Imagine a disease affects 1 in 1,000 people. A test for it is 99% accurate. If you test positive, what are the chances you actually have the disease? Most people, including seasoned doctors, intuitively say 99%. The real answer is barely 9%. This massive cognitive failure costs lives and fortunes every day.The Base Rate Fallacy is our brain's tendency to ignore general statistical information in favor of specific, vivid details. We are biologically wired for narrative, not probability. When a jury hears an emotional witness, or an investor sees a flashy new tech startup, they completely discard the underlying historical odds of a false positive or a market failure, making catastrophic decisions based on isolated evidence.This book unpacks the dangerous mechanics of probability blindness. It walks through high-profile courtroom failures, medical misdiagnoses, and financial collapses, proving how even the smartest professionals fall victim to their own neurological blind spots.Rewire your brain to see the hidden math of reality. Master the basics of Bayesian thinking, overcome the seduction of specific details, and make decisions grounded in statistical truth.

Why doctors, juries, and investors constantly misunderstand probability and how to fix your statistical blind spot.
