Jenness found that participants conformed to the group answer when they were in an ambiguous situation (the answer was not clear)
This supports the idea that people may conform when they do not know the answer in order to be right, as suggested by Informational social influence
strength -
Asch’s found that in an unambiguous line task, some participants conformed as they did not want to be rejected from the group.
This supports the idea that some conformity is due to the desire to not be rejected by the group for disagreeing with them, as normative influence suggests.
weakness -
Some people are more concerned with being liked than others are and these people are more likely to conform due to NSI.
This suggests that there are individual differences in conformity and one general theory can not explain everyone's behaviour.
