The Signal and the Noise: Why So Many Predictions Fail - but Some Don't
An exploration of prediction success and failure across diverse domains
"The signal is the truth. The noise is what distracts us from the truth."
— Nate Silver
My Review
Silver's analysis of prediction across domains - elections, weather, earthquakes, baseball - provides practical frameworks for distinguishing signal from noise. This is environmental sensing made concrete and actionable.
Why It Matters
Silver provides domain-specific analysis of what makes predictions succeed or fail. His frameworks for separating signal from noise are directly applicable to organizational sensing.
Key Ideas
- More data doesn't automatically improve predictions - signal/noise ratio matters
- Overconfidence is the biggest prediction error
- Bayesian thinking updates beliefs with new evidence
- Prediction quality varies dramatically by domain
How It Connects to This Framework
Book 1's environmental sensing chapter and the signal detection concepts throughout.
