# What is Decision Fatigue ?

Quick Answer

Decision fatigue is the deteriorating quality of decisions made after a long session of decision-making. The brain's decision-making ability depletes like a muscle.

## Understanding Decision Fatigue

Research by Roy Baumeister and colleagues demonstrated that decision-making draws from a finite pool of mental energy. Each decision—no matter how small—depletes this resource, leading to progressively poorer decisions, increased impulsivity, or complete decision avoidance. A famous study showed that judges granted parole at a 65% rate after breaks but nearly 0% by the end of decision sessions. In sales, presenting buyers with too many options, requesting multiple decisions in sequence, or scheduling important conversations at the end of the buyer's day all contribute to decision fatigue.

### Key Takeaways

-   1 Decision quality deteriorates with each successive decision 
-   2 Judges grant parole at 65% after breaks, near 0% at session end 
-   3 Too many options lead to decision avoidance 
-   4 Timing of requests significantly impacts outcomes 

## How to Apply Decision Fatigue in Sales

Schedule proposal reviews and key decisions for morning meetings. Reduce the number of choices you present—three options maximum. Pre-make low-stakes decisions for the buyer ("I've already selected the best configuration for your use case").
