Persistent anger stems from rumination, not pent-up aggressive impulses

Evidence

Actually, anger arousal dissipates over time but is easily regenerated on later occasions if the person ruminates about anger-provoking incidents. Indeed, people can work themselves into a rage long after their anger has subsided. Persisting anger has more to do with ruminative self-arousal than with an undischarged reservoir of aggressive impulses pressing for release. — Albert Bandura, Moral Disengagement, 832
