In 2000, the American Academy of Pediatrics issued a recommendation that seemed sensible at the time. To protect children from peanut allergies, parents were told to avoid giving peanuts to infants and young children. The advice was logical. If peanuts cause allergic reactions, keep peanuts away from children. Doctors repeated it. Parents followed it. Schools banned peanut butter. Airlines stopped serving peanuts. An entire culture of avoidance took hold. There was only one problem. The recommendation was wrong. Over the following decade, peanut allergies in children tripled. Emergency room visits for severe allergic reactions soared. By 2019, roughly one in eighteen American children had a peanut allergy. The very advice intended to protect children had created an epidemic. This is not an isolated story. It is a pattern. Marty Makary, a surgeon and public health researcher at Johns Hopkins University, has spent his career investigating why modern medicine, for all its brilliance, so often gets things wrong. In *Blind Spots*, he examines the uncomfortable reality that many of the medical recommendations Americans have followed for decades were based on weak evidence, flawed assumptions, or institutional inertia rather than rigorous science. The problem is not that doctors are unintelligent or uncaring. The problem is structural. Medicine is a field that rewards conformity. Physicians are trained to follow protocols. Medical societies issue guidelines. Insurance companies reimburse based on those guidelines. Hospitals measure compliance. Challenging the consensus is rarely rewarded and often punished. When a recommendation becomes established, it takes on a life of its own. It gets repeated in medical schools, cited in journals, and embedded in practice. Over time, it becomes dogma. And dogma is resistant to evidence. Makary's central argument is that medicine has a blind spot problem. The field has developed remarkable tools for treating disease, but it has not developed equally strong tools for questioning its own assumptions. As a result, patients have been harmed by recommendations that were never properly tested. The peanut allergy story illustrates this perfectly. The 2000 recommendation was based on a…
