Since Alwin Toffler coined the term choice overload in 1970, no systematic literature review has been conducted on this subject. At the same time, the three meta‐analytic studies available on the topic does not provide a comprehensive picture of the same. This systematic literature review seeks to critically evaluate the extant research on choice overload for 22 years using insights from 92 articles. After locating the major articles in the choice overload literature, we identified the theories used by researchers to explain the various aspects of choice overload, based on the TCCM framework. We then enlisted the contexts where the studies had been conducted, the characteristics (themes) of the studies, and the methodologies used in these articles. We further identified the relationships between the themes, the variables studied so far, the sampling types and sampling sizes and the statistical tools employed in these studies. Future researchers could investigate the impact of a variety of cognitive and affective factors that impact consumer psychological states and the likelihood of choice saturation. They could also focus on unexplored areas in the field of choice overload, such as comparing the effects of choice overload in physical and online contexts.

二十多年来关于选择过载的研究：概述和研究议程

自从阿尔文·托夫勒 (Alwin Toffler) 于 1970 年创造了“选择超载”一词以来，尚未对这个主题进行系统的文献综述。与此同时，关于该主题的三项荟萃分析研究并未提供该主题的全面描述。这篇系统文献综述旨在利用 92 篇文章的见解，批判性地评估 22 年来关于选择超载的现有研究。在找到选择超载文献中的主要文章后，我们基于 TCCM 框架确定了研究人员用来解释选择超载各个方面的理论。然后，我们列出了进行研究的背景、研究的特征（主题）以及这些文章中使用的方法。我们进一步确定了主题、迄今为止研究的变量、抽样类型和抽样规模以及这些研究中使用的统计工具之间的关系。未来的研究人员可以研究影响消费者心理状态和选择饱和可能性的各种认知和情感因素的影响。他们还可以关注选择超载领域中未探索的领域，例如比较选择超载在物理和在线环境中的影响。
