conclusion

  • Guards and prisoners adapted to social roles quickly
  • Zimbardo claims this shows that our social role can influence our behaviour- seemingly well-balanced ment became umpleasant and aggressive n the role of guard.

Evaluation

  • This was a controlled observation, so there was good control of variables. However, because it was an artificial experiment the results can't really be generalised to real- life situations.
  • Ethical issues- some participants found the experience very distressing
  • Observer bias problem- he ran prison himself, & later admitted that he bacame too personally involved.
  • The conclusion he reached doesn't explain why only some of the participants acted according to their assighned roles ( 1/3 behave brutally)
  • 1/3- keen on applying the rules fairly
  • rest actively tried to help and support the prisoners , sympathising with them, offering them cigarettes and reinstating privileges (Zimbardo 2007)
