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.

This discussion centres on “overnight success” as an illusion; prompted by Jono’s sketch of Twitter Cofounder, Biz Stone’s quote: “Timing, perseverance, and 10 years of trying will eventually make you seem like an overnight success.”
In this fun and nostalgic conversation, we discuss Jono's observation that with indoor games especially, as the momentum builds, you keep playing until something gets broken! There's a cheeky inevitability to it. It's a situation we've almost all certainly been in - whether you were the protagonist or not!
US Navy submarine captain and author David Marquet discusses leadership lessons from turning the USS Santa Fe from worst to best, focusing on “pushing authority to information” rather than pushing information up a hierarchy. Marquet critiques industrial-age leadership language that seeks obedience and creates “bobblehead” agreement, arguing that real engagement comes from giving people decision-making authority,
