Why your brain runs out of fuel after making too many daily choices

How to make smart decisions more easily · 5:16 · Video: TED-Ed · Watch at the source

In short: Every decision you make consumes mental energy. This video explores the psychology of decision fatigue, explaining why extended periods of choosing lead to cognitive exhaustion and offering strategies to manage your daily decision-making threshold.

Mental and physical activities both require energy. Research indicates that individuals possess a finite capacity for decision-making each day. When this threshold is exceeded, the resulting state of cognitive exhaustion can impair your ability to make smart choices.

The video, developed with insights from Evan Polman and in collaboration with Character Lab, examines the specific types of choices that trigger this fatigue and provides practical methods to mitigate its effects.
