The article reviews the choice overload hypothesis, which posits that an increase in the number of options available can lead to adverse consequences such as decreased motivation to choose or satisfaction with the chosen option. The authors conducted a meta-analysis of 63 conditions from 50 experiments (N = 5,036) to examine the empirical evidence for this hypothesis. The mean effect size was found to be virtually zero, but there was considerable variance between studies. Further analyses indicated that choice overload is not a general phenomenon and identified specific conditions under which it may occur. The review also discusses potential moderators of choice overload, including the structure of the assortment, decision-making strategies, and the perception of the distribution of options. The findings suggest that while choice overload is not a robust phenomenon, certain conditions may increase its likelihood. The article concludes by highlighting directions for future research to better understand when and why choice overload reliably occurs.The article reviews the choice overload hypothesis, which posits that an increase in the number of options available can lead to adverse consequences such as decreased motivation to choose or satisfaction with the chosen option.
