Noisy, without much signal – that's the unfortunate feel of the 2021 tome Noise: a Flaw in Human Judgment. Authors Daniel Kahneman and Cass Sunstein are semi-celebrity scholars; their co-author Olivier Sibony less so. Their joint work here lacks coherence, stylistic sparkle, or novel substance. Some bottom lines, from the "Review and Conclusion":

• The goal of judgment is accuracy, not individual expression.
• Think statistically, and take the outside view of the case.
• Structure judgments into several independent tasks.
• Resist premature intuitions.
• Obtain independent judgments from multiple judges, then consider aggregating those judgments.
• Favor relative judgments and relative scales.

OK, and ...?
