Title: How people search online consumer reviews: Theory of search and practical implications

Abstract: Consumer reviews have become a key resource, supported by web retailers and valued by consumers.  This talk examines how people search online consumer reviews to inform decision making. It firstly examines whether a theory of searching for information to discriminate between alternative choices can explain behavior, and contrasts it to the normative theory. Partly in accord with the theory, the results of a controlled experiment show that in an environment dominated by positive reviews, such as the World-Wide Web, people gather more information for the best alternative under consideration, and they take more time to inspect reviews of lower rating. Theoretical implications are examined, and a bounded optimal account of the way in which people acquire information in service of decision making is proposed. Finally, practical implications for the design of e-commerce web sites and online opinion forums are discussed.
