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.
