According to the psychologist Philip Zimbardoconformity is...
"a tendency for people to adopt the behaviour, attitudes and values of othermembers of a reference group."
This can occur without our knowledge.
Psychologists believe that we are all subject to the forces of social influence, whether or notwelikeit! Many of our everydaybehaviours and decisions are the result of the pressure to conform to the opinions and behaviours of other people.
Social Influence is the change in behaviour that one person causes in another intentionally or unintentionally.
