Humans are social creatures; we both influence others and are influenced by them. Social psychology is the study of group and population behaviour, as well as how individuals function within them. At its broadest, it includes preferences, perceptions, choices, and communication from clusters of individuals from the smallest groups (e.g. couples, families, classrooms) to the largest populations (e.g. cities, countries, ethnicities). It is perhaps the most directly-linked to government and public policy, both locally and internationally, of any psychological discipline of the past 30 years. It is very closely tied with other disciplines in the field, particularly individual differences and decision-making.
