<P> Subjects completed 18 trials . On the first two trials, both the subject and the confederates gave the obvious, correct answer . On the third trial, the confederates 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 confederates, 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 . </P> <P> Solomon Asch's experiment also had a condition in which participants were tested alone with only the experimenter in the room . In total, there were 50 subjects in the experimental condition and 37 in the control condition . </P> <P> In the control group, with no pressure to conform to confederates, the error rate on the critical stimuli was less than 1% . </P> <P> In the confederate condition also, the majority of participants' responses remained correct (63.2 per cent), but a sizable minority of responses conformed to the confederate (incorrect) answer (36.8 percent). The responses revealed strong individual differences: Only 5 percent of participants were always swayed by the crowd . 25 percent of the sample consistently defied majority opinion, with the rest conforming on some trials . An examination of all critical trials in the experimental group revealed that one - third of all responses were incorrect . These incorrect responses often matched the incorrect response of the majority group (i.e., confederates). Overall, 75% of participants gave at least one incorrect answer out of the 12 critical trials . </P>
