stanley milgram conducted a classic experiment on obedience to authority in the 1960’s. when soliciting participants, he advertised it as a study of learning. subsequently, participants served in the role of the "teacher" who sat behind a controller and administered "electric shock" to the "learner" for incorrect responses. throughout the study, participants believed that they had either badly injured, or in some cases, created a fatality. what about this study is considered ethically problematic in contemporary psychology?
