Jury Selection


Voir Dire

        Jury selection begins with venire, the drawing of a panel of prospective jurors. This panel is usually chosen from people on the voter's registration list, or from other sources, depending on whether it is a state or federal court. The number of people on the panel varies. Once the panel of jurors has been drawn, the next step is to select a panel of 6-12 jurors for the case, a process known as voir dire. The purpose of voir dire is to select an unbiased and representative panel. During this stage, prospective jurors are questioned by the attorneys and the judge to eliminate anyone that is biased, related to the case, or prejudiced. Jurors that are excused for any of these reasons are excluded from service for cause. In addition, attorneys are given a set number of peremptory challenges, which allow attorneys to exclude without reason a particular number of prospective jurors from the eventual jury.

Scientific Jury Selection

        Jury selection consultants aid attorneys (usually defense attorneys) by using empirically based procedures to detect bias during jury selection. Consultants also aid attorneys with the preparation of witnesses. Voir dire has three main goals: to elicit information from jurors, to establish a relationship between the attorneys and the jurors, and to educate the jury about the defense's and prosecution's case. . Attorneys must develop the theory of their case thoroughly before jury selection begins, and the jury consultant should know the case theory thoroughly. With this knowledge, consultants administer community surveys and focus groups to ascertain how individual characteristics relate to reactions toward the case. Jury selection consultants also conduct post-trial interviews with people who served on juries, and with people who were excused from service. This enables consultants to determine how juror characteristics may relate to juror decision making. Findings from these studies enable consultants to determine which prospective jurors should be eliminated from serving on subsequent cases.

Scientific Jury Selection vs. Traditional Jury Selection

        Research findings seem to support the claim that scientific jury selection works better than traditional methods for cases in which juror attitudes are particularly important, such as in capital cases. In one study, researchers examined the outcomes of 35 capital trials (Nietzel & Dillehay, 1986). They found that juries recommended the death sentence at a rate of 61.1% in the 17 cases in which no jury consultant was used, and in contrast, juries recommended the death sentence at a rate of 33.3% in the 18 cases in which a jury consultant was used. Scientific jury selection, however, is not as effective when juror attitude variables are weak. One study, for example, found that there are no differences in outcome between conventional and scientific jury selection, except for when there is a definite relationship between personality or demographic variables and jurors' votes (Horowitz, 1980). At any rate, jury panels can never be truly representative or unbiased. Not everyone is called to participate in the process; thus, not all segments of the population are represented on juries. Attorneys, moreover, seek out jurors that will benefit their side of the case. If one attorney is more motivated and skilled than the other in selecting a jury, then the outcome may not be just.
