One of the most ethically controversial experiments in the history of social science. (1960s) Participants were placed as the teacher in the situation and were told to read the pairs to the learner. After they were read once, the teacher then read them again and if the learner failed to answer correctly, he was delivered a shock. The more answers the learner got wrong, the higher voltage the shock. The study was to see how far participants were willing to go. Even after hearing the learner say things like ouch, get me out of here, I told you I have heart problems.
