Explanation: Solomon Asch carried out series of experiments meant to measure how social pressure determines conformity. The task was to judge line sizes, to choose the same line in a pair of cards. The answer was obvious as the other lines were not similar to the correct line.
Participants were mixed with non-participants planted by Asch but the participant is unaware of this and made to answer after them. The non-participants give incorrect answers and if the real participant also gives a wrong answer, it is because of the need to conform.
