Final answer:
Today, ethical guidelines would likely prohibit the replication of Milgram's study in its original form. Modern ethics require protection against psychological harm and informed consent, but adaptations of the study maintain its exploration of obedience. Additionally, samples in contemporary replications are more culturally diverse.
Step-by-step explanation:
If psychologists wanted to repeat Milgram's study on obedience to authority today, it is likely that ethical guidelines would prohibit the study in its original form. Modern ethical standards demand the protection of participants from psychological harm, including distress and trauma, which were significant factors in Milgram's original experiment. Additionally, informed consent and debriefing procedures have been strengthened since the 1960s to ensure that participants are fully aware of the nature of the research and its potential impacts.
Furthermore, contemporary replications of the study, such as those by Burger (2009) and Doliński et al. (2017), have adapted the methodology to adhere to current ethical guidelines while still exploring the core research question of obedience to authority. These studies indicate that the levels of obedience observed in Milgram's original work are still notable, though the experimental conditions have changed to be more ethical.
The diversity of participants in replication studies has also changed, often resulting in a more culturally diverse sample compared to Milgram's initial research group. This shift in participant demographics could potentially affect the generalizability and interpretation of the results, as cultural factors may influence the behavior of individuals in obedience scenarios.
