What is the relationship between information overload and decision fatigue?

Information overload directly contributes to decision fatigue. Information overload is a state where an individual is exposed to too much information, making it difficult to process and understand. Decision fatigue, on the other hand, is a state of mental exhaustion that results from prolonged decision-making. When someone experiences information overload, they are faced with a large volume of options and data, which requires significant cognitive effort to evaluate and compare. This constant evaluation process depletes mental resources, leading to decision fatigue. As decision fatigue sets in, individuals become more prone to making impulsive or irrational decisions, avoiding decisions altogether, or relying on simple heuristics rather than carefully weighing the options. For example, someone overwhelmed with numerous choices when online shopping might simply choose the first item they see or abandon their cart entirely due to decision fatigue. The more information one has to process, the more demanding the decision-making process becomes, and the more susceptible one is to experiencing decision fatigue, which negatively impacts the quality of decisions.
