Kerman proposed three types of conformity in 1958.
Compliance - changing behaviour publicly but privately harbouring a different view.
Internalisation - Adopting a view both publicly and privately.
Identification - Conforming publicly and privately to impress a group WHILE you are with that group.
Normative Social Influence - Desire to be liked (links to compliance and identification).
Informational Social Influence - Desire to be right (links to internalisation).
Difficulties between compliance and internalisation happen as someone may publicly band privately disagree with something but then change their mind when they are alone.
Linkenbach and Perkins found that adolescents exposed to the message that the majority of their peers didn’t smoke, were less likely to smoke (NSI).
Schultz et al found that hotel guests who were told that 75% guests reused their towels reduced their towel usage by 25%.
Jenness 1932
Filled a glass bottle full of jelly beans and asked 101 students to guess how many were in there.
After their original guess they were divided into groups of three to discuss.
Once they had finished they were asked to guess again.
Jenner’s found nearly all participants changed their original answer.
Individual differences play a role in NSI. For example there are some people who care more about being liked than others called nAffiliators.
