    Imagine standing before a judge who slept poorly and whose favorite team just lost. Without realizing it, he sentences you to three years-while yesterday, an identical case received six months from a different judge. This isn't dystopian fiction but the reality of what Daniel Kahneman calls "noise"-unwanted variability in judgments that should be identical. While we obsess over bias (systematic errors in one direction), noise (random scatter in all directions) remains largely invisible yet equally destructive. Using a shooting range metaphor, bias is like consistently missing the target in the same direction, while noise is like shots scattered randomly around the bull's-eye. The shocking reality? Noise pervades our most important institutions: doctors disagree on diagnoses, asylum decisions depend on which judge you get, and insurance underwriters quote wildly different premiums for identical risks. What makes noise particularly insidious is that unlike bias, which sometimes reveals itself through patterns, noise remains invisible without deliberate measurement-and when organizations finally measure it, they're typically shocked by what they find.
