Biases in favor of culturally prevalent social ingroups are ubiquitous, but random assignment to arbitrary experimentally created groups is also sufficient create ingroup biases (i.e., the minimal group effect; MGE). The extent which bias arises from specific contexts versus more general psychological tendencies remains unclear. This registered report focuses on three questions. First, how MGE? Second, do critical cultural and individual factors moderate its strength? Third, does MGE meaningfully relate salient real-world biases? We compare a family member (first cousin) national member. propose recruit sample > 200 participants each 50 nations examine these questions advance our understanding foundations prevalence bias.
