概要

Every high-stakes domain has a version of institutionalized dissent. Military intelligence formalized it after the 1973 Yom Kippur War. Aviation built it into accident investigation after Challenger. Medicine invented controlled trials to distrust the doctor's own judgment. Finance rewards the contrarian fund manager who is structurally required to find reasons not to invest.

This show documents that pattern and tells a human story about what happens when everyone agrees and what that can cost.

Each episode takes one domain and one moment where consensus failed catastrophically, then traces how that domain responded by building opposition into its structure.

  • The Room Where It Happened Twice
    2026/04/15

    In April 1961, fifty of the most experienced foreign policy minds in America sat in a room and agreed to invade Cuba. The Bay of Pigs was over in three days. Afterward, President Kennedy asked the question that still haunts every organization that gets it wrong: "How could we have been so stupid?"

    Thirteen months later, the same president, in the same office, with many of the same advisors, faced Soviet nuclear missiles in Cuba. He got it right the second time. The difference was the structure of the room.

    This episode traces what went wrong in the Bay of Pigs decision. The self-censorship, the mindguards, the assumed consensus. And why a Yale psychologist coined the term "groupthink" specifically to describe it. It traces what Kennedy changed for the Cuban Missile Crisis: removing himself from meetings so his advisors could think without deferring. Turning a mindguard into a devil's advocate. Splitting the group into subgroups. Inviting outside challengers. Building a moot court to stress-test every option.

    Same man. Same office. Same advisors. Different structure. Different outcome.

    The episode also examines why the groupthink diagnosis may be partly wrong, and why the prescription works regardless.

    Episode 6 of The Tenth Man. New episodes weekly.

    Show Notes:

    This episode covers the Bay of Pigs invasion (April 1961), the Cuban Missile Crisis (October 1962), Irving Janis's groupthink theory, and Roderick Kramer's revisionist "politicothink" critique. It traces the structural changes President Kennedy made between the two crises and maps them to the failure modes documented in the first five episodes of the series.

  • The Most Expensive Opinion in the World
    2026/04/08

    In 2005, a failed analyst with a last-chance desk job built a chart from decades of housing price data. The chart showed a bubble. His boss bet everything on it. Two years later, the firm made $15 billion.

    In between: daily losses, investor revolts, professional ridicule, and a financial system designed to destroy anyone who disagrees with the consensus before the consensus has time to be proven wrong.

    This episode is about the structural cost of financial dissent. Short selling - betting against the market - is the only form of dissent that charges you money every day you hold the position. The consensus is free. The challenge compounds. And if your timing is wrong, you are liquidated - often because the market stayed irrational longer than your capital could survive.

    Show Notes:

    The 1.4% annual inflation-adjusted housing price growth figure (1975-2000) is from Zuckerman's account of Pellegrini's research, which drew on Case-Shiller data. The specific figure is widely cited but represents Pellegrini's own calculation from his compiled database, not a standard published metric.

    The "markets can remain irrational" quote attribution is covered in detail by Quote Investigator (2011). The earliest documented print appearance is A. Gary Shilling in Forbes, February 1993, with an earlier likely oral use traced to Shilling in 1986. Keynes received credit by 1999. The episode presents this as a misattribution, consistent with the show's treatment of the "Tenth Man" naming in Episode 1.

    The 489% Scion Capital return (net of fees, November 2000 - June 2008) is from Scion's own records as reported in multiple sources including Wikipedia and Lewis. The S&P 500 comparison figure (~2% over the same period) is from Law Street Media's reporting.

  • The Industry That Learned to Fail
    2026/04/01

    In 1968, your odds of dying on a commercial flight were roughly 1 in 350,000. By 2022, that number was 1 in 13.7 million. Aviation didn't get there by building better planes. It got there by building a system that treats every failure as information - and that makes it structurally impossible for a crash to be documented and then forgotten.

    This episode traces that system from Tenerife in 1977 - where a flight engineer asked the right question and was overruled in four words by the most senior pilot at KLM - through Portland in 1978, where a first officer watched the fuel run out because the culture taught him to hint rather than assert. It follows Crew Resource Management from its origin to its proof case: United Flight 232 in 1989, where Captain Al Haynes invited a passenger into the cockpit and asked, "Why would I know more than the other three?" 185 people survived an unsurvivable situation.

    Then it follows the NTSB - the independent investigation architecture that turned crash data into mandatory public lessons for fifty years, producing the best safety record of any transportation industry in history.

    And then it follows the Boeing 737 MAX. 346 people dead. A flight control system erased from the pilot manual before any pilot could object to it. The safety architecture selectively dismantled for a commercial incentive.

    The distance between Tenerife and Sioux City is what institutional design can accomplish. The distance between the NTSB's fifty-year record and the 737 MAX is what happens when that design is selectively abandoned.

    Show Notes:

    The 1 in 350,000 figure (1968–1977) and 1 in 13.7 million figure (2018-2022) are from the MIT/Barnett study and represent global commercial aviation passenger boarding fatality risk. These are the most rigorous publicly available estimates.

    The 96% self-certification figure is sourced from the PMC engineering ethics paper citing Kitroeff et al. 2019 (New York Times reporting). Boeing contests aspects of how this figure was framed publicly; the DOT Inspector General report documents the delegation structure without using this precise percentage.
