Social network complexity: People with more diversified, complex social networks have been found to be more tolerant of out-groups and more supportive of policies helpful to them. They tend to have more positive out-group experiences, share more interests with people outside their own groups, and learn more about the contributions of out-group members and the problems they face.

Human beings are driven toward consistency and coherence in their perception, thinking, feeling, behavior, and social relationships. This is natural and functional. Conflict intensifies this drive, which can become dysfunctional during prolonged conflicts. However, developing more complex patterns of thinking, feeling, acting, and social organizing can mitigate this, resulting in more constructive responses to conflict.

[Standard social science approaches to analyzing conflict] too often miss the unintended consequences of well-intentioned acts. Dietrich Dorner is a German psychologist who studies leadership and decision making in complex environments. He has suggested that there is more harm done in today's world by well-intentioned people trying to do good, who are unaware of the unintended consequences of their actions, than by people actually trying to cause harm. Remarkably, this may well be true.

Relational balance: Research also shows that people prefer their relationships with others to be aligned and balanced. In other words, we prefer that all our friends be friendly with each other and that they dislike our enemies. Any imbalances between our friends and enemies results in the motivation to change friends to enemies or enemies to friends.
