Decision Fatigue

The deteriorating quality of decisions made by an individual after a long session of decision-making, or when confronted with too many choices simultaneously. Decision fatigue disproportionately affects people with executive dysfunction, ADHD, and other cognitive disabilities, as each decision consumes limited cognitive resources. In accessible design, reducing unnecessary choices, providing sensible defaults, using progressive disclosure, and offering curated recommendations can mitigate decision fatigue and improve usability for all users.
