P-O-X triangle of balance theory is given by :

Human beings have a need to interact with and relate to others and to explain their own as well as others’ behaviour. Because of these social interactions, people form attitudes about other individuals and also about different issues in life. These attitudes have an evaluative feature, are accompanied by an emotional component and a tendency to act in a particular way with respect to the attitude object. Negative attitudes towards others, called prejudices may be based on stereotypes. These stereotypes often assumes that all members of a specific group possess certain undesirable characteristics which leads to the formation of negative attitudes towards members of that group. Prejudice has many other sources and often creates conflict within a society. Awareness about these sources would be the one of the steps in handling these prejudices.
