BARNES, J.
Dr. Thompson asserts that Juror Odam’s failure to disclose an alleged bias against physicians was juror misconduct, requiring a new trial. In the alternative, Dr. Thompson argues that the trial court’s refusal to conduct a hearing outside the presence of the jury in which he could question Juror Odam to determine the extent of her alleged bias is grounds for a new trial.
A trial court has discretion to grant or deny challenges for cause. Merritt v. Evansville-Vanderburgh School Corp., 765 N.E.2d 1232, 1235 (Ind. 2002). A trial court’s decision is sustained on appeal unless it is illogical or arbitrary. Id. “When a juror serves who should have been removed for cause, the complaining party is entitled to a new trial, absent waiver.” Id. “In both civil and criminal cases the parties shall make all challenges for cause before the jury is sworn to try the case, or upon a showing of good cause for the delay, before the jury retires to deliberate.” Ind. Jury Rule 17(a). The trial court shall sustain a challenge for cause if the prospective juror is biased or prejudiced for or against a party to the case. J.R. 17(a)(8).
Here, the trial court initially explained to the prospective jurors:
each side has an opportunity to ask you questions. And so what you have just done is swear that you will answer those questions truthfully. So each side will ask you either individually or collectively different questions . . . . Each side has the right to make sure that the jury that they have for the case is not biased or prejudiced.
Tr. p. 60. Dr. Thompson posed a series of questions regarding possible bias to the panel of prospective jurors, including Juror Odam, collectively. Dr. Thompson asked:
I just want to know from everybody; does anybody have any life experiences that they have that might make them have more difficulty in being fair and impartial to Dr. Thompson simply because he is a physician. Any negative experiences with physicians by you and your close family members; anybody: Has anybody ever sued a physician?
Id. at 205. Juror Odam did not respond to this line of questioning, and Dr. Thompson did not individually question Juror Odam. Immediately after she was selected as a juror, the following exchange took place between juror Odam and the trial court:
Juror Odam: I would like to say something. He asked everybody else if they would have a problem.
The Court: Okay.
Juror Odam: And I will.
The Court: Okay.
Juror Odam: Because of being a widow myself and trying to go after the doctor for negligence, he didn’t ask me. I have a; I am going to have a hard –
The Court: Okay, well be that as it may, our system is an adversary system where people ask questions on both sides and we go accordingly, so you will be instructed on Monday morning to be a good juror, and I am sure you will be. . . .
Id. at 229.

Dr. Thompson equates Juror Odam’s silence during the collective questioning with “concealment.” . . . He characterizes Juror Odam’s actions as juror misconduct and asserts he is entitled to new trial. See Pearcy v. Michigan Mut. Life Ins. Co., 111 Ind. 59, 62, 12 N.E. 98, 100-01 (1887) (“A juror who falsely misrepresents his interest or situation, or conceals a material fact relevant to the controversy, is guilty of misconduct, and such misconduct is prejudicial to the party, for it impairs his right to challenge.”). Juror Odam, however, did ultimately disclose the possibility of bias on her part. Based on this record, we are not convinced that Juror Odam’s silence can be equated with “concealment” of a bias against physicians and juror misconduct as a matter of law.
Our analysis does not end there, however. We believe that Juror Odam’s silence when taken with her subsequent statement to the trial court was specific, substantial evidence showing a juror was possibly biased. See Lopez, 527 N.E.2d at 1130. Dr. Thompson brought this issue to the trial court’s attention in a timely manner. See J.R. 17(a). At that point, it was incumbent upon the trial court to conduct a hearing, out of the presence of the remainder of the jury, to determine: (1) whether Juror Odam’s silence indicated bias or lack of disinterest; and (2) whether the hearing itself has created a bias in the juror. See Stevens, 265 Ind. 396, 403, 354 N.E.2d 727, 732 (1976). The court should then have allowed Dr. Thompson to challenge Juror Odam for cause, and should have excused her and declared a mistrial if bias was found to be present. See id., 354 N.E.2d at 732.
The trial court did not follow this protocol; instead, it denied Dr. Thompson’s motions to strike, for a hearing, and for a mistrial based on its previous, albeit extensive, experience conducting jury trials. Although the trial court’s rulings on these motions was a matter of discretion, the trial court was not permitted to disregard the established procedure or the distinct possibility of juror bias based on Juror Odam’s own belated statement. The trial court erred by not conducting a hearing to address Juror Odam’s alleged bias.

It is common practice in Indiana to question prospective jurors collectively, and the trial court here instructed prospective jurors that they would be questioned individually or collectively. “It is the duty of each juror to answer all questions on voir dire fully and truthfully.” McFarland v. State, 271 Ind. 105, 110, 390 N.E.2d 989, 992 (1979). We see no reason why a prospective juror’s obligation to answer all questions truthfully applies with less force to questions posed the panel as a whole. Dr. Thompson did not waive the issue by questioning the panel collectively and not individually questioning Juror Odam where she gave no indication that follow-up questioning was necessary.
Likewise, we reject the Appellees’ claim that, to preserve the issue, Dr. Thompson was required to use his remaining peremptory challenge to strike Juror Odam. In Indiana, “a claim of error arising from denial of a challenge for cause is waived unless the appellant used any remaining peremptory challenges to remove the challenged juror or jurors.” Merritt, 765 N.E.2d at 1235. We cannot conclude, however, that the exhaustion rule requires a party to use an available peremptory challenge to correct an erroneous denial of a challenge for cause when a claim of bias arises after the jury has been selected. Based on Juror Odam’s silence during the collective questioning, Dr. Thompson had no reason to move to strike her, either for cause or by peremptory challenge, during the selection process. The Appellees’ reliance on the exhaustion rule is misplaced.
Under these circumstances, we believe a new trial is warranted. In Barnes v. State, 263 Ind. 320, 330 N.E.2d 743 (1975), our supreme court addressed an allegation that the defendant was prejudiced by the inaccurate voir dire answers regarding a juror who was married to a second cousin of a member of the prosecutor’s staff. Notwithstanding affidavits indicating that the staff member was not aware of the relationship at the time of trial and had not seen or heard from his cousin in eleven years, the court observed that the possibility of bias existed. Barnes, 263 Ind. at 325, 330 N.E.2d at 747. The court stated:
If the juror lied, his misconduct was ground for a new trial. If the answer was inaccurate, it prevented the defendant from investigating a possible source of future bias in favor of the prosecution. Even though the juror may not have been aware at the time of the voir dire question of his relationship, if at any time prior to the verdict he discovered such a fact; the possibility of bias existed. In such a situation the defendant would need to have the opportunity to probe the juror and, if he chose, to challenge for cause. Of course, if throughout the trial the juror never knew of the relationship there would be no error since the relationship could not have influenced his decision.
Therefore, we must remand this case to the trial court for an evidentiary hearing for a determination of the following questions:
(1) During voir dire was the juror aware of his relationship to the member of the prosecutor’s staff?
(2) At any time prior to the verdict, did the juror become aware of his relationship to the member of the prosecutor’s staff?
If either of these questions are found to require an affirmative answer, grounds for challenge for cause will have been shown to have existed, and a new trial must be ordered.
<Id. at 325-26, 330 N.E.2d at 747 (citation omitted).
The Barnes court posed two specific questions to be addressed on remand. Both questions required an objective assessment of what the juror knew and when he knew it. In that regard, the issue before us today is distinguishable from Barnes. Whether Juror Odam’s silence amounted to misconduct and whether she was in fact biased against physicians requires a more subjective assessment of the circumstances. We believe it would be difficult to assess the allegations many months after trial, and neither party requests the matter be remanded for an evidentiary hearing. Accordingly, the proper recourse is a new trial. See Merritt, 765 N.E.2d at 1237 (avoiding slippery slope of a case-sensitive analysis of whether the defendant used his peremptory challenges reasonably, or whether that juror’s bias resulted in actual, not just potential, prejudice to the defendant and adopting a brightline rule: “If on appeal you then prove both the erroneous denial and that you were unable to strike another objectionable juror because you exhausted your peremptories, you are entitled to a new trial . . . .”).
