Noise: A Flaw in Human Judgment discussed the troubling reality that human beings are pretty bad at making judgements. It means that the same individual may make very different decisions depending on the time of day, when they are hungry or tired, when the patient or defendant reminds them of their aunt Olga, and also when their prejudices, large or small, are triggered. And of course there are big differences between individuals, too.
Cue in misdiagnoses, bad hires, and strangely inconsistent prison sentences. So this is clearly an important problem, and the book contains useful and pretty simple suggestions to minimize it such as defining guidelines, cross-checking between evaluators, and minimizing the influence of first impressions, especially in groups.
That said, and despite its short chapters, the first half of the book is often uncomfortably technical if you don’t love statistical theory, and there’s quite a bit of repetition between chapters (perhaps because there are three authors?), which makes for a bit of a slog. Hang in there for the second part!
