Does ingroup love lead to outgroup hate? NO! I often try to explain to people that identifying with ingroups does not necessarily lead to outgroup discrimination. I call this the "Myth of tribalism". A new paper provides strong and robust evidence for a positive relationship between ingroup and outgroup prosociality.! Across six datasets that span multiple domains of prosociality and group distinctions with 743,402 individuals in 121 societies, finds that people who are prosocial toward the ingroup also tend to be prosocial toward the outgroup. "The results offer an optimistic message for prosociality across group boundaries. When people are not made to choose between the ingroup and outgroup, they are generally prosocial toward both." Here is the new research: pnas.org/doi/10.1073/pnas.25… Here is an article I co-authored for The Atlantic on the Myth of Tribalism in 2022: theatlantic.com/ideas/archiv…
