How to make smart decisions more easily

TED-Ed

This animated lesson explores the psychological phenomenon of "decision fatigue," explaining why our ability to make good choices deteriorates after a long period of decision-making. Through the lens of a fascinating 2011 study on parole judges, the video demonstrates how cognitive exhaustion can lead to impulsive behavior or the avoidance of making decisions altogether. It breaks down the variables that contribute to this state, such as decision frequency, complexity, and novelty. The video delves into the biological reality that mental work consumes physical energy, creating a daily threshold for high-quality decision-making. It highlights the dangers of this fatigue in high-stakes professions like medicine and law, where exhaustion can lead to critical errors. The narrative moves from systemic issues to personal application, helping viewers understand their own cognitive limits. For educators, this resource offers practical strategies for students to manage their own mental energy. It provides actionable advice on combatting fatigue, such as simplifying daily routines, delegating choices, and tackling important tasks earlier in the day. It serves as an excellent tool for teaching executive function skills, self-regulation, and psychology concepts related to willpower and mental stamina.
