PATIENCE DRAKE ROGGENSACK, J.
¶ 1. We review an order of the court of appeals1 affirming the [375]*375circuit court's2 order vacating a jury verdict finding David Funk (Funk) guilty of two counts of sexual assault of a child and granting him a new trial. The circuit court ordered a new trial based on its post-trial discovery that a juror, Tanya G., had not revealed during voir dire that she had been a victim of two prior incidents of sexual assault and its findings that these experiences made her biased against Funk. The issue presented in this case is whether Tanya G. was biased against Funk, thereby depriving Funk of his constitutional right to an impartial jury. This issue requires us to address three sub-issues: (1) whether Tanya G. failed to respond to a material question during voir dire, (2) whether the circuit court's finding that Tanya G. was subjectively biased against Funk was clearly erroneous, and (3) whether, as a matter of law, a reasonable judge could have concluded that a reasonable person in Tanya G.'s position could not be impartial, and therefore, Tanya G. was objectively biased against Funk.
¶ 2. We conclude that Tanya G. failed to respond to a material question during voir dire when Funk's attorney asked if anyone on the jury panel had previously testified in a criminal case. We also conclude that the circuit court's finding that Tanya G. was subjectively biased against Funk is unsupported by facts of record and is clearly erroneous. Finally, we conclude that the facts necessary to ground a circuit court's reasonable legal conclusion that a reasonable person in Tanya G.'s position could not be impartial were not developed in this case, and therefore the circuit court's conclusion that Tanya G. was objectively biased was erroneous. Accordingly, we reverse the court of appeals order and reinstate the guilty verdict and judgment of conviction.
[376]*376I. BACKGROUND
¶ 3. Funk was charged with two counts of sexual assault of a child under 13 years of age, contrary to Wis. Stat. § 948.02(1) (2005-06).3 The charges were based on two encounters with C.M.F., who at the time was ten years of age. Specifically, Funk was alleged to have performed oral sex on C.M.F. and also to have anally penetrated the young girl. The alleged incidents occurred at C.M.F.'s home when her mother was at work. At the time, Funk was the boyfriend of C.M.F.'s mother.
¶ 4. In late April of 2008, Funk was tried to a jury for the assaults of C.M.F. Relevant to the issue in this case is what occurred during voir dire. First, toward the beginning of voir dire, the court highlighted the nature of the case and noted that the jurors would be asked whether they, themselves, or someone they knew, had ever been a victim of sexual assault. The court emphasized that the jurors could discuss any sensitive issues in chambers:
Now, one of the questions is going to be, I believe is, have anyone of you been a victim of sexual assault, or a brother or sister who's been sexually assaulted; possibly a neighbor of sexual assault?
With respect to that question, to be quite frank with you, if somebody asked me, have you ever been a [377]*377victim of sexual assault, I wouldn't answer it, but you are under oath; maybe it's a brother or a sister, maybe it's a neighbor, or maybe it's yourself.
We could go into chambers, if you wish to; we certainly don't have to. You need to be honest. You need to answer the question, and what we will do is to avoid any embarrassment, we can go into chambers.
Despite the court's proclamation that these questions would be asked, neither the court nor the attorneys asked whether any juror had been a victim of sexual assault or whether any juror knew someone who had been a victim of sexual assault.
¶ 5. Other questions asked by the parties, however, did lead to the disclosure by some jurors that they personally, or someone they knew, had been a victim of sexual assault. For example, the State asked: "Have you, or any of your family members, or close friends ever been accused of a crime by law enforcement?" In response to this question, Juror E.4 disclosed that he had a friend who had been accused of a crime in a "situation like this." The State asked to question Juror E. in chambers. In chambers, Juror E. disclosed that a close friend of his had recently been caught trying to entice underage girls into having sexual relations, but assured the court he could still be fair and impartial to Funk. The court did not excuse Juror E.
¶ 6. The State also asked: "Now, this case, as Judge Roemer noted, involves allegations of sexual assault of a child. Based upon those allegations, those charges, does anyone here believe they would have a difficult time being fair and impartial both to the State and to the Defendant?" In response to this question, two [378]*378jurors asked to speak privately in chambers. Juror G. disclosed in chambers that when she was nine or ten, she was sexually molested by a family member. She stated that it would be very difficult for her to put this experience aside if she were picked to sit on the jury. The court excused Juror G. The other juror, Juror J., disclosed that her granddaughter had been sexually assaulted and that there was currently a trial going on in Florida related to the assault. She said she did not know if she could be fair and impartial to Funk. The court excused Juror J.
¶ 7. The court replaced the two excused jurors.5 The State asked the two new jurors if they would have answered any of the previous questions affirmatively. Both jurors responded by requesting to go into chambers. Of the two new jurors, one disclosed that he had heard about the case. The court did not excuse the juror based on this information. The other new juror, Juror D.,6 disclosed that her ex-husband was raped when he was 14. She stated that she would rather not sit on the jury. Consequently, Juror D. was excused from service.
¶ 8. Juror S. replaced Juror D. Juror S. was similarly questioned about whether he would have answered affirmatively to any of the previous questions. Juror S. asserted that he would have, but that he did not need to go into chambers to discuss the answer privately. He then stated, in open court, "It has to do with knowing someone about a sexual assault case. My [379]*379uncle went to prison for it, and I don't think I could be fair to the party." The court excused Juror S.
¶ 9. In addition to the above questions asked by the State, the panel was asked several other times if any juror believed he or she could not be fair to Funk or the State.7 These questions did not lead to any further assertions of partiality.
¶ 10. Of particular importance, Funk's attorney asked if any juror had ever testified as a witness before: "Anyone ever go to court to testify in a criminal case as a witness? Anyone ever go to court to testify in a civil case as a witness?" While numerous jurors answered "yes" to this question and explained the circumstances under which they had testified, Tanya G. did not respond. The State also asked if anyone had ever had contact with the Juneau County District Attorney's Office. Several jurors responded in the affirmative to this question. Similarly, Tanya G. remained silent when this question was asked. A review of the [380]*380voir dire transcript shows that Tanya G. did not respond individually8 to any question posed during voir dire.
¶ 11. Tanya G. was selected to sit on the jury. During the two-day trial, C.M.F. testified about the assaults. Moreover, both N.M.F., Funk's 13-year-old daughter, and A.M.F., Funk's 14-year-old daughter, testified, corroborating much of C.M.F.'s story.9 The jury convicted Funk of both counts of sexual assault of a child under 13 years of age.
¶ 12. Sometime after the trial, Funk learned that Tanya G. had been a victim of sexual assault. Consequently, several days before his scheduled sentencing, Funk moved to vacate the judgment of conviction and for a new trial on the grounds that Tanya G. was biased against him, and therefore, he had been deprived of his constitutional right to an impartial jury. According to Funk's motion, Tanya G. was the victim in an 18-count sexual assault case that occurred in 1998.
¶ 13. The 1998 sexual assaults occurred when Tanya G. was ten years old and involved Tanya G.'s school-bus driver touching her private areas when she would get on and off the bus. The abuse happened on numerous occasions and Tanya G.'s two younger sisters were also victims. Tanya G. reported the abuse to the authorities and was questioned by a Juneau County detective about the assaults.
[381]*381¶ 14. Subsequent to Funk's motion to vacate the judgment, it was also learned that Tanya G. had been the victim of a sexual assault that occurred in January of 2005. According to the criminal complaint issued for the 2005 incident, Tanya G. was at a party when the perpetrator, Julian C., locked Tanya G. in a bedroom and forced her to have sexual intercourse with him. Tanya G. testified during the preliminary hearing in the case against Julian C. Following the preliminary hearing, Julian C. pled no contest and was sentenced. Tanya G. was 17 years old at the time of the assault by Julian C.
¶ 15. In response to this newly discovered information about Tanya G., the circuit court held a post-conviction evidentiary hearing at which Tanya G. testified. At the hearing, Tanya G. confirmed that her elementary-school bus driver had sexually molested her. She explained that the abuse started when she was in kindergarten and that it occurred "every day" she rode the bus from kindergarten through third grade. Moreover, Tanya G. testified that she witnessed the bus driver abuse her two younger sisters. Tanya G. reported the abuse to the authorities, but the record does not reflect that she testified in any proceeding related to the abuse. Tanya G. also confirmed at the post-conviction hearing that she had been raped by Julian C. when she was 17 years old.
¶ 16. The circuit court questioned Tanya G. about whether the allegations against Funk made her uncomfortable:
[The Court]: Now, the question I have for you is, when you heard what the allegations were involving Mr. Funk, did you feel uncomfortable at that point in time?
[Tanya G.]: No.
[382]*382[The Court]: You didn't feel uncomfortable whatsoever?
[Tanya G.]: No.
The court then asked Tanya G. why she did not disclose each specific incident of sexual assault. With regard to the sexual assault by the bus driver, Tanya G. responded that she did not think she was allowed to talk about it because, under the settlement agreement in the case, her lawyer had told her that if she talked about it, she would be fined $5,000.10 Her explanation for why she did not disclose that her sisters had been victims of sexual abuse was: "I understand that I should have said something, but since my sisters have nothing else on their records indicating sexual assault, I wasn't allowed to put them in jeopardy."
¶ 17. With regard to the assault by Julian C., Tanya G. stated that she did not disclose the incident to the court "[b]ecause it's my past. I don't go from day to day saying that this guy raped me, he did this. It's not the way I live my life. I put it in the back of my head, and I don't reveal it ever again."
¶ 18. At the post-conviction hearing, Tanya G. consistently denied that the nature of the allegations against Funk caused her to recall her past experiences with sexual assault during Funk's trial, or that she had prejudged Funk in any way.11 She also noted that she did not discuss that she had been a victim of sexual assault with any other jurors. Tanya G. was never asked [383]*383why she did not respond to the question about whether any juror had been a witness in a criminal case.
¶ 19. The circuit court expressed its difficulty in understanding Tanya G.'s answers. The court said, "it's not so much that I'm not taking you at face value, but I [384]*384just have a hard time understanding, but it seems to me that the incidences that involved you would probably be some of the most devastating of a person's life."
¶ 20. Following the post-conviction hearing and a review of the voir dire transcript, the circuit court determined that at no time during voir dire was the question asked: " 'Have you been a victim of a sexual assault,' or, 'Have you or your family been victims of sexual assault?'" However, the court concluded that Tanya G. did not respond to a material question when Funk's attorney asked whether anyone had testified as a witness in a criminal case. This, the court concluded, was an incorrect answer given that Tanya G. had testified at Julian C.'s preliminary hearing.
¶ 21. The court then concluded that Tanya G. was both subjectively and objectively biased. With respect to subjective bias, the court opined:
I have a very difficult time when an individual takes the voir dire oath, and I am not going to recite it, but swears to tell the truth, the whole truth to questions asked of you to a very solemn occasion, there's a black-robed man up here, and she did not answer affirmatively to the question of whether she was a victim of assault, or more specifically, as I've previously found, that she could not recall these incidences.
Now, I'm not calling Tanya [G.] a liar. I believe all of us view things through [] a certain prism, but I have a very exceedingly, exceptionally difficult time finding subjectively that this woman who, as a young child, and who has as a young woman, been sexually assaulted, and hearing the testimony of three children, who, as one who was sexually assaulted, she didn't put that aside. So, subjectively, I do find there is bias.
[385]*385¶ 22. With respect to objective bias, the court noted that simply because Tanya G. was a victim of sexual assault, she was not precluded from sitting on the jury. Rather, the court considered whether "a reasonable person in [Tanya G.'s] position, could they be impartial, objectively?" In its analysis, the court compared the sexual assaults inflicted upon Tanya G. with the sexual assaults at issue in Funk's case. The court noted that Tanya G. was assaulted by her bus driver at approximately the same age as C.M.F., when Funk's alleged assaults occurred. The court also pointed out that Tanya G.'s sisters were sexually assaulted at the same young age, and noted that in Funk's case, both of Funk's daughters, who referred to C.M.F. as their "sister," had testified.
¶ 23. In addition, the court noted that Tanya G. was sexually assaulted again when she was 17. The court then concluded, "I believe that objectively when I look at the case that was tried, I look at this juror's past, objectively I find that the juror could not be fair and impartial." As a result of the circuit court's conclusion that Tanya G. was biased against Funk, the court vacated Funk's guilty verdict and judgment of conviction and ordered a new trial.
¶ 24. The State appealed. The court of appeals affirmed in an unpublished order. State v. Funk, No. 2008AP2765-CR, unpublished order (Wis. Ct. App. Apr. 28, 2010). On appeal, the State argued that the circuit court improperly found that Tanya G. failed to answer a material question because Funk's motion focused on whether Tanya G. failed to answer whether she had been a victim of sexual assault, when no such question was asked of the jury panel. Id. at 6. The court of appeals rejected this argument, relying on Tanya G.'s failure to answer several questions correctly, "including [386]*386whether she had any past contacts with the district attorney's office and any prior involvement in a civil case, as well as whether she had testified in a criminal case." Id. at 7.
¶ 25. Moving to subjective bias, the court of appeals rejected the State's argument that the circuit court was actually applying an objective test. Id. at 8. Instead, it concluded that "[l]ooking at all of the court's comments together, we are persuaded that the court was in fact rejecting Tanya G.'s testimony that she did not recall or think about any of her own past experiences of sexual assault or involvement in the court cases stemming from them." Id. In other words, Tanya G. "was simply not credible." Id. at 9.
¶ 26. The court of appeals did not address objective bias, noting that its affirmation of the circuit court's findings that Tanya G. incorrectly answered a material question and that she was subjectively biased was sufficient to support the circuit court's exercise of discretion. Id. at 9-10.
¶ 27. Judge Lundsten filed a dissenting opinion in which he concluded that the circuit court "misapprehended what is required for findings of subjective bias and objective bias." Id. at 10. Namely, when analyzing subjective bias, Judge Lundsten concluded that the circuit court disregarded Tanya G.'s explanations and answers and instead substituted its own judgment as to how a person in Tanya G.'s position should have felt. Id. at 10-11. In his brief discussion of objective bias, Judge Lundsten declared that "[i]t is sufficient to say that I conclude that the pertinent voir dire questions were so inartfully posed that Tanya G.'s non-answers cannot reasonably be used to support a finding of objective bias." Id. at 11.
[387]*387¶ 28. We granted review and now reverse the court of appeals.
II. DISCUSSION
A. Standard of Review
¶ 29. We address whether juror Tanya G. was biased against Funk thereby depriving him of his constitutional right to an impartial jury. In so doing, we determine whether Tanya G. was subjectively or objectively biased against Funk. See State v. Faucher, 227 Wis. 2d 700, 716, 596 N.W.2d 770 (1999); State v. Wyss, 124 Wis. 2d 681, 726, 370 N.W.2d 745 (1985), overruled on other grounds by State v. Poellinger, 153 Wis. 2d 493, 451 N.W.2d 752 (1990). Whether a juror was asked certain questions and incorrectly or incompletely responded to those questions is an issue of fact that we will not reverse unless it is clearly erroneous. State ex rel. Pharm v. Bartow, 2007 WI 13, ¶ 12, 298 Wis. 2d 702, 727 N.W.2d 1; see also State v. Casey, 166 Wis. 2d 341, 348, 479 N.W.2d 251 (Ct. App. 1991). However, whether the question at issue is "material" is a question of law that we review independently. See Pharm, 298 Wis. 2d 702, ¶ 12.
¶ 30. "[W]e will uphold the circuit court's factual finding that a prospective juror is or is not subjectively biased unless it is clearly erroneous." Faucher, 227 Wis. 2d at 718. Objective bias, on the other hand, is a mixed question of fact and law. Id. at 720. "[A] circuit court's findings regarding the facts and circumstances surrounding voir dire and the case will be upheld unless they are clearly erroneous. Whether those facts fulfill [388]*388the legal standard of objective bias is a question of law." Id. Although we do not defer to a circuit court's decision on a question of law, where the factual and legal determinations are intertwined as they are in determining objective bias, we give weight to the circuit court's legal conclusion. We have said that we will reverse a circuit court's determination in regard to objective bias "only if as a matter of law a reasonable judge could not have reached such a conclusion." Id. at 720-21.
B. Principles for Assessing Juror Bias
¶ 31. The Sixth Amendment of the United States Constitution12 and Article I, Section 7 of the Wisconsin Constitution13 guarantee criminal defendants the right to an impartial jury. Moreover, principles of due process under which a defendant is to be judged solely on evidence adduced at trial also protect a criminal defendant's right to an impartial jury. State v. Kiernan, 227 Wis. 2d 736, 750, 596 N.W.2d 760 (1999). "Prospective jurors are presumed impartial." State v. Louis, 156 Wis. 2d 470, 478, 457 N.W.2d 484 (1990). The party challenging a juror's impartiality bears the burden of rebutting this presumption and proving bias. Id.
[389]*389¶ 32. When we are asked to assess juror bias, we employ a two-step test developed in Wyss. Under that test, in order to be granted a new trial, a litigant must prove:
(1) that the juror incorrectly or incompletely responded to a material question on voir dire; and if so, (2) that it is more probable than not that under the facts and circumstances surrounding the particular case, the juror was biased against the moving party.
Wyss, 124 Wis. 2d at 726.
¶ 33. Under the first step of the Wyss test when, as is the case here, there is no factual dispute about what was asked and answered during voir dire,14 the issue we address is whether the question incorrectly or incompletely answered is material. We have not previously had the opportunity to fully articulate what constitutes a material question. However, our rationale in Wyss for rejecting the two-step test set forth by the Supreme Court in McDonough Power Equipment, Inc. v. Greenwood, 464 U.S. 548 (1984), provides insight into what constitutes a material question.
¶ 34. Pursuant to the McDonough test, the challenging party has to " 'first demonstrate that a juror failed to answer honestly a material question on voir dire, and then further show that a correct response would have provided a valid basis for a challenge for cause.'" Wyss, 124 Wis. 2d at 721 (quoting McDonough, 464 U.S. at 556). We rejected this approach in Wyss because we believed it to be too limited. Id. at 727-28. [390]*390We explained that under the McDonough test, circumstances could arise where a juror's honest response to a question he or she incorrectly or incompletely responded to during voir dire may not, in and of itself, be enough to provide a valid basis to challenge the juror for cause. Nonetheless, if the question had been answered correctly at voir dire, it may have led to further questioning that would have provided a valid basis to challenge for cause. In other words, as we opined, "a narrow reading of McDonough fails to take into account the very real possibility that a correct and/or complete answer, although not providing a basis for challenge itself, may well provide the basis for further questions and responses that do uncover bias." Id. at 729.15
[391]*391¶ 35. While this discussion in Wyss was used as support for our rejection of the second step of the McDonough test, it also is telling about what constitutes a material question under the Wisconsin juror bias test. Our discussion demonstrates that it is important to consider follow-up questions that would likely have been asked had the juror answered the asked question correctly. Consequently, material questions are not only those questions to which the direct or immediate answer reveals a juror's bias. Rather, if the defendant proves that the question and its correct answer would have incited further inquiry, inquiry that would likely have uncovered bias, we consider the initial question to be material. Stated another way, if the question the juror incompletely and/or incorrectly answered is of consequence to the determination of bias, it is material.
¶ 36. In Faucher, we engaged in a thorough analysis of the three types of juror bias: statutory bias, subjective bias, and objective bias.16 Faucher, 227 [392]*392Wis. 2d at 717-19. The only issues presented in this case are whether Tanya G. was subjectively or objectively biased.17
¶ 37. The inquiry into whether a juror is subjectively biased is focused on the specific juror's state of mind. Id. at 718. Jurors are subjectively biased when they have "expressed or formed any opinion" about the case prior to hearing the evidence. Id. at 717. A juror may reveal his or her subjective bias either through words, namely his or her explicit assertion of bias or partiality, through demeanor, or through a combination of the two. Id.; see also State v. Lindell, 2001 WI 108, ¶ 36, 245 Wis. 2d 689, 629 N.W.2d 223. "While there may be the occasion when a prospective juror explicitly admits to a prejudice, or explicitly admits to an inability to set aside a prejudice, most frequently the prospective juror's subjective bias will [] be revealed [only] through his or her demeanor." Faucher, 227 Wis. 2d at 718. When subjective bias is evidenced by a juror's demeanor, the circuit court's assessment will often rest on its analysis of the juror's honesty and credibility. Id.
¶ 38. Objective bias, on the other hand, shifts the inquiry from the specific juror's state of mind to an inquiry into "whether [a] reasonable person in the individual prospective juror's position could be impartial." Id. The focus is on the facts and circumstances surrounding the voir dire and trial, and whether given [393]*393those facts and circumstances, a reasonable person in the juror's position would be biased. Id. at 718-19.
¶ 39. In cases involving a juror who was not forthcoming during voir dire and subsequently sat on the jury, a circuit court is to consider the following three, non-exclusive, factors to determine objective bias:
(1) did the question asked sufficiently inquire into the subject matter to be disclosed by the juror;
(2) were the responses of other jurors to the same question sufficient to put a reasonable person on notice that an answer was required;
(3) did the juror become aware of his or her false or misleading answers at anytime during the trial and fail to notify the trial court?
Id. at 727 (quoting Wyss, 124 Wis. 2d at 731).18 We [394]*394examine these questions because a juror's responses under the facts and circumstances of a particular case [395]*395must be compared with those of a reasonable person in the position of the juror. State v. Delgado, 223 Wis. 2d 270, 281-82, 558 N.W.2d 1 (1999).
¶ 40. Sexual assault cases can be difficult for any juror. However, the "failure of a juror in a sexual assault case to answer correctly or completely a question during voir dire about his or her experience of sexual assault does not constitute bias per se." Id. at 282; see also State v. Erickson, 227 Wis. 2d 758, 777, 596 N.W.2d 749 (1999). The answers to the questions suggested in Wyss and Delgado will provide insight into whether the juror was so emotionally affected by the prior sexual assault that a reasonable person in the juror's position could not be impartial. Delgado, 223 Wis. 2d at 285-86. In our review, we perform an independent application of these factors to the facts and circumstances of the case to determine whether the juror was objectively biased as a matter of law. See id. at 283-85.
C. Application
a. Material question
¶ 41. We now apply the legal standards set forth above to the facts and circumstances of this case. Beginning with the first step of the two-step Wyss test, we agree with the circuit court and court of appeals that [396]*396Tanya G. failed to answer defense counsel's questions: "Anyone ever go to court to testify in a criminal case as a witness? Anyone ever go to court to testify in a civil case as a witness?"
¶ 42. Moreover, given the facts of this case, this question was material. Funk's argument throughout has been that Tanya G. was biased based on her previous experiences as a victim of sexual assault. Had Tanya G. correctly responded when asked if she had testified in a criminal case, this would likely have incited further questioning that may have uncovered that Tanya G. had been a victim of sexual assault.
¶ 43. The likelihood that an affirmative response by Tanya G. may have led to the eventual disclosure that she had been a victim of sexual assault is evidenced by the responses of the other jurors to this question. When Funk's attorney asked whether anyone on the panel had testified as a witness, four jurors answered in the affirmative. All four disclosed the nature of the case in which he or she had testified, either in their initial answer to the question or in response to a follow-up question by Funk's attorney. Consequently, had Tanya G. correctly, and affirmatively, responded to that question, putting the court on notice that she had previously testified in a criminal case, it is likely Funk's attorney would have asked Tanya G. details about the nature of the case in which she testified. The court, therefore, would have discovered that the case was a sexual assault case and that Tanya G. was the victim of that assault. As such, the question was of consequence to the bias determination at issue here and is material.
b. Subjective bias
¶ 44. Moving to the second step of Wyss, whether Funk proved that it was more probable than not that [397]*397under the facts and circumstances surrounding this case, Tanya G. was biased against him, we first address subjective bias. The question that Tanya G. did not answer was whether she had been a witness in a criminal case. However, at the post-conviction hearing, no one asked her why she did not respond to that question. Therefore, there is no record of why she failed to answer. All of the questioning of Tanya G. in the post-conviction hearing focused on why she had not revealed that she was a victim of sexual assault. However, no question about being the victim of sexual assault was asked during voir dire.
¶ 45. As explained above, the inquiry required by law to determine whether Tanya G. is subjectively biased is focused on her state of mind. Faucher, 227 Wis. 2d at 718. A juror may reveal subjective bias by an explicit assertion of bias. Id. at 717. Tanya G. did not say that she was biased against Funk. To the contrary, Tanya G. explicitly and consistently asserted at the post-conviction evidentiary hearing that she was not biased against Funk. See, e.g., supra note 11. Moreover, during voir dire, Tanya G. never indicated she was biased against Funk despite the panel being asked numerous times whether anyone would have difficulties being impartial.
¶ 46. Subjective bias also may be revealed through a juror's demeanor, with a determination of bias resting on whether the circuit court finds the juror credible. Faucher, 227 Wis. 2d at 718. Given this standard, the circuit court's explanation for its finding that Tanya G. was subjectively biased is difficult to understand. In the portion of the circuit court's oral decision that explained its finding, the circuit court did not describe Tanya G.'s demeanor, either at voir dire or at [398]*398the post-conviction hearing, and explain how her demeanor demonstrated to the court that she was biased. Instead, the circuit court expressed its belief in her responses: "Now, I'm not calling Tanya [G.] a liar. I believe all of us view things through [] a certain prism."
¶ 47. The court then found Tanya G. subjectively biased based on Tanya G.'s failure to answer a question that was never asked and the court's own belief that someone in Tanya's position could not be impartial:
I have a very difficult time when an individual takes the voir dire oath, and I am not going to recite it, but swears to tell the truth, the whole truth to questions asked of you to a very solemn occasion, there's a black-robed man up here, and she did not answer affirmatively to the question of whether she was a victim of assault, or more specifically, as I've previously found, that she could not recall these incidences.
I have a very exceedingly, exceptionally difficult time finding subjectively that this woman who, as a young child, and who has as a young woman, been sexually assaulted, and hearing the testimony of three children, who, as one who was sexually assaulted, she didn't put that aside. So, subjectively, I do find there is bias.
¶ 48. Assessing what someone in Tanya G.'s position could or could not have done is not the correct standard on which to decide whether a juror is subjectively biased. See Faucher, 227 Wis. 2d at 718. A finding of subjective bias must be based on factual findings that show the specific juror's state of mind. Id. No such findings were made here. To the contrary, the circuit court stated that it believed Tanya G.'s assertion that she was impartial. The court also did not make any [399]*399findings about her demeanor that indicated subjective bias. Rather, the court determined that Tanya G. was subjectively biased based on her failure to answer a question that was never asked and its finding that someone who had been sexually assaulted in the manner that Tanya G. was, could not be impartial in a sexual assault trial. Accordingly, the circuit court's finding that Tanya G. was subjectively biased against Funk is not supported by facts of record and is clearly erroneous.
c. Objective bias
¶ 49. Next, we turn to objective bias and conclude that the circuit court erred as a matter of law when it concluded that Tanya G. was objectively biased against Funk. Objective bias exists when a reasonable person in the juror's position could not be impartial. Id. The fact that a juror has been a victim of sexual assault does not make him or her per se biased against the defendant in a sexual assault case. Delgado, 223 Wis. 2d at 285.
¶ 50. Delgado is instructive as we consider whether Funk has proved objective bias. As aforementioned, in deciding whether there was objective bias in Delgado, we considered the following three nonexclusive factors:
(1) did the question asked sufficiently inquire into the subject matter to be disclosed by the juror;
(2) were the responses of other jurors to the same question sufficient to put a reasonable person on notice that an answer was required;
(3) did the juror become aware of his or her false or misleading answers at anytime during the trial and fail to notify the trial court?
[400]*400Id. (citing Wyss, 124 Wis. 2d at 731); see also Faucher, 227 Wis. 2d at 727.
¶ 51. In Delgado, the defendant was tried for first-degree sexual assault of two young girls, aged seven and nine. Id. at 273. Similar to the case at hand, in Delgado, sometime after the defendant was found guilty of the crime, it came to the court's attention that one of the jurors, Juror C., had herself been a victim of sexual assault, but did not disclose this during voir dire.19 Id. at 276. The circuit court held two evidentiary hearings on the defendant's motion for a new trial to determine whether, under the facts and circumstances surrounding the case, the two-step Wyss test was satisfied.20 Id. at 276-78. During the first hearing, Juror C. explained why she did not respond to the questioning that related to being the victim of sexual assault. Id. at 276. At the second hearing, evidence was presented demonstrating that during jury deliberations, Juror C. indicated that she had previously been a victim of [401]*401sexual assault. Id. at 278. After listening to the evidence presented at the second hearing, the circuit court concluded that Juror C. was impartial and therefore, the second step of Wyss was not satisfied. Id. at 278-79.
¶ 52. On review, we noted that the circuit court did not consider the three factors set out above.21 We conducted an independent review of the facts and circumstances of Delgado as they applied to the three factors. Id. at 283-86. Based on our independent review, we concluded Juror C. was objectively biased, and we ordered a new trial. Id.
¶ 53. With regard to the first factor, whether the question asked sufficiently inquired into the subject matter to be disclosed by the juror, the panel in Delgado was explicitly asked whether anyone in the panel had been a victim of sexual assault. The exact question was: "Are there any members of the jury panel who either have a close friend or close relative or you yourself who have been the victim of a sexual assault, either as a child or as an adult?" Id. at 283. Juror C. remained silent. Id. at 275. We agreed with the court of appeals that this explicit question inquired into the jurors' prior personal experiences with sexual assault and that "[n]othing in the record supported] a conclu[402]*402sion that the phraseology of the question justified [JJuror C.'s silence." Id. at 284.
¶ 54. With regard to Delgado's consideration of the second factor, whether the responses of other jurors to the same question sufficiently put a reasonable person on notice that an answer was required, we opined that the only reasonable conclusion was that Juror C. was put on such notice. Id. Specifically, we pointed out that during voir dire, four jurors, in response to the above question and in open court, divulged that a close friend or relative had been sexually assaulted. Id.; see also Id. at 275.
¶ 55. With regard to the third factor, whether Juror C. became aware of her false or misleading answers at any time during the trial and failed to inform the trial court, we noted that Juror C. became aware of her failure to answer the question during jury deliberations. Id. at 284. As the post-conviction evidentiary hearing revealed, during deliberations Juror C. became angry with one of the other jurors who did not think the State had proved its case against the defendant. Through anger, she disclosed her prior experience with sexual assault, stating, "You don't know what it feels like, but I happen to know what it feels like to be taken advantage of." Id. at 278. The holdout juror replied by asking Juror C. why she did not report the abuse during voir dire. Id.
¶ 56. After considering the three factors for assessing whether the juror was biased, as well as the facts and circumstances of the case,22 we concluded that [403]*403Juror C.'s emotional involvement with the case caused her to be objectively biased. Id. at 285-86. We stated:
The probability that [J]uror C.'s substantial emotional involvement would adversely affect her impartiality was high. Her emotional involvement was demonstrated by the close similarity of her experience with the crimes charged, her incorrect and incomplete responses during voir dire, her revelation of her experience during jury deliberations, and her failure to report her omission to the court.
Id.
¶ 57. While Delgado is factually similar to the case at hand because both cases are sexual assault cases and involved a juror who failed to disclose during voir dire that she had been a victim of sexual assault, our review of the facts and circumstances of this case, in light of the three factors for assessing juror bias, requires a conclusion opposite from the one reached in Delgado. First, unlike the factual underpinnings of Delgado, the questions asked of Tanya G. during voir dire did not involve whether any juror had been a victim of sexual assault. Furthermore, at the post-conviction evidentiary hearing, Tanya G. was never asked why she did not respond to the question about whether any juror had been a witness in a criminal case, which was the question asked in voir dire to which she did not respond. Therefore, Funk did not make a record at the post-conviction hearing of why Tanya G. failed to answer the question that was asked. It was his burden to do so in order to fully evaluate Tanya G.'s potential bias against him. Id. at 278 (citing Wyss, 124 Wis. 2d at 726). Put another way, the questions asked at the post-conviction hearing do not provide a foundation on [404]*404which to conclude that a reasonable person in Tanya G.'s position could not impartially decide Funk's case.
¶ 58. To explain further, looking at the first factor, the questions asked of Tanya G. during voir dire did not sufficiently inquire into the subject matter of sexual assault. The material question that Tanya G. failed to answer was whether she had testified in a criminal case. This question cannot be said to sufficiently inquire into the jurors' prior personal experiences with sexual assault, which is the basis on which a new trial was ordered by the circuit court. That this unanswered question could have led to questions about sexual assault is insufficient because Tanya G. was never asked at the post-conviction hearing why she failed to respond to the question actually asked at voir dire. The overarching question when evaluating Funk's claim of objective bias is whether a reasonable person in Tanya G.'s position could be impartial. This analysis requires us to consider whether a reasonable person who had a similar level of emotional involvement with hearing the testimony about sexual assault as Tanya G. had could be impartial. The juror's level of emotional involvement is part of the "position" in which we place the reasonable person for our analysis. Tanya G.'s failure to answer the question about testifying in a criminal case, with no explanation for her silence, however, gives us no insight into whether, because of her prior experiences with sexual assault, she was emotionally involved in Funk's case and therefore unable to objectively evaluate the evidence. In other words, we are unable to place a "reasonable person" in Tanya G.'s "position" because we do not know the relevant factors that relate to her "position."
¶ 59. With regard to the second factor, the responses of the other jurors during voir dire would not [405]*405have put a reasonable juror in Tanya G.'s position on notice that she was required to disclose that she had previously been a victim of sexual assault.23 When the circuit court proclaimed during the beginning of voir dire that one of the questions was going to be whether anyone on the panel had been a victim of sexual assault or knew someone who had been a victim of sexual assault, no one in the jury panel took this proclamation as a question that needed to be answered. The record shows that although one juror herself was a victim of sexual assault and numerous jurors on the panel knew someone who had been a victim of sexual assault, no juror responded to the circuit court's proclamation by disclosing information about sexual assault. Rather, most of the information about sexual assault came out later in voir dire in response to the attorneys' more general questions about whether those on the panel could be impartial. If Tanya G. felt she could be impartial, there was no reason for her to respond to those general questions.24
[406]*406¶ 60. On the other hand, the responses of other jurors to the question about whether anyone had testified in a criminal case would have put a reasonable juror in Tanya G.'s position on notice that an answer to that question was required. Four jurors responded, and in their responses, they explained the case in which they testified. These responses would have put a reasonable juror in Tanya G.'s position on notice that she should have disclosed her prior testimony. However, at the post-conviction hearing, Tanya G. was never asked why she did not answer that question.25 Perhaps she [407]*407understood that question in a way that required no answer or perhaps she was not paying attention and missed the question all together. The record provides no information in that regard. Simply failing to answer a question during voir dire is insufficient to prove juror bias. Delgado, 223 Wis. 2d at 282.
¶ 61. Finally, in regard to the third factor, unlike Juror C. in Delgado, there is nothing in the record indicating that Tanya G. became aware of her failure to answer the question relating to serving as a witness in a criminal case at any time during Funk's trial. Even more, this case is nothing like Delgado in which Juror C.'s outburst during deliberations that "I happen to know what it feels like to be taken advantage of," id. at 278, clearly indicates that Juror C.'s experience as a previous victim of sexual assault influenced how she viewed the case (and she was arguably using this experience to influence other jurors).
¶ 62. Accordingly, an application of the three factors to the facts and circumstances of this case gives us no insight about why Tanya G. failed to respond when the panel was asked if anyone had testified as a witness in a criminal case. The failure to answer a question on voir dire is not sufficient to conclude Tanya G. was objectively biased against Funk. Id. at 282. And, the failure to answer the question asked gives us insufficient information to conclude how a reasonable person in Tanya G.'s circumstances would have acted in regard to bias against Funk.
¶ 63. In sum, jurors are presumed impartial, and Funk had the burden of rebutting this presumption and [408]*408proving Tanya G.'s bias in this case. Louis, 156 Wis. 2d at 478. We agree with Judge Lundsten that the questions asked of Tanya G. were "so inartfully posed that Tanya G.'s non-answers cannot reasonably be used to support a finding of objective bias." Funk, No. 2008AP2765-CR, unpublished order, at 11. As such, Funk has not met his burden because there is no proof that a reasonable juror in Tanya G.'s position could not be impartial. Without such proof, the only basis on which we could conclude that she was objectively biased is to conclude she was per se biased against Funk. Delgado forbids such a per se bias rule based solely on having been the victim of sexual assault. Delgado, 223 Wis. 2d at 285. Consequently, we hold that Funk has not met his burden to prove that Tanya G. was objectively biased. Stated otherwise, the facts necessary to ground a circuit court's reasonable legal conclusion that Tanya G. was objectively biased were not developed in this case.26 Therefore, the circuit court erred as a matter of law in concluding that a reasonable person in Tanya G.'s position could not be impartial.
III. CONCLUSION
¶ 64. We conclude that Tanya G. failed to respond to a material question during voir dire when Funk's attorney asked if anyone on the jury panel had previously testified in a criminal case. We also conclude that the circuit court's finding that Tanya G. was subjectively biased against Funk is unsupported by facts of record and is clearly erroneous. Finally, we conclude that the facts necessary to ground a circuit court's [409]*409reasonable legal conclusion that a reasonable person in Tanya G.'s position could not be impartial were not developed in this case, and therefore the circuit court's conclusion that Tanya G. was objectively biased was erroneous. Accordingly, we reverse the court of appeals order and reinstate the guilty verdict against Funk.
By the Court. — The decision of the court of appeals is reversed.
