Most studies that have manipulated only source-subject discrepancy have obtained an increasing linear relation between discrepancy and ch:inge, with evidence that the rela- tionship begins to decrease at the high extreme of advocated change (4, 5, 6, 8, 9). Manipulation of issue involvernent (5, 7) or of source of influence (1, 2, 3) results in a curvilinear relation between discrepancy and change. The interaction between source and tliscrcpancy can be explained by disso- iiance theory, which holds that incrrnsing discrepancy between a subject’s own attitude position and that of a soum of influence increases dissonance. Change of attitude in the advocated direction or disparagement of the source seems to be the major alternative mode of reducing dissonance in this situation. With a iieutral source and moderate levels of discrepancy,
