This experiment explores cooperation and punishment dynamics among in-group and out-group members from the perspectives of Japanese and American participants. Findings suggest that people tend to punish in-group non-cooperators, highlighting the significance of establishing good partnerships in international studies. The study involved 4 Japanese and 4 American participants selecting individuals to give money to and determining punishment costs for overlooking behavior. Despite some variations, the results indicate a preference for punishing in-group members but with notable differences between the two cultural groups.

Purpose • Examining whether people cooperate more with in-group members than with out-group members. • Examining whether people overlook more in-group members than out-group members to punish non-cooperative behavior.
Task • 4 Japanese and 4 Americans participants. • Each participants choose 1 person from 7 person to give his/her money to, and decide how much money to give. • Each participants choose another person to overlook his/her giving behavior, and decide how much money to pay for punishing the overlooked person.
Results • American participants did not statistically significantly chose more in-group members than out-group ones to give money to, and chose more in-group members than out-group ones to overlook his/her giving behavior. • Japanese participants chose more out-group members than in-group members to give money to, and chose more in-group members than out-group ones to overlook.
Conclusion • General conclusion: People punish in-group non-cooperators. • My conclusion: In order to make it in international study, it is the MOST important to establish good partnership among experimenters.
