@stephenpetro411: In a few medical fields — reading certain X-rays, certain heart sounds — physicians actually get *less* accurate the longer they've practiced. And it's not just doctors. Tested blind, wine "experts" barely beat ordinary drinkers. Financial forecasters don't reliably beat novices. Experienced programmers don't outperform CS students. The cause is a trap built into how we learn, documented across the nearly thousand-page *Cambridge Handbook of Expertise*: the moment a skill goes automatic, it feels like mastery — but your improvement secretly stops. Inside, I break down the one thing experts who keep improving do differently. #Expertise #Learning #SkillBuilding #CognitiveScience #SelfImprovement
