Which of the following is associated with the 'P-O-X' triangle?

The correct answer is Option (2) → Concept of balance

The concept of balance, proposed by Fritz Heider is sometimes described in the form of the ‘P-O-X’ triangle, which represents the relationships between three aspects or components of the attitude. P is the person whose attitude is being studied, O is another person, and X is the topic towards which the attitude is being studied (attitude object). It is also possible that all three are persons. The basic idea is that an attitude changes if there is a state of imbalance between the P-O attitude, O-X attitude, and P-X attitude. This is because imbalance is logically uncomfortable. Therefore, the attitude changes in the direction of balance.
