A study investigated the effects of order verdict consideration and decision rule on jury verdicts. After reading the summary of an actual trial, 240 mock jurors drawn from undergraduate communications classes were randomly assigned to six-member juries. Jury assignments were made under two verdict orders (ascending and descending order of potential penalty harshness) and two decision rule conditions (unanimity and quorum). The juries then deliberated until their assigned decision rules were achieved. Results indicated that ascending order juries deliberate longer, descending order juries hand down harsher verdicts, and unanimous juries spend more time in deliberation than quorum juries.
