It Didn't Get Worse — It Just Came Back

🎯 A hundred people sit the same test twice. A score is «skill + luck». Keep only the ten who did best in round one, look at round two, and the average drops sharply — yet nobody got worse. The ten who did worst go up instead. Both simply came back toward the «middle». Picking the top scorers does not pick skill alone; it also picks «whoever was lucky that day», and that luck does not follow them. 🎲 Second, the check. Turn «luck's share» down to zero and the two rounds become identical, and the drop is exactly zero. The more luck there is, the further it falls on its own — and skill was never touched. 📰 Third, the judgement. You praised someone after a brilliant day and they did worse; you scolded after an awful one and they improved. Did the praise ruin it? This app was made with code too · Remix it and change luck's share.
