Subjects completed 18 trials. On the first two trials, both the subject and the actors gave the obvious, correct answer. On the third trial, the actors would all give the same wrong answer. This wrong-responding recurred on 11 of the remaining 15 trials. It was subjects' behavior on these 12 "critical trials" that formed the aim of the study: to test how many subjects would change their answer to conform to those of the 7 actors, despite it being wrong. Subjects were interviewed after the study including being debriefed about the true purpose of the study. These post-test interviews shed valuable light on the study: both because they revealed subjects often were "just going along" and because they revealed considerable individual differences to Asch. Additional trials with slightly altered conditions were also run, including having a single actor also give the correct answer.
