Balance,positivity, and agreement in the Jordan Paradigm: A defense of balance theory

It was argued that Heider's p?o?x triad can best be conceptualized according to a three- factor analysis of variance model in which the p?o, p?x, and o?x bands are all factors. From this perspective the balance effect is the triple interaction, the positivity effect a main effect for the p?o factor, and the agreement effect a p?x by o?x interaction. Although the existence of the latter two effects has previously been regarded as damaging to balance theory, it was shown that these effects could be interpreted from a balance perspective and that balance theory could be used to generate supportable propositions regarding these effects. Thus in agreement with a unit-relation interpretation it was shown, in accordance with balance theory, that positivity effects are obtained when the subject, or p, assumes future contact with o, that reverse positivity effects are obtained when the subject anticipates breaking off contact with o, and that no positivity effect is obtained when there is absolutely no contact, past or future. It was also demonstrated in an experiment involving the p?o?q triad that, in accordance with balance theory, positivity effects may be produced by the assumption or inference of same-sign reciprocation in sentiment. Evidence for two balance processes underlying agreement effects was also found. One of these processes was based on the assumption that the subject would have or reveal psycho-logical reasons for the disagreement and thus produce imbalance. Consistent with this interpretation it was found that the agreement effect was significantly larger when future contact with discussion of x was assumed than when future contact without discussion of x was assumed. The other, or unit-relation interpretation was supported by evidence indicating that the breaking off of contact resulted in a reversed agreement effect. In general, it was argued that balance theory did quite well in such phenomenological investigations when attention was not narrowly restricted to the three-sign pattern but considered other potential cognitive bands.
