#598 The Biology of Doomscrolling
Jul 31, 2026 · 7m
Summary
Dr. Robert Puff explores the biological roots of doom scrolling, explaining how our evolved negativity bias makes us vulnerable to algorithmic threats. He illustrates this trap using John Nash and Ray Bradbury’s work, showing how constant news consumption fuels anxiety rather than safety. To break the cycle, he advises labeling the threat response, replacing scrolling with grounding rituals, and charging phones away from the bedroom to protect inner peace.
