When interviewing Px some said they conformed because they felt self-concious giving the correct answer and were afraid of disapproval
When answers were written down privately, conformity fell to 12.5% - no normative group pressure
Strength for ISI: study support
Lucas et al. (2006) gave 'easy' and 'hard maths problems
More people conformed to incorrect answers when the maths problems were difficult i.e. situation became ambiguous (unclear)
Px didn't want to be wrong so relied on answers given (not real) from 3 other students
Results are what ISI would predict about conformity
Counterpoint - Lucas et. al.
often unclear whether it is NSI or ISI at work in research studies (or in real life)
Asch (1955) found that conformity is reduced when there is one other dissenting participant
the dissenter may reduce the power of NSI (because they provide social support)
may reduce the power of ISI (because they provide an alternative source of social information)
hard to separate ISI and NSI and both processes probably operate together in most real-world conformity
A limitation of NSI is it does not predict conformity in every case
nAffiliators: people who are greatly concerned with being liked by others/have a strong need for 'affiliation' (i.e. they want to relate to other people)
McGhee and Teevan (1967) found that students who were nAffiliators were more likely to conform
NSI underlies conformity for some people more than it does for others
there are individual differences in conformity that cannot be fully explained by one general theory of situational pressures
