درباره این اپیزود
In the movie about the bin Laden raid, an analyst says "one hundred percent he's there." The real room gave Leon Panetta a spread — 90, 60, below 50 — and he had to make the call on a gut. Around that same time, American intelligence quietly ran a four-year tournament to find out whether anyone can actually predict the future. The winners were a pharmacist and a retired programmer with a duck for an avatar.
This episode teaches the method they used, move by move: start from the base rate, break impossible questions into estimable pieces, commit to precise numbers — 63%, not "probably" — update small and often, team up and let math sharpen the crowd's answer, and keep score with Brier scores, the scoreboard the whole field runs on.
Then the part most tellings skip: where it breaks. The curated questions; Taleb's rare-event attack and Tetlock's own concession; the Ukraine and Brexit misses; the AI progress the superforecasters underpriced — priced at 2.3%, resolved yes.
And the 2026 twist, in two industries. A betting-market war: Kalshi reportedly chasing a $40 billion price tag while New York sues and a federal regulator invokes emergency powers to keep it open. And AI systems that reached statistical parity with the superforecaster median — by having the method typed into their prompts: "You are an expert superforecaster… pick the base rate." The superforecasters' own median forecast says AI beats them by 2028. The best calibrators on Earth, calibrated about losing.
You can practice the skill free — Good Judgment Open and Metaculus run public tournaments with real scoreboards. The skill was never seeing the future. It was keeping score on yourself, before reality does it for you.
