Noise: A Flaw in Human Judgment

Why I recommend it

I’m drawn to books about decision making and bias, and this adds another useful way to think about judgment. People can look at the same information and reach very different conclusions, even when we expect consistency. The authors give us frameworks for noticing that variation and doing something about it.

What stayed with me

I love the noise audit concept: have people independently assess the same cases, then compare their judgments. It gives a team a way to see differences that might otherwise stay hidden. That feels like a useful place to begin before assuming everyone means the same thing by a good candidate or strong performance.

Who it’s useful for

Leaders, managers, and anyone involved in hiring, performance reviews, or other decisions where consistency matters. Also worth a look if you’re interested in how people think and why judgment can be so unreliable.

A tension or limitation

It’s a bit dense. There are ideas here worth trying, but putting them into practice takes more than recognizing the problem. And consistency alone doesn’t mean a decision is fair or right; a whole team can share the same bias.
