TLDR
Results showed that oxytocin drives a “tend and defend” response in that it promoted in-group trust and cooperation, and defensive, but not offensive, aggression toward competing out-groups, so there may be a neurobiological basis for intergroup conflict in humans.Abstract:
Humans regulate intergroup conflict through parochial altruism; they self-sacrifice to contribute to in-group welfare and to aggress against competing out-groups. Parochial altruism has distinct survival functions, and the brain may have evolved to sustain and promote in-group cohesion and effectiveness and to ward off threatening out-groups. Here, we have linked oxytocin, a neuropeptide produced in the hypothalamus, to the regulation of intergroup conflict. In three experiments using double-blind placebo-controlled designs, male participants self-administered oxytocin or placebo and made decisions with financial consequences to themselves, their in-group, and a competing out-group. Results showed that oxytocin drives a "tend and defend" response in that it promoted in-group trust and cooperation, and defensive, but not offensive, aggression toward competing out-groups.read more

Oxytocin and vasopressin in the human brain: social neuropeptides for translational medicine
TL;DR: OXT and AVP are emerging as targets for novel treatment approaches — particularly in synergistic combination with psychotherapy — for mental disorders characterized by social dysfunction, such as autism, social anxiety disorder, borderline personality disorder and schizophrenia.

Social effects of oxytocin in humans: context and person matter.
TL;DR: It is proposed that this literature can be informed by an interactionist approach in which the effects of oxytocin are constrained by features of situations and/or individuals.

Oxytocin increases trust in humans
TL;DR: It is shown that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions.
