Fooled by Randomness

Nassim Taleb explores how humans systematically underestimate the role of luck and randomness in life and markets, mistaking random outcomes for skill-based results. The book examines survivorship bias, skewed distributions, and the concept of "alternative histories"—what would happen if you relived events 1000 times. Taleb argues that things achieved through luck are vulnerable to being lost through luck, while those built with minimal luck are more resistant to randomness.
