Was the TED Talk with Philip Zimbardo good?

NO

• The slides had way too much text
• Because he was talking way too fast
• He did not explain the relevant studies thoroughly
• He did not make any pauses so that we can process the information
• He did not let the audience think when he paused questions
• He does not go into detail about the emotional scarring (the reason the experiment stopped)
• He gave too much raw data / unexplained information
• It lacks ecological validity:
• The participants knew they were taking part in an experiment
• The prisoners knew that the prison guards were also participants
• It was a relatively small sample (only a dozen per group)
• Only male participants
• Only from a particular area --› particular cultural background
• Only from a particular age group
• Participants were paid, so they had some incentive to stay
