This article presents an interview with Philip Zimbardo, emeritus professor of psychology at Stanford University, who is internationally recognized as the voice and face of contemporary American psychology. He earned his PhD in social psychology from Yale University in 1959 and has since received seven honorary doctorates for his contributions to psychology and society. The author of more than 300 publications and 50 books, Zimbardo's research spans 20 topics, including shyness, evil, teaching, persuasion, hypnosis, dissonance, time perspective, and heroism. He is best known for his landmark study, the Stanford Prison Experiment; his widely seen TV series, "Discovering Psychology"; and his best-selling textbook, "Psychology and Life." He is past president of the Western Psychological Association (WPA) and the American Psychological Association (APA), and has received distinguished teaching awards from WPA, APA, Stanford University, Phi Beta Kappa, and the Society for the Teaching of Psychology. His aim to "give psychology away" is evident in all he does. In this interview, Zimbardo discusses how he began his career in teaching psychology, and shares his views on teaching and psychology.
