96 college students, a group of 4, participated in the evaluation of police behavior decision-making experiment. The study used a 2 × 2 × 2 (time × purpose × behavioral) factorial design to analyze how time, purpose, and behavioral characteristics influence Chinese people’s decision-making behavior. The results show that the decision-making groups are better than the individual members in the behavioral memory, but the decision-making criteria of the groups are more risky than the individuals. The temporal, objective and behavioral characteristics influence the performance of group decision-making. The conclusions support the “complementarity hypothesis” and K. R. Murphy’s explanation of the interaction between time and purpose
