Noise: A Flaw in Human Judgment
Kahneman's final major work distinguishes between bias (systematic error) and noise (random variability in judgments). Noise is at least as damaging as bias in investing, and organizations are largely unaware of how much it distorts decisions. The 'decision hygiene' protocols are immediately implementable. The same analyst, the same data, different days — wildly different conclusions.
An article's worth of insight stretched over four hundred pages of committee prose; three authors, and it reads like the minutes of their meetings. Underwriters, judges, and radiologists cycle past until the bias-versus-noise distinction blurs from repetition, and the behavioral science underneath arrived already dented by the replication crisis. Most readers need the first fifty pages; the rest is reiteration.
The case for it and the rest of the canon open with Pro.
