Noise: A flaw in Human Judgment by Daniel Kahneman, Olivier Sibony, and Cass Sunstein (2021)


Noise for the purpose of this book is defined as "undesirable variability in judgments of the same problem."  Kahneman and team focus on the statistics of the phenomenon and are careful to separate this concept of "noise" from cognitive bias. The book covers many motivating institutions in human resources, government, and businesses such as insurance underwriting. Kahneman's  Thinking Fast & Slow is one of my top five life-changing books so I had high expectations when I started reading.  The book covers similar themes to Taleb's Fooled by Randomness, but with much more rigor, precision, and depth. I really loved how the authors brought in all of the opposing points of view and criticisms, explained why some of them have merit and must be considered, and why others should yield to their approach of rigorous statistics and measured outcomes. The book is a little bit long but extremely worthwhile, 5/5 Stars.  Highly recommended.
