Aim: Asch wanted to know whether people could be influenced by other peoples opinions to gie an answer they know to be wrong. In this way it would be possible to see if people were conforming.
Method: Participants were shown sets of four lines. For each set, participant had to say whether line A, B or C was the same length as the test line. When tested alone, participants rarely made a mistake (the error rate was less that 1%). However, participants also had to give their answers as part of a group. the rest of the group was instructed to give incorrect answers for some of the tests.
Results: on 32% of the trials where the rest of the group gave the wrong answer, the participant gave the same wrong answer as the rest of the group, rather than the obviously correct answer. In fact 74% of the participants gave at least one wrong answer.
Conclusion: The only reason for this 32% error rate was hearing the incorrect answers previously given. Those who gave incorrect answers told Asch they knew their answers were wrong but didnt want to go against the rest of the group. this clearly demonstrates normal social influence.
