Certainty in holistic thinking and responses to contradiction: Dialectical proverbs, counter-attitudinal change and...

The present research examined whether consideration of individuals' certainty in their holism can enhance the ability of this individual difference to predict how they respond to contradiction-relevant outcomes. Across four studies, participants first completed a standardized measure of holistic-analytic thinking. Then, they rated how certain they were in their responses to the holism scale or were experimentally induced to feel high or low certainty. Next, participants were exposed to dialectical proverbs (Study 1a and 1b), to a counter-attitudinal change induction (Study 2), or to a paradigm of attitudinal ambivalence (Study 3). Results revealed that participants with higher certainty in their holistic thinking exhibited higher preference for dialectical proverbs (Study 1a and 1b), changed their attitude less following a counter-attitudinal task (Study 2) and showed weaker correspondence between objective and subjective ambivalence (Study 3). Beyond examining new domains and discovering novel findings, the present work was designed to be the first to show moderation of previously identified effects in the domain of holistic thinking and responses to contradiction.
