A two‐valued logic or two‐valued balance resolution of the challenge of agreement and attraction effects in p‐o‐x triads, and a theoretical perspective on conformity and hedonism

Investigated the effect of three different variables on agreement effects in p‐o‐x triads. The subjects were 740 male and female undergraduates at the University of North Carolina. Experiment 1 found that assumed similarity modified the agreement effect—but only on cognitive rating scales (expectancy, consistency, stability). Experiment 2 found that assumed knowledgeability of o regarding × modified the agreement effect on both affective (pleasantness, harmony) and cognitive (expectancy, consistency, stability) scales. Experiment 3 found that a manipulation of o to p liking that was either consistent or inconsistent with p and o agreement modified the agreement effect primarily on the affective scales.
