Milgram’s behavioural study of obedience (1963)

Overview of Milgram’s Study

  • Stanley Milgram (1963) conducted a behavioural study of obedience.
  • The research aimed to examine the extent to which individuals would obey an authority figure, even when instructions conflicted with personal morals.
  • The study was held in response to the atrocities committed during the Second World War, aiming to understand how such obedience could occur.

Design and Methodology

  • The study was a controlled observation with the researcher acting as a ‘stooge’ who provided the orders.
  • The volunteers were led to believe that they were participating in a learning experiment involving the effect of punishment in learning.
  • Each participant played the role of a ‘teacher’ who had to administer electric shocks to a ‘learner’ (the stooge) every time they answered a question incorrectly.
  • The shock levels ranged from 15 volts (mild) to 450 volts (deadly), increasing with each wrong answer.

Key Findings

  • 65% of participants continued to the maximum voltage of 450 volts, and all participants delivered shocks of at least 300 volts.
  • Participants exhibited signs of extreme stress and tension, but continued to follow orders when reassured by the experimenter.

Ethical Issues

  • Significant ethical criticisms were levelled at Milgram’s study due to the psychological harm caused to participants.
  • Participants were deceived about the true nature of the study and were not immediately debriefed after participation.
  • The study highlighted issues with informed consent, right to withdraw, and protection from harm in psychological research.

Importance and Impact

  • Milgram’s findings have had a profound impact on understanding of obedience to authority in social psychology.
  • They suggest that under certain circumstances, individuals may carry out harmful acts when instructed by an authority figure.
  • The study has contributed to research design ethics, prompting further consideration and discussion of the welfare of participants in psychological studies.

Validity and Reliability

  • There are concerns about the ecological validity of the study, as it was a controlled observation in an artificial setting.
  • The presence of situational variables, such as the location being a prestigious Yale university, might have influenced participants’ behaviour.
  • Conversely, the study shows high internal validity, as it was able to manipulate and control for various factors.
  • The experiment has been replicated with similar results, demonstrating its reliability. However, ethical restrictions now limit the degree of replication of such study.
