Social psychology examines how individuals are influenced by others and their social situation. Key topics covered include attribution theory, which explores how we explain our own and others' behavior; conformity and obedience, in which people often go against their own beliefs under social pressure; and prejudice, which forms from a combination of beliefs, emotions, and actions towards social groups. Overall, social psychology demonstrates that individuals are strongly impacted by social and situational factors rather than only personal disposition.
