Solomon Asch (1907–1996)

A Polish-born American social psychologist, Solomon Asch became world-renowned for his Conformity Experiments, which powerfully demonstrated how group pressure can influence an individual's judgment.

In his famous Line Judgment Experiment of 1951, Asch asked participants to identify which comparison line matched a standard line in length — a task with an obvious correct answer. However, when confederates deliberately chose the wrong answer, approximately 75% of real participants conformed to the incorrect majority at least once. On average, conformity occurred in about 37% of all trials.

Asch identified two key reasons for conformity: Informational Influence, which stems from the belief that the majority possesses more accurate information, and Normative Influence, which arises from the desire to avoid rejection by the group. His research laid the groundwork for subsequent studies on groupthink, social influence, and the importance of minority opinion.

*Mindy's note: It can feel very uncomfortable to stand alone against a group — Asch's work reminds us that this struggle is deeply human, and that awareness of social pressure is the first step toward independent thinking.*

💡 Real-Life Example

Even when an answer is obviously wrong, if the majority insists it is correct, a significant number of people will abandon their own judgment and conform to the group.
