Oxytocin motivates non-cooperation in intergroup conflict to protect vulnerable in-group members.

Intergroup conflict is often driven by an individual's motivation to protect oneself and fellow group members against the threat of out-group aggression, including the tendency to pre-empt out-group threat through a competitive approach. Here we link such defense-motivated competition to oxytoc...
