Information Acquisition Bias during the Preparation of Group Discussion

Abstract

The present research investigates whether prospective minority and majority members exhibit information acquisition bias to exert social influence in a forthcoming group interaction. In particular, the question of whether (a) the mere fact of attending to a forthcoming group discussion and (b) group decision rule (majority rule vs. unanimity rule) alter the orientation toward supporting evidence is investigated. This study found that minorities exhibit greater information acquisition bias than equal and majority factions, especially when the minorities expected a group interaction. Group decision rule did not have any significant effect. The absence of effects of group decision rule and the relationship between coalition formation and cognitive processes are discussed.
