Book excerpt: The Second Edition succeeds in showing that social psychology has a potent contribution to make to understanding human behavior. Drawing on landmark experiments, real-life cases, and his own valuable insights, Brown analyzes a wide range of subjects including obedience and rebellion, altruism, group decision processes, the psycholegal questions of eyewitness testimony, jury size and decision rule, the psychosexual question of androgyny, the sources of ethnic conflict, and much more.
