Evidence

Reflecting on Allport’s tensions has often proved to be creative, with the field circling back years later to rediscover (to good effect) a relatively ignored strand of Allport’s thought (e.g., the revival of motivated cognition). Discovering what Allport missed has taken longer, which testifies to Allport’s impact. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 136
