Social psychology is the scientific study of how people think about, influence, and relate to one another. It examines topics such as how people see themselves and others, what determines decision-making and attraction, the causes of racism and how to reduce it, when and why people help others, what causes aggression and how to reduce it, how persuasion works, and how to increase self-control. Social psychology focuses on the interaction between a person and their social situation, and how situations strongly shape thoughts, attitudes, emotions, and behavior. It also examines how people are both cultural animals and have competing selfish and social impulses, as well as automatic and conscious thought processes that construct our reality.
