Effects of voir dire variations in capital trials: A replication and extension

With a sample of 18 capital cases tried in Kentucky, South Carolina, and California, we attempted to replicate an earlier study which showed that significantly more defense challenges for cause were granted under conditions of sequestered, individual voir dire than when voir dire was conducted under less enhanced conditions. In the current sample, sequestered, individual voir dire again resulted in more defense removals for cause than obtained with less extensive voir dire. We present data on the defense removals for cause partitioned into five categories according to the reason for the challenge and analyze the effects of jury selection consultants on the various indices of voir dire as well as final sentence.     

Effects of prior juror experience on jury sentencing

The effect of prior juror service on jury sentencing was investigated in an archival study of 143 criminal trials resulting in convictions. Trials took place over two calendar years in a state circuit court requiring jurors to serve 30-day terms. Jurors sentenced defendants in each case according to a set of guidelines determined by trial judges. The severity of the sentences imposed by jurors was rated by 101 subjects on a scale of 1 (least severe) to 100 (most severe). The results indicated that the more experienced juries gave significantly more severe sentences than did the less experienced juries. This finding was unchanged when civil court experience was considered in addition to criminal court experience. Possible interpretations of these results are discussed.
