What it's about

Gladwell argues that snap judgments made in the first two seconds of encountering something can be as accurate as, or more accurate than, decisions made after extensive deliberation. Drawing on psychology research and real-world cases, he shows how the unconscious mind rapidly sifts experience for patterns, sometimes outperforming conscious analysis. The book mattered because it challenged the reflexive assumption that more information and more time always produce better decisions, while also warning that snap judgments can encode bias as easily as expertise.

6
Blind Auditions and the Fix for Biased Intuition
Bias built into snap judgment can be neutralized not by trying harder to be fair, but by redesigning the situation so irrelevant information never reaches the decision-maker.

Reading a Room in Seven Seconds: The Limits of Thin-Slicing
