unfair prejudice occurs
    when the evidence "influence[s] the outcome by improper means or
    if it appeals to the jury's sympathies, arouses its sense of
    horror, provokes its instinct to punish or otherwise causes a jury
    to base its decision on something other than the established
    propositions in the case." Davidson, 
    236 Wis. 2d 537
    , ¶73 (quoting
    State v. Gray, 
    225 Wis. 2d 39
    , 64, 
    590 N.W.2d 918
    (1999)).
    ¶36    The other acts evidence was highly probative as to
    motive, context, and background because of the marked similarities
    with the charged conduct.         See
    id., ¶¶75-76; supra
    , 
    ¶34.                   The
    danger of unfair prejudice based on the jury hearing evidence of
    other, similar conduct did not substantially outweigh its high
    probative value, especially in light of the greater latitude rule.
    See, e.g, State v. Veach, 
    2002 WI 110
    , ¶91, 
    255 Wis. 2d 390
    , 
    648 N.W.2d 447
    (holding that even "graphic, disturbing, and extremely
    17
    No.   2017AP2364-CR
    prejudicial" testimony detailing a similar other act of child
    sexual assault is admissible under the greater latitude rule).
    Additionally, the cautionary instruction mitigated the possibility
    of unfair prejudice.     See Hurley, 
    361 Wis. 2d 529
    , ¶89 ("Limiting
    instructions     substantially   mitigate     any   unfair   prejudicial
    effect.").
    ¶37    Because the other acts evidence of child sexual assault
    was probative as to motive, context, and background and was not
    substantially outweighed by unfair prejudice, we affirm the court
    of appeals in upholding the circuit court's admission of that
    evidence.
    C.   Juror Bias
    ¶38    Gutierrez argues that by not further questioning or
    excusing an equivocating juror, the circuit court denied him his
    constitutional right to an impartial jury. See U.S. Const. amends.
    VI, XIV; Wis. Const. art. 1, § 7.      "To be impartial, a juror must
    be indifferent and capable of basing his or her verdict upon the
    evidence developed at trial."    Lepsch, 
    374 Wis. 2d 98
    , ¶21 (citing
    State v. Faucher, 
    227 Wis. 2d 700
    , 715, 
    596 N.W.2d 770
    (1999)).
    ¶39    There are three disqualifying forms of juror bias:        (1)
    statutory; (2) subjective; and (3) objective. 
    Faucher, 227 Wis. 2d at 716
    .     Gutierrez's claim falls under subjective bias because it
    turns on "the words and the demeanor of the prospective juror."
    Id. at 717.
        "A prospective juror is subjectively biased if the
    record reflects that the juror is not a reasonable person who is
    sincerely willing to set aside any opinion or prior knowledge that
    the prospective juror might have."     State v. Williams, 
    2015 WI 75
    ,
    18
    No.    2017AP2364-CR
    ¶79, 
    364 Wis. 2d 126
    , 
    867 N.W.2d 736
    .             "Prospective jurors are
    presumed impartial," and it is Gutierrez's burden to rebut this
    presumption.    Lepsch, 
    374 Wis. 2d 98
    , ¶22 (quoting State v. Funk,
    
    2011 WI 62
    , ¶31, 
    335 Wis. 2d 369
    , 
    799 N.W.2d 421
    ).
    ¶40   Gutierrez argues that Juror R.G.'s statement "I don't
    know if I could be impartial" is enough to establish subjective
    bias and cites as support State v. Carter, 
    2002 WI App 55
    , 
    250 Wis. 2d 851
    , 
    641 N.W.2d 517
    .          In Carter, the court of appeals
    concluded that a juror was subjectively biased based upon his
    affirmative response when asked if his brother-in-law's experience
    as a sexual assault victim would influence his ability to be fair
    and impartial in a sexual assault trial.
    Id., ¶¶3, 12-13.
    ¶41   Contrary     to   Gutierrez's    contention,         Juror   R.G.'s
    uncertainty is distinguishable from the juror's definitive "yes"
    in Carter.     We accept and tolerate that a prospective juror may
    honestly equivocate in response to voir dire questions exploring
    their fears, biases, and predilections.            See State v. Erickson,
    
    227 Wis. 2d 758
    , 776, 
    596 N.W.2d 749
    (1999) ("[W]e expect a circuit
    court to use voir dire to explore a prospective juror's fears,
    biases, and predilections and fully expect a juror's honest answers
    at times to be less than unequivocal.").           A circuit court "is in
    a far superior position to ascertain bias than is an appellate
    court whose only link to the voir dire is through the 'bare words
    on a transcript,'" and may properly determine a prospective juror
    can be impartial despite a less than unequivocal affirmation of
    impartiality.
    Id. at 775-77
       (quoting    State   v.    Ferron,   
    219 Wis. 2d 481
    , 508, 
    579 N.W.2d 654
    (1998) (Geske, J., dissenting)).
    19
    No.   2017AP2364-CR
    ¶42       Here, the circuit court made no express finding and the
    record is devoid of any questions that could clarify whether Juror
    R.G. actually harbored any bias or, if she did, whether she was
    credibly willing to set it aside.12          See Williams, 
    364 Wis. 2d 126
    ,
    ¶79.    Gutierrez asks us to speculate as to how Juror R.G. would
    answer unasked questions.            Such speculation is insufficient to
    overcome         Juror   R.G.'s   presumed   impartiality.         See   In    re
    Gutenkunst's Estate, 
    232 Wis. 81
    , 86-87, 
    286 N.W. 566
    (1939) ("It
    was for appellant to rebut the presumption . . . in this case, and
    it is plain to us that he failed to bring the issue out of the
    field       of   speculation   and   conjecture.    This   being    true,     the
    presumption stands . . . .").           Considering the sparse record in
    this case and in light of the presumption of juror impartiality,
    the circuit court did not err by seating Juror R.G. as a juror.
    D.   Ineffective Assistance of Counsel
    ¶43       Lastly, Gutierrez argues that he was denied effective
    assistance of counsel based on his counsel's decisions not to
    further examine or exercise a peremptory strike on Juror R.G., and
    not to call Gutierrez's mother as a witness.                   Implicit in a
    criminal defendant's right to counsel is the guarantee that such
    counsel provides effective assistance.             See U.S. Const. amends.
    VI, XIV; Wis. Const. Art I, § 7; see also Strickland v. Washington,
    As the circuit court itself recognized in its oral ruling
    12
    denying postconviction relief, the better practice would have been
    to follow up with an equivocating juror to elicit more definitive
    answers to these important questions.
    20
    No.        2017AP2364-CR
    
    466 U.S. 668
    , 686 (1984) ("[T]he right to counsel is the right to
    the effective assistance of counsel." (quoted source omitted)).
    ¶44     To     demonstrate       that         counsel's     assistance          was
    ineffective, the defendant must satisfy both prongs of the test
    announced by the United States Supreme Court in 
    Strickland, 466 U.S. at 687
    .         First, the defendant must demonstrate that counsel's
    performance was deficient, which requires a showing that "counsel
    made errors so serious that counsel was not functioning as the
    'counsel' guaranteed the defendant by the Sixth Amendment."
    Id. Second, the
    defendant must show prejudice by establishing that
    "there    is     a    reasonable     probability       that,     but    for     counsel's
    unprofessional errors, the result of the proceeding would have
    been different."
    Id. at 694.
              "A reasonable probability is a
    probability sufficient to undermine confidence in the outcome."
    Id. A failure
    to satisfy either prong eliminates the need to
    consider the other.
    Id.
    at 697.
    ¶45     As to counsel's decision not to further examine or strike
    Juror    R.G.,       Gutierrez   cannot    establish      prejudice.            Prejudice
    requires that counsel's performance resulted in the seating of a
    biased juror.          See State v. Koller, 
    2001 WI App 253
    , ¶14, 
    248 Wis. 2d 259
    , 
    635 N.W.2d 838
    (citing State v. Lindell, 
    2001 WI 108
    ,
    ¶81,    
    245 Wis. 2d 689
    ,      
    629 N.W.2d 223
    ;       State    v.    Traylor,      
    170 Wis. 2d 393
    , 400–01, 
    489 N.W.2d 626
    (Ct. App. 1992)).                         This record
    does not support more than "rank speculation" that Juror R.G. was
    biased,

    ; see also Lepsch,

    , ¶37.         Because Gutierrez cannot demonstrate that he was
    21
    No.    2017AP2364-CR
    prejudiced as a result of his counsel's conduct, we need not
    address     whether       his        counsel's       performance            was     deficient.

    ¶46      Regarding counsel's decision not to call Gutierrez's
    mother    as    a   witness,         Gutierrez      cannot       demonstrate         deficient
    performance.          Deficient        performance         requires         that     counsel's
    performance fell below "an objective standard of reasonableness."
    Id. at 688.
            Gutierrez must overcome "a strong presumption that
    counsel's      conduct      falls      within      the    wide    range       of   reasonable
    professional assistance."
    Id. at 689.
                 Our review is "highly
    deferential"        and   we    do    "not    second-guess         a    reasonable          trial
    strategy, [unless] it was based on an irrational trial tactic or
    based upon caprice rather than upon judgment." State v. Breitzman,

    ¶47      Defense counsel articulated several reasons why he opted
    not to call Gutierrez's mother as a witness at trial.                              Recognizing
    that "this was obviously a case about credibility," defense counsel
    was   concerned      that      Gutierrez's         mother's      credibility         would     be
    undermined       because       she     did    not        immediately         report     A.R.'s
    recantation and provided few details surrounding when A.R. made
    her recantation and why A.R. was with her in Texas at the time.
    Defense counsel stated that he judged Gutierrez's mother to be "a
    loose cannon" who "loved to talk" and "would just go off on
    something else" in response to any question.                                 Ultimately, he
    22
    No.   2017AP2364-CR
    decided that calling her as a witness would not benefit Gutierrez's
    case.13
    ¶48    In    a   trial    where    credibility          is   paramount,    it   is
    reasonable not to call a witness whose perceived inability to give
    clear, coherent responses may subject her to a damaging cross-
    examination.      Defense counsel was legitimately concerned that the
    jury would view the defendant calling his mother to the stand with
    an unreliable story as a desperate measure.                  Since defense counsel
    pursued     a    strategy     within     "the    wide        range    of    reasonable
    professional assistance," Gutierrez has failed to establish his
    counsel's        performance      was        unconstitutionally             deficient.
    
    Strickland, 466 U.S. at 689
    .             Absent this showing, we need not
    address his claim of prejudice.
    Id. at 697.
    IV.     CONCLUSION
    ¶49    We    conclude     that    the    court     of    appeals      erroneously
    reversed the circuit court's exercise of discretion in excluding
    unidentified DNA evidence.            We further conclude that the court of
    appeals properly affirmed the circuit court's admission of the
    other acts evidence.          Lastly, we conclude that Gutierrez was not
    denied his right to an impartial jury or his right to effective
    13Gutierrez attempts to rebut defense counsel's articulated
    rationale, citing his mother's post-trial testimony at the Machner
    hearing.   However, these later statements tell us little about
    what his counsel observed leading up to trial. See Strickland v.
    Washington, 
    466 U.S. 668
    , 689 (1984) (emphasizing the need to
    "evaluate the conduct from counsel's perspective at the time" to
    "eliminate the distorting effects of hindsight"). Moreover, the
    circuit court noted that Gutierrez's mother's testimony at the
    Machner hearing was "littered with examples of the witness
    answering unasked questions, veering away from the question asked
    to some unrelated or tangential topic all while on direct."
    23
    No.   2017AP2364-CR
    assistance of counsel.    Accordingly, we reverse the court of
    appeals' decision as to the unidentified DNA evidence and affirm
    its decision as to the other acts evidence.   We also affirm the
    circuit court's denial of Gutierrez's postconviction motion.
    By the Court.—The decision of the court of appeals is affirmed
    in part and reversed in part.
