Asch [1952 , 1956] changed the procedure to investigate which situational factors influenced the level of conformity
group size : the bigger the majority group , the more people conformed | with one other person conformity was 3 % , with two people it went up to 13%
lack of group anonymity or the presence of an ally :
Asch 1956 found that even a presence of just one confederate that goes against the majority choice can reduce conformity as much as 80%
difficulty of task
harder the task , the higher levels of conformity [ when we are more uncertain , we look to others for confirmation -> informational social influence ]
answer in private - asch 1952
when pps are allowed to answer in private , conformity decreases [ this is due to less group pressure and normative influence is less powerful ]
