Why You Are Less Competent at 5:00 PM: The Deep Dive

This week Alex and Emily are discussing decision fatigue, the measurable decline in judgment quality that happens after extended decision-making. They go beyond the usual Steve Jobs wardrobe stories to explore alarming research: Israeli judges whose parole approval rates dropped from 65% to nearly zero by the end of each session, surgeons who become dramatically more conservative as their shifts progress, and the “morning morality effect” showing that ethical lapses are more likely in the afternoon.

The episode connects decision fatigue directly to executive burnout and offers practical strategies for protecting cognitive capacity. If you’ve ever wondered why your 4pm judgment feels different from your 9am clarity, this one explains why.
