Research support for NSI: Asch held an experiment to see if people would conform to incorrect answers. When 123 male american undergraduate participants were shown a line then 3 comparison lines and asked which closely matched, they conformed with the 6-8 confederates in their groups and gave the wrong answer 36.8% of the time. When asked why they said they felt self-conscious giving the correct answer and didn’t want the group to disapprove. When he repeated the experiment but asked participants to write down the answers, conformity dropped to 12.5%.
