Curable

To explain the glitch, Christofferson leans on the psychology that Daniel Kahneman and Amos Tversky built over decades — work that eventually earned Kahneman a Nobel Prize in economics, in 2002, for showing that human judgment runs on predictable, systematic errors rather than cool rationality. We don't weigh evidence neutrally. We latch onto a first impression and then, mostly without noticing, gather reasons to confirm it. Confirmation bias, the tendency to see what we already expect, isn't a weakness of the careless. It's a feature of how every brain, including the trained ones, sorts the world.

Now drop that mind into a clinic. A doctor sees a patient, forms a fast intuition, and from that moment the evidence starts to bend toward the initial read. Contradictory test results get explained away; confirming signs get noticed. The same machinery that lets an experienced physician diagnose in seconds can also lock in a wrong answer and defend it. Intuition, the thing medicine most prizes in its best practitioners, is precisely the faculty most vulnerable to invisible bias.

The book's most memorable analogy comes from a game. For most of its history, baseball was run on the gut instinct of scouts and managers — men who trusted the way a player looked, swung, and carried himself. Then a wave of statisticians, most famously the outsiders who inspired Michael Lewis's Moneyball, showed that a lot of that expert intuition was simply wrong. The numbers identified value the eye missed and exposed traditions that had persisted only because no one had measured them. The teams that embraced the data started winning against richer rivals.

Christofferson calls his proposal a moneyball approach to medicine, and the parallel is exact. Baseball was an old, confident, tradition-soaked field full of genuine experts whose judgment turned out to be systematically distorted. So is medicine. The scouts weren't stupid; they were human, and humans over-trust the stories their intuition tells them. What changed baseball wasn't smarter people. It was a willingness to let rigorous data override the confident hunch — and to accept how often the hunch had been wrong.

The broadest claim in Curable is that we have been trying to fix medicine at the wrong level. We keep looking for better doctors — more brilliant, more objective, more heroic — when the real leverage sits in better systems. If human beings reliably misjudge evidence, no amount of individual virtue solves it. What solves it is designing the surrounding structure so that ordinary, biased, overwhelmed people are caught before their errors reach a patient. It's a shift from a morality tale to an engineering problem.

This is why Christofferson dwells on checklists, decision-support tools, and treatments that regulatory bodies overlook not because they fail but because no institution has an incentive to champion cheap, unpatentable therapies. The failures he catalogs aren't mostly failures of character. They're failures of design — systems that reward the profitable intervention, that never build in the routine second look, that leave a single tired physician to hold complexity no single mind can hold. Change the structure and you change the outcome without needing anyone to become a better person.

Curable ends where it began, on the gap between what American medicine spends and what it delivers — but the gap now reads differently. It is no longer just an indictment of corporate villains, though they remain in the frame. It is a portrait of a field practiced by capable people whose minds work the way all minds work, inside a structure that magnifies rather than corrects their errors. The radical mastectomy, the overlooked therapy, the confident wrong diagnosis: each is less a scandal of intent than a scandal of design.
