Solomon Asch (1951) investigated the extent to which social pressure from a majority group could affect a person's likeliness to conform.
Asch conducted a classic experiment in Social Psychology where participants were asked to match the length of lines on cards.
The experiment involved confederates giving the incorrect answer to see if the real participant would conform to the majority view.
On average, about onethird of participants (32%) conformed to the majority view, with about 74% conforming at least once.
Participants conformed due to NSI (wanting to fit in with the group) and ISI (believing the group is better informed).
The presence of an ally who goes against the majority choice can greatly reduce conformity.
The difficulty of the task increases conformity, as people are more likely to look to others for confirmation when they are uncertain.
Conformity decreases when participants are allowed to answer in private, as there are fewer group pressures and normative influence.
Conformity differs from obedience in that conformity involves adjusting one's behaviour or beliefs to align with the norms of a group, while obedience involves following the orders or commands of an authority figure.
