The Asch Conformity Experiment, conducted by psychologist Solomon Asch in the 1950s, aimed to investigate the extent to which social pressure from a majority group could influence an individual’s judgment. Participants were asked to match the length of a line to three comparison lines, while confederates (actors) intentionally gave incorrect answers. The results showed that many participants conformed to the group's incorrect responses, even when the correct answer was obvious. This demonstrated the powerful effect of group influence on individual decision-making, highlighting the conflict between personal beliefs and social conformity.
