Asch- Normative social influence study: He designed an experiment to see whether people would conform to a majority's incorrect answer when it was obvious it was wrong. He used a lab experiment using an independent group design. In groups of 6 or more, participants judged line lengths by saying out loud which comparison line (1, 2 or 3) matched the standard line. The groups only contained one rel participant- the rest were confederates (helpers of the experiment who acted like real participants). The real participant always went last or second from last so that they heard the others answers before giving theirs. There were 18 trials. on 12 of these trials, all confederates gave the wrong answer (these were called critical trials). In of the trials the confederates gave the incorrect answer (control trials).
Results- In the control trials, participants gave the wrong answer less than 1% of the time. In the critical trials, [participants conformed to the majority (by giving the same wrong answer) 37% of the time. 75% conformed at least once. Afterwards, some participants said they didn't really believe their answers, but didn't want to look different (compliance).
