Most of the articles were originally published in psychological journals or law reviews. Accompanying the articles on each topic are introductions and summaries prepared by the volume's editors. The papers on jury selection consider the procedures used in the Harrisburg Seven trial in 1972 and the effectiveness and the ethical appropriateness of the use of scientific jury selection. The analyses of juror bias examine differences between authoritarian and nonauthoritarian individuals, the role of nonrational factors in jury decisionmaking, and discrepancies between the bias of individual jurors and the fairness of jury verdicts. The papers on jury competence in complex civil cases focus on the impacts of the timing and wording of judges' instructions and suggest ways for remedying problems in current procedures. The analyses of jury size and the decision rule discuss research designs for studying jury size, existing literature on jury size, and outcome and process effects of shifting a majority decision rule.
