You Can Be So Smart, You Can Become Stupid

TL;DR

High IQ can cause stupidity because a brain that predicts outcomes stops paying attention, leading to errors on simple tasks.

Key Points

• 1.High IQ creates strong predictive capability that backfires. Like a chess player reading 10 moves ahead, a high-IQ brain auto-completes patterns — hearing 'quantum mechanics' and assuming the double-slit experiment is next.
• 2.Prediction short-circuits attention. Once the brain reads a situation to its conclusion, it disengages from active listening or task execution, opening the door to careless mistakes.
• 3.The errors appear on simple tasks, creating a paradox. A highly intelligent person making basic mistakes looks indistinguishable from someone who is genuinely stupid, blurring the line between the two extremes.
