Abstract:Mock grand juries and individual jurors made indictment decisions for four separate cases, each composed of a single "prosecutor's summary" of the evidence, and 11 additional items of evidence. Juries could either examine all or just a few of the additional items on the first two cases (counterbalanced) so that routine standards of appropriate amounts and rates (information gathering and information processing) of information usage would develop. Groups' relatively greater adherence to these standards was predicted. Jurors were placed under accountability pressures on one of the two last cases. Analysis of amounts and rates of information processed indicated groups' poor information processing. A simulation traces the deficit to constraints due to the groups' slowest members. Also, results showed that groups were relatively more reactive to accountability pressures. However, the effect of initial limits on groups were nonsignificant and thus it could not be demonstrated that groups persisted in routine behavior more than individuals.
