How can counselors be most effective in advising clients who seek help in making vital decisions concerning health, career, marriage or other aspects of their personal lives? Irving Janis offers this practical guide, basing his suggestions mainly on the findings from recent field experiments in health clinics.
Irving L. Janis was a research psychologist at Yale University and a professor emeritus at the University of California, Berkeley most famous for his theory of "groupthink" which described the systematic errors made by groups when taking collective decisions. He retired in 1986.
He also collaborated with Carl Hovland on his studies of attitude change, including the sleeper effect.
