Solomon Ash's study
The Solomon Ash study was an experiment done to see how long it took for people to conform. It consisted of a six actors and one subject. The subject had no idea it was a conformity test because they were told it was a visual perception test. The test consisted of a standard line and 3 comparison lines. The group was asked to match the standard line with the comparison line that had the same length. The five actors purposefully matched the wrong lines together to see if the subject would conform and how long would it take till they did conform.
Most subjects conformed because they felt discomfort, awkward, and they weren't playing the game right.
