In a series of studies social psychologists examined group forgiveness and found that individuals are astute perceivers of political process. For an apology to be sincere, the process must show that the offenders are in agreement about the apology and that the person(s) saying sorry for the group represents the whole group.
Emotions are powerful motivators of human behavior and attitudes. Emotions also play an important role in guiding policy support in conflict and other political contexts. Researchers at Tel Aviv University and the Interdisciplinary Center in Herzliya have studied the interaction between emotion and political ideology, showing that the motivating power of emotions is not the same for those on different ends of the ideological spectrum. Their research is published in Personality and Social Psychology Bulletin.
