Introduction Social psychology tries to examine how individuals think, interact or influence each other. Also, social psychology explores people’s ability to think critically. Social psychology brings about reality. Moreover, it exposes people’s social intuitions as either perilous or safe. It is necessary to note that social influences are very significant in shaping people’s behavior. Additionally, attitudes are also crucial in shaping people’s behavior. It is also necessary to note that social behaviour can be biological. Social psychology’s principles are usable in numerous disciplines. Moreover, they are applicable in real life situations. This paper with examines and identify social psychology’s principles as used in various circumstances (Cloninger, 2005). Video 1: Meryl Streep: The Devil Wears Prada Behavior and Attitude Attitude and behaviour refer to the kind of reaction one has for something. This reaction can be favorable or unfavorable.
