Episode Summary
Executive Summary: Michael Lewis frames this season of Against the Rules around “experts” and argues that true expertise is often hidden in low-status roles. Through Todd Park and medical biller Sue Henderson, the episode shows how healthcare billing complexity creates invisible specialists whose knowledge can transform businesses and systems, especially in crisis.
Main Topics: The central problem of expert blindness: Lewis argues American institutions are bad at identifying who actually knows the answer, confusing visibility, status, and confidence with real expertise. Todd Park’s search for the real expert: Todd Park’s early health-care startup revealed that the critical knowledge lived not with executives or doctors, but with an overlooked medical biller who understood insurance rules. Medical billing as hidden technical expertise: The episode shows billing as a deeply complex, rule-driven domain where tiny details determine whether providers get paid and survive financially. Sue Henderson as the underestimated expert: Sue’s practical mastery, moral certainty, and accumulated tacit knowledge made her indispensable, though she had little formal status or recognition. Turning human expertise into software: Athena Health’s breakthrough came from translating Sue’s head-based knowledge into code, creating a scalable rules engine and a major company. The 'L6' principle in government crises: Todd later applied the same lesson to healthcare.gov and other failures: the fix is often several layers down, where real operators and contractors understand the problem. Experts, crisis, and power: The episode links pandemic response, health care, and digital failures to the broader idea that societies fail when they listen to the wrong people.
Key Arguments: Expertise is frequently located far below formal authority; the people on TV or in charge may know least. Medical billing became so complex that providers depended on specialists whose knowledge was not documented anywhere, only accumulated through experience. Sue Henderson’s value came from tacit knowledge, pattern recognition, and willingness to say when something was wrong. Athena Health succeeded by encoding one person’s expertise into software, proving that overlooked know-how can become massive economic value. The healthcare system’s opacity and fragmented insurance rules create incentives for confusion, not clarity. In large crises, effective problem-solving requires finding the hidden operator or contractor who actually understands the system. People who seem unimportant can be the decisive experts because they are closest to the real work.
Data Points: Season count: 3 - Against the Rules season three focuses on experts. Stories in the season: 7 - Lewis says the season will tell seven stories about experts. Age of Todd Park when the story begins: 24 - He and a partner launched a pregnancy-care venture shortly after business school. Age of Michael Lewis in the archival interview: 31 - A radio host introduces Lewis as 31 in a vintage clip about Liars Poker. Years Ed Park worked intensely: 3 years - Ed Park worked long days coding Sue Henderson’s knowledge into software. Work hours: 18 hours a day - Ed Park’s early startup routine at Athena Health. Company valuation: $5 billion - The contents of Sue Henderson’s mind became a $5 billion software company. Insurance company count: A lot of different companies/products - Lewis describes a fragmented system with many insurance products and billing rules. Hospital payment issue: $250,000 - Sue found a quarter of a million dollars in unapplied Medicaid payments at one hospital. Layer depth in crisis response: 5 to 7 layers down - Todd and his teams repeatedly had to descend layers to find the people who understood the problem. Tenure measure: L6 - Todd uses “L6” to describe the key hidden expert, six levels below leadership. Replicated staffing ratio: 1 biller for 10 doctors - Athena Health’s software let one biller handle ten doctors.
Pivotal Quotes: "How come a society so great at creating knowledge is so bad at using it?" — Michael Lewis: Lewis states the core question driving the season about experts and institutional failure. "Find the L6." — Todd Park: Todd’s practical rule after healthcare.gov: locate the hidden person who actually understands the system. "I'm going to give you a little lesson." — Sue Henderson: Sue asserts authority and teaches the younger founders how medical billing really works.
Implications: The episode suggests organizations should stop equating status with competence and build systems to surface hidden expertise. In healthcare, tech, and government, success may depend on finding and empowering the people closest to the real work.
From the Episode
Our first season was about referees. Our second was about coaches. This season's about experts. We're going to tell seven stories about them. Each contains a clue to a mystery at the heart of American life. How come a society so great at creating knowledge is so bad at using it? How can we know more and more yet behave as if we know less and less? How can one people be so incredibly smart and so breathtakingly moronic? The experts are terrible. The pandemic's taught us a bunch of things. That bosses miss the office more than their employees. That our centers for disease control aren't very good at controlling disease. That these United States aren't all that interested in being united, even in a crisis. Mr. President, please listen to your public health experts instead of denigrating them. But the pandemic's also taught us something about experts: how fraught our relationship with them has become.
Why the Obama administration hadn't found the people who knew how to fix their website on their own is a question for another day. But this kind of thing seems to happen over and over again. After the healthcare.gov debacle, Todd always sent his tech teams into any crisis with a specific instruction. Find the L6. I remember actually a report out from one of the teams. They had been deployed to the State Department because I believe it was the visa processing system of America that had broken. And that was a huge problem, obviously. And so he said, What did you do? He said, Well, I went seven layers down. Found two contractors who actually knew what the problem was. And he said, All I did was basically say, Okay, I'm going to take your solution and deliver it seven layers up and basically tell the people in charge, this technical fix needs to be executed. And it was, and then America was able to process visas again. Have you ever asked yourself why you?
With all of these brilliant programmers, that they could figure it out all by themselves, that they could just figure it out. It was a few days into it when Sue realized that Ed and I really had no idea what we were doing. And so she sits us down. She's like, boys, shut up. I'm going to give you a little lesson. And she taught us about how the accounting works. Bob Gatewood is remembering the day on the island when it became clear who was the Admiral Crichton. Well, after she gave us that lesson, we're like, oh, yes, we will follow you. We are your grasshoppers. And so, you know, she was basically the product manager at that point. So she, you know, she would tell us what the system needed to do, and we would go do it. And we bought her Hazel. Did she tell you about Hazel, the big printer? So we got her a big claims printer, and she named it after her mother. So we have a Gladys, a Hazel, and a Sue.
About Against the Rules
Michael Lewis’s best-selling book The Big Short is now 15 years old. The Oscar-winning movie based on it came out a decade ago. To mark the occasion, Lewis has narrated a new audiobook of The Big Short. Here on his podcast, he and co-host Lidia Jean Kott are thinking about the legacy of the book, the movie, and the financial crisis of 2008. Michael catches up with the director of the movie, Adam McKay, as well as some of the real-life characters depicted by the likes of Ryan Gosling, Steve Carell and Jeremy Strong. He also calls up journalists, economists, and historians to make sense of the 2008 financial crisis and to understand how it still affects the world today.
