Asch Conformity Experiment Simulator

Interactive Asch line-judgment conformity experiment: watch a subject face a unanimous group giving an obviously wrong answer, tune the number of confederates, and compare the emerging error rate against Solomon Asch's 1951 published data.

This simulator reconstructs Solomon Asch's classic 1951 line-judgment experiment: a lone subject, answering after a unanimous group of confederates who deliberately call out the wrong comparison line, must decide whether to trust their own eyes or go along with the crowd. Each trial draws a card with a reference line and three comparison lines, animates the confederates announcing their (wrong) answer one by one, then samples the subject's response from Asch's own published conformity curve for the chosen group size. A running chart compares this simulation's live error rate against that published data, showing how conformity pressure climbs sharply from one to three unanimous opponents and then plateaus — a real, measured psychological effect, not an assumption.

⚙ Under the hood

Conformity rate increases as more confederates give an obviously wrong answer, mirroring Asch's original findings.
