What is it?

Decision fatigue describes the decline in decision quality that occurs when users are required to make too many choices over a short period of time. As fatigue increases, users are more likely to delay, abandon, or choose default options.

Decision fatigue is particularly relevant in long or complex journeys.

Examples in Action

• Large product catalogues without filtering or guidance
  
• Long multi-step forms with repeated choices
  
• Excessive configuration or customisation options
  
• Checkout flows with many decision points
  

Typical Outcomes / Results

• Increased drop-off or abandonment
  
• Lower satisfaction and confidence
  
• Improved performance when choices are simplified
  
• Clear optimisation opportunities through prioritisation
