Hitting the Target: Accuracy vs. Precision
Notas do episódio
Using Jono’s sketch of four archery targets, we discuss why and how accuracy and precision differ.
Using many different examples, we frame the distinction as “accuracy being true to intention and precision being true to itself,” also phrased as doing the right thing versus doing it right.
The sketch is inspired by Simon Winchester's book, Exactly, where precision and accuracy are connected to the industrial revolution via Henry Maudsley’s innovative screw-cutting lathe, micrometer, and the concept of interchangeable parts. The conversation broadens to explore examples in food (McDonald’s vs artisan meals), recipes, recruiting, IQ tests (validity vs reliability), indoctrinated beliefs, gut feelings, culture’s return to individual craftsmanship, AI’s variable answers, LED mask wavelength tolerances, and targeting weapons.
