Final answer:
Compliance in Milgram's experiment dropped when the teacher had to put the learner's hand on and when the humanity of the person being shocked was increased. Lower levels of compliance were also observed when the authority of the experimenter decreased.
Step-by-step explanation:
In Milgram's experiment, compliance, or doing what the experimenter asked, dropped when the teacher had to put the learner's hand on. When the teachers' and learners' hands were touching, the highest shock rate dropped to 30% (Milgram, 1965). This variation shows that when the humanity of the person being shocked was increased, obedience decreased. Lower levels of compliance were seen when the authority of the experimenter decreased.
