Information dimension, information overload and decision quality

The impact of information load (both under and overload) on decision qualit y is an important topic, yet results of empirical research are inconsistent . These mixed results may be due to the fact that information load itself i s a function of information dimension. A meta-analysis of 31 experiments re ported in 18 empirical bankruptcy prediction studies was conducted to test the effect of two information dimensions: information diversity and informa tion repetitiveness. Results indicated that both information dimensions hav e an adverse impact on decision quality: provision of either diverse or rep eated information can be detrimental to prediction accuracy. The findings h ave implications for information suppliers and researchers who are interest ed in improving the quality of human decision making.
