A month ago I got obsessed with one question.
Why do smart people make terrible decisions sometimes?
So I spent a month reading peer reviewed research instead of doing normal 14 year old things.
Kahneman proved stress collapses careful analytical thinking entirely. Baumeister proved every decision you make depletes a finite cognitive resource. Walker proved sleep deprivation destroys judgment before you consciously feel it. Monk proved your brain has specific peak performance windows based on when you woke up. Lieberman proved one cup of coffee helps but two hurts. Ratey proved exercise directly boosts the exact brain region responsible for complex decisions.
Six factors. All peer reviewed. All measurable.
