Jurors' knowledge of battered women

An increasing number of psychologists with expertise in the area of battered women are participating in the legal system as expert witnesses and occasionally testify on behalf of a battered woman who has injured or killed her partner. Testimony about the battered woman syndrome has been offered to help the jury understand why the defendant reasonably perceived that she was in danger of harm. One of the requirements of expert testimony is that it be beyond the common understanding of the jury. Many commentators assume that jurors are uninformed or misinformed about battered women and, thus, that expert testimony is necessary to educate them. This study evaluated what jurors know about violent relationships. Approximately 300 jurors read scenarios about spousal violence and answered a questionnaire dealing with circumstances surrounding such abuse. Results suggest that on certain dimensions of spousal violence, jurors are aware of empirical research findings. On other dimensions, jurors are less well-informed and could potentially benefit from the testimony of an expert.
