Hitting the Target: Accuracy vs. Precision

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.External linksAlso referenced in this episode:Jono's sketch that describes the difference between Reliability and Validity.Jono's sketch inspired by Roger Martin's Knowledge Funnel.Jono's sketch outlining The Beard Cycle.Episode Outline00:00 Accuracy vs Precision: the Four Target Sketch03:23 True to Intention04:11 Ball Through Window05:44 Precision Built World09:45 Food and Recipes13:27 Calibration and Scales14:47 Manufacturing Tolerances16:51 Hiring and Testing19:16 Beliefs and Education23:01 Culture and Craft26:09 Doctors Robots and AI29:03 Wrap Up and CreditsAll music on this podcast series is provided by the very talented Franc Cinelli and you can find more tracks at franccinelli.com Hosted on Acast.
