Philip George Zimbardo was an American psychologist and a professor at Stanford University. He was an internationally known educator, researcher, author and media personality in psychology who authored more than 500 articles, chapters, textbooks, and trade books covering a wide range of topics, including time perspective, cognitive dissonance, the psychology of evil, persuasion, cults, deindividuation, shyness, and heroism. He became known for his 1971 Stanford prison experiment, which was later criticized for its use of methods which allowed Zimbardo himself and whatever biases he may have had to influence the results. He authored various widely used, introductory psychology textbooks for college students, and other notable works, including Shyness, The Lucifer Effect, and The Time Paradox.
