A Theoretical Explanation for the Intermediate Level of Tension Found in Nonbalanced P-O-X Triads

Empirical evidence has abundantly demonstrated that people report an intermediate level of tension for triadic interpersonal relations of the classical Heiderian P-O-X type, when the P/O link is negative. Low tension is found in balanced triads and high tension in imbalanced ones when the P/O bond is positive. This paper postulates that the opposing forces of balance and of agreement found in all four P-O-X triads in which the P/O bond is negative, in addition to Newcomb's lack of engagement hypothesis, may also account for the intermediate level of tension found in practically all experiments in this area. Subjects were grouped as Hi and Lo Conformists according to the C Scale of the Comrey Personality Scales, and later asked to rate hypothetical triads with a negative P/O bond. The results confirmed the hypotheses that Hi Conformists, who supposedly value agreement with others more than Lo Conformists (or are less bothered by disagreement than the latter), report significantly less tension and less willingness to change P-O-X triads with agreement than those with disagreement, when such triads have a negative P/O bond.
