Shaping reality vs. hiding from reality: Reconsidering the effects of trait need for closure on information search

For tentative and final decisions on real and artificial issues, three studies revealed a positive relation between trait need for closure and selective approach to supportive (vs. unsupportive) information. Specifically, individuals with high (vs. low) trait need for closure selected more decision-supportive information and less decision-challenging information for viewing. Furthermore, Study 1 showed that the effect of trait need for closure functioned independently of authoritarianism and dogmatism, and Study 3 showed that the effect of trait need for closure on selective approach to decision-supportive information was mediated by a current concern to get closure on the experimental issue. These findings provide a new understanding of how trait need for closure shapes post-decisional information search and decision making.

► Heightened trait need for closure was associated with a stronger selective approach to supportive information.
► Effects of trait need for closure were attributed to a current concern for closure.
► The findings shed new light on how trait need for closure shapes information search.
