Asch Conformity Experiment

A 3D re-creation of Solomon Asch's classic line-judgment study: a subject sits at the end of a row of confederates who are all shown the same board — one standard line and three comparison lines, A, B and C — and asked which comparison matches the standard. On critical trials every confederate unanimously names the wrong line before the subject answers. This simulator drives the subject's response with a logistic conformity model fitted to Asch's published conformity rates, so you can watch the classic findings emerge live: conformity rising sharply with group size and then plateauing, and a single dissenting "true partner" collapsing it by roughly six-fold.
