Outline of Final Research Achievements

What kind of psychological process works when people in groups fight against other groups, like war? It is sometime claimed that human beings has some "instinct" to attack against other group, but current study showed that people rarely attack other groups without any reason. On the other hand, when the opponent's ability to attack oneself is stronger than the ability to attack opponents, it is also showed the possibility that people has an inclination to attack especially toward other group members.
