Asch experiment: The likelihood of conformity increases when faced with unanimous group opinion (32%). If even one person dissents, however, conformity drops to 8%. With only one other person in the room, there is 2.8% conformity; 12.8% conformity with two, and about 30% with four people (no increase with groups over four). (Ornstein, Robert. Multimind. p 92-96.
