In this project, we conceptually replicated Gershon and Fridman (2022):
Gershon, R., & Fridman, A. (2022). Individuals prefer to harm their own group rather than help an opposing group. Proceedings of the National Academy of Sciences, 119(49), e2215633119. https://doi.org/10.1073/pnas.2215633119
The project is now published as:
Kasper, M., Böhm, R., Xiao, Q., & Columbus, S. (2023). Individuals benefit individual out-group members rather than harm in-group members. Proceedings of the National Academy of Sciences, 120(12), e2301107120. https://doi.org/10.1073/pnas.2301107120
