Study: People expect others to mirror their own selfishness, generosity

A person's own behavior is the primary driver of how they treat others during brief, zero-sum-game competitions, researchers report. Generous people tend to reward generous behavior and selfish individuals often punish generosity and reward selfishness -- even when it costs them personally.
