Individuals who strongly identify with all humanity feel close to people all over the world, care for them, and perceive them as an in-group. The research shows that identification with all humanity (IWAH) is connected to human rights orientation and desire for global knowledge (McFarland, Brown, Webb, 2012). However, does such broad identification appears in different countries and cultures and are these relationships universal? To explore these issues we conducted studies in Poland (N = 311), Chile (N = 231), Mexico (N = 183) and the US (N = 313). The results showed the similar pattern of results in all four counties: IWAH was positively associated with willingness to help people from other countries (e.g. organizing a petition against slave work for cloth companies), interest and concern for global issues (desire for global knowledge, concern for global problems and choosing articles about solving them) and protection of human rights. The research proved that human identity appears in different countries and cultures and showed its universal role ininterest and concern for global issues, protection of human rights and prosocial activities toward people from different countries and cultures, however some cultural differences were also noted.
