"How defence rhetoric escalates untergroup conflict" spkl.io/63325AbcXh Luuk Snijder, Jorg Gross, & @dedreu.bsky.social @cp-iscience.bsky.social

Leaders often justify aggression with false claims of self-defense. The general public, and LLMs, easily fall for false defense rhetoric. Framing attack as defense makes followers fight harder and win more often. False signaling benefits attacking leaders while harming everyone else.

Did cooperation evolve because of conflict? Or is conflict an (avoidable) ‘by-product’ of evolved capacities to cooperate. I think the latter—> journals.sagepub.com/doi/pdf/10.1...

🚨🚨New paper out at with Jörg Gross & @dedreu.bsky.social: The nasty neighbor effect in humans. Across 51 societies and >14,000 participants, and against pre-registered predictions, we find that humans compete more within than between groups: www.science.org/doi/10.1126/...

Humans not only cooperate but also compete more with in-group members than with out-group members and strangers.
