Abstract

This article describes a cognitive argumentation schema for written arguments and presents three empirical studies on the “myside” bias—the tendency to ignore or exclude evidence against one's position. Study 1 examined the consequences of conceding, rebutting, and denying other-side information. Rebuttal led to higher ratings of agreement and quality and better impressions of the author than when the same arguments excluded other-side information (i.e., exhibited the myside bias). In Study 2, claims had a significantly greater impact on agreement ratings and reasons had a significantly greater impact on quality ratings. When participants were given myside reasons supporting other-side claims, they acknowledged argument strength while making relatively minor changes in agreement. In Study 3, the authors found that a brief, theoretically motivated written tutorial was effective in improving undergraduate students' written argumentative essays by significantly increasing the precision of claims, improving the elaboration of reasons, and reducing the myside bias.
