Cleaning out the inbox this week. A pile of clips and stories people have sent me have been sitting there long enough, so let’s debrief.
We start with the Jonah Hill jiu-jitsu clip that went viral, the perfect illustration of the Dunning-Kruger effect: a little training turns into “I can beat people up,” while the guys who’ve actually been on the mats for years get quieter and more humble the more they learn. Then the tech bros. Zuckerberg sparring on a custom floating platform in the middle of a lake, and how that stacks up against the story of his super-yacht reportedly passing on a distress call, when helping is one of the oldest rules on the water.
Then the one that got under my skin. Gordon Ryan taking a student’s purple belt and throwing it in a fire, on camera, as a “reward.” One of the best grapplers alive, and a masterclass in how not to treat people who trust you. We finish with the antidote: Gabriel Varga, five-time world champion, breaking down how a real professional spars with people who aren’t. Playful, controlled, take turns, let them learn. That’s the standard.
In this episode:
What good sparring actually looks like, from someone who’d know
The Dunning-Kruger effect and the blue-belt fallacy
Why the more you learn, the more you realize you don’t know
Performative toughness vs. the real thing
The unwritten (maybe written) rule of the sea and what it says about character
Why filming yourself humiliating a student makes the whole thing unserious
