Administered a resource management task to 86 US and 97 Dutch undergraduates. Ss were divided into groups of 6 and instructed to harvest points from a regenerating resource pool. Their objective was to maximize individual harvests while maintaining the resource pool. The factorial design crossed 3 levels of resource use (overuse, underuse, and optimal use) with 2 levels of variance of others' purported harvests (low and high). Both variables were manipulated through false feedback to Ss regarding the pool size and the other Ss' harvests. The primary dependent measures were Ss' individual harvests and whether Ss voted for or against elimination of free access to the resource in favor of electing a leader who would make harvest decisions for the group. Results indicate that harvest size increased over time only in the under- and optimal-use conditions. As predicted, overuse Ss voted to give up free access to the resource and to elect a leader more frequently than Ss in the other conditions. Differences between American and Dutch Ss were found only for the variance manipulation
