delivered the opinion of the Court.

People v.
Beeman,
I.
During the trial, one of the jurors informed the bailiff that there was a possibility that she knew the defendant. The defendant thereupon moved for a mistrial and, the trial judge held an
in camera
examination to determine if the juror should be disqualified for bias.
See
section 16-10-103(j), C.R.S. 1973;
cf. Hopkins
v. People,
At the in camera hearing, the juror stated that she believed the defendant may have been a man who had greatly upset her pregnant daughter. Her testimony was that this man had come to the daughter’s home to discuss the sale of a home freezer food plan, but rather than discussing the food plan the man had talked about politics and the future of the world. Although there were no sexual implications to this meeting, the daughter was so upset that several days later the juror felt compelled to call the man’s employer and complain. It was further disclosed that the juror thought it possible that a pearl handled knife allegedly used in the rape was the knife that was missing from her daughter’s home.
During the examination, the judge questioned the juror about her capacity to act impartially in this case, and she gave assurances of her ability and desire to decide the case fairly. The judge thereupon denied the defendant’s motion for a mistrial and the juror resumed her place on the jury.
The impartiality of jurors is a fundamental aspect of the Anglo-American conception of trial by jury,
see Irvin v.
Dowd,
The enormous practical problems involved in these assessments have led to our vesting of great discretion in the trial court,
see People
v.
McCrary,
The placing of this discretion in the trial judge does not, however, permit appellate courts to abdicate their responsibility to ensure that *340 the requirements of fairness are fulfilled. At some point this court will say that the judgment made by the trial court was error. We have reached that point in the past, see, e.g., Metallic Gold Mining Co. v. Watson, supra, and we reach that point here.
We are not here critical of the juror. During the
in camera
hearing, she was completely straightforward. But the most sincere assurances and good faith belief by the juror in her capacity to act impartially cannot compensate for factors which inherently produce prejudice. In this case, it was clear that the juror was sufficiently upset by the defendant’s possible earlier contact with her pregnant daughter that she called his employer to have him reprimanded. Further, the juror had raised the possibility in her mind that it was her daughter’s knife which had been used in the alleged rape. Thus, we are not dealing with an opinion or abstract belief in the defendant’s guilt or innocence.

v.
Buckner,
We adopt the very cogent reasoning of the court in
Delaney v. United States,
II.
At a retrial, an additional problem raised by the defendant is likely to reoccur. The trial court prohibited the introduction of testimony from a psychologist concerning the victim’s possible attitudes toward men and sex and of hypothetical reactions of people with such attitudes.
See Daugaard v. People,
The judgment is reversed and the cause remanded for proceedings not inconsistent with the views expressed herein.
