Sometime during the 1950’s, Solomon Asch performed a psychological experiment in which participants were brought into a room and told that their vision was going to be tested. One group of participants were simply shown an image of a line, and asked to compare the length of the line to three other lines. Specifically, they were asked, “Of these three lines, which one is the same length?” Only 1 in 35 participants answered incorrectly.
Another group of participants sat with a number of other “participants,” and each participant in the room was asked the same question, in turn. The other participants in the room were all collaborators with the experimenter, and they each gave the same incorrect answer to the question. The real participants were always the last to answer the question, and 75% of the participants gave the same incorrect answer as the rest of the collaborators. These results are interesting enough that this experiment has been performed by psychology undergraduate students hundreds of times, and often with the same results. Even I’ve participated in this experiment as an undergrad, because, face it, it’s fun to watch obvious social conformity at work. Continue reading
