Evaluation?
DC? Study? NSI?
Didn’t tell pp the aim of study to eliminate demand characteristics.
Lab experiment- artificial situation- lacks mundane realism - doesn’t reflect actual behaviour.
Little about majority influence where people conform to totally wrong answers.
May involve NSI as well as ISI- desire to be accepted rather than be correct.

Aim? Procedure? Findings?
A- investigate the degree to which individuals would conform to a majority who gave obviously wrong answers.
P- 1) 123 american male student volunteers told they were in a visual perception study.
2) groups between 7 and 9 here there were confederates.
3) which comparison line A B or C was the same as a stimulus line on 18 different trials. 12 were critical value where the confederates gave the same wrong answer. naive pp gave answer second to last or last.
4) control group of 36 pp were tested individually on 20 trails.

12 critical trails- 32% conformity rate.
75% conformed to at least one answer.

post experiment interviews showed people confirmed due to doubt of accuracy, avoid ridicule distortion.
