Internalisation is a deep type of conformity where we take on the majority view because we accept it as correct, leading to far-reaching and permanent changes in behaviour even when absent from the group.
Identification is a moderate type of conformity where we act in the same way as the group because we value it and want to be a part of it, but we don’t agree with it privately.
Informational social influence is an explanation of conformity that says we agree with the opinion of the majority as we believe it is correct, as we want to be correct.
