Philip G. Zimbardo (born March 23, 1933) is an American psychologist, best-known for his Stanford prison experiment and bestselling introductions to psychology.
Zimbardo was born to Sicilian parents, George Zimbardo and Margaret Bisicchia, grew up in New York City, in the South Bronx, and went to Monroe High School with Stanley Milgram. He earned his Bachelor's degree from Brooklyn College, and his Master's degree and Ph.D. from Yale University.
After teaching intensively at New York University, in 1968 he accepted a tenured position as professor of psychology at Stanford University. There he conducted the famed Stanford prison experiment, in which 24 normal college students were randomly assigned to be prisoners or guards in a mock prison located in the basement of the psychology building at Stanford (3 additional college students were selected as alternates, but did not participate in the experiment). The students quickly began acting out their roles, with "guards" becoming sadistic and the "prisoners" showing extreme depression and passivity.
Though planned to last for an entire two weeks, the experiment had to be terminated after only six days when graduate student Christina Maslach, then Zimbardo's girlfriend, watched live video feed of the experiment from his office and insisted the experiment be stopped. (Maslach has since married Zimbardo and is now a psychology professor at UC Berkeley.) The experiment led to theories about the importance of the social situation in individual psychology that are still controversial today.
After the experiment, Zimbardo turned to look for ways he could use psychology to help people and ended up founding The Shyness Clinic in Menlo Park, California, which treats shy behavior in adults and children. Zimbardo's research on shyness also led him to write several bestselling books on the topic.
Zimbardo is also the author of an introductory Psychology textbook, Psychology and Life, which is used in many American undergraduate psychology courses. He also hosted a PBS TV series titled Discovering Psychology which is used in many college telecourses and can be watched at learner.org.
Other subjects he researches are mind control and cultic behavior.
In 2002, Zimbardo appeared in the reality television show The Human Zoo. Participants were observed inside a controlled setting while Zimbardo and a British psychologist analyzed their behavior.
That same year he was named president of the American Psychological Association. Under his direction, the organization developed the website PsychologyMatters.org, a compendium of psychological research that has applications for everyday life.
In November 2003, Zimbardo retired from Stanford, but he still returns each winter to teach "Exploring Human Nature", a sort of "greatest hits" course of his favorite topics.
In 2004, Zimbardo testified in the case of "Chip" Frederick, a guard at Abu Ghraib prison, arguing that Frederick's sentence should be lessened since Zimbardo's prison experiment had shown that few can resist the powerful situational pressures of a prison. The judge apparently disagreed and gave Chip the maximum sentence. Zimbardo is working on a book about the connection between Abu Ghraib and the prison experiments for a popular audience.
In 2005, Zimbardo received the The Dagmar and Václav Havel Foundation Vision 97 Award in Prague.
