Who conducted an experiment on conformity in which people were asked to judge the length of lines?

The experiment on conformity was conducted by psychologist Solomon Asch in the 1950s. In his study, participants were asked to judge the lengths of lines while being influenced by a group of confederates who intentionally provided incorrect answers. Asch's findings revealed that individuals often conformed to the group's wrong judgments, highlighting the power of social pressure on individual decision-making.
