The effects of accountability, justification and consensus on a decision-maker's information search behavior

"This study attempted to address three major issues. First, to extend the Information Search model (Cooper and Sniezek, 1990) to explain the decision-making process under varying levels of consensus and accountability. Second, to examine, in detail, the relative effects of inter-adviser consensus and judge-adviser consensus on the decision-making process. Third, to enhance the conceptualization of accountability (Tetlock, 1983) as a psychological phenomenon. The method employed was a simulated Judge-Adviser System, in which all subjects were judges. The subjects made decisions regarding a hypothetical investment decision. The subjects had the option of obtaining information from their ""advisers"" to aid in the decision-making process. A 2 x 2 x 2 x 2 factorial design was used with inter-adviser and judge-adviser consensus forming the first two factors and accountability and justification forming the remaining factors. Dependent measures included, confidence levels, amount of information search, and decision revision. Results indicate that the information search model is generally supported. Judge-adviser consensus has strong effects, although inter-adviser consensus resulted in some interesting interactions with accountability. Last, accountability and justification resulted in different decision-maker behaviors in terms of information search and confidence."
