Recent Research on Selective Exposure to Information

New research is described, including the experiments designed to specify those factors most important in influencing informational selectivity: the effects of choice and commitment on selective information seeking, selectivity and refutability of arguments, the amount of available information and its usefulness, the usefulness of decision reversibility, as well as the intensity of dissonance.

Abstract

This chapter highlights the recent research on the selective exposure to information. The term "selective exposure" implies several assumptions concerning the decision-making process. It assumes that the seeking out of decision relevant information does not cease once a decision is made. This notion also implies that this post-decisional information seeking and evaluation is not impartial but, rather, is biased by certain factors activated during the decision-making process. This chapter discusses the fundamental theses of dissonance theory as it relates to selective exposure and gives a short overview of the early research. This chapter describes new research, including the experiments designed to specify those factors most important in influencing informational selectivity: the effects of choice and commitment on selective information seeking, selectivity and refutability of arguments, the amount of available information and its usefulness, the usefulness of decision reversibility, as well as the intensity of dissonance. This chapter reports the results on some additional variables-cost of information, the reliability of dissonant information, and the effects of personality.
