When Asch interviewed his participants, some said that they conformed because they felt self-conscious giving the correct answer and they were afraid of disapproval. When participants wrote their answers down, instead of saying them out loud, conformity fell to 12.5%. This is because giving answers privately meant there was no normative group pressure. Also in Asch's group size variation conformity rose significantly when there were three confederates due to the group pressure. This shows that at least some conformity is due to a desire not be rejected by the group for disagreeing with them.
