Part 2: How an Overvalued Belief Captured Medicine – Paul McHugh Explains More (#46)
At 93, Johns Hopkins psychiatrist Paul McHugh offers European clinicians and policymakers a rare historical map of how medicine loses its way. In this second conversation with Beyond Gender, he traces the anatomy of an overvalued belief — from the multiple personality disorder epidemic to recovered memory therapy — and places today's gender medicine squarely in that lineage. For a continent that produced the Dutch protocol and is now watching Sweden and Finland walk back paediatric transitions, his account of how bad ideas spread and are eventually stopped is anything but abstract.
Paul McHugh spent more than a quarter-century as Psychiatrist-in-Chief at Johns Hopkins Hospital, trained at London's Maudsley under Sir Aubrey Lewis, and has spent six decades arguing that psychiatry must anchor itself in empirical, brain-based evidence. In this second conversation with the Beyond Gender team — recorded in his ninety-third year — he returns to the question that has quietly shaped his career: how does a profession built on careful observation fall so completely under the spell of a single, unfounded idea? The concept he reaches for is the overvalued belief — a conviction held with such intensity that it overrides clinical evidence, silences dissent, and reshapes entire systems of care around itself. McHugh traces this pattern through some of psychiatry's most damaging chapters: the multiple personality disorder epidemic of the 1980s and 1990s, in which thousands of patients received a diagnosis he came to regard as largely iatrogenic — constructed by the expectations of therapists rather than discovered in patients — and the recovered memory wars, in which suggestive therapeutic techniques generated false accusations that destroyed families. His involvement with the False Memory Syndrome Foundation placed him at the centre of one of the most acrimonious disputes in twentieth-century psychiatry, and the lessons he draws from it are pointed. The parallels he identifies with contemporary gender medicine are deliberate and carefully argued. In each case, he suggests, a professional consensus formed rapidly around claims that lacked an adequate empirical base; each movement recruited the language of trauma and patient liberation; and in each instance the people who suffered most were those already most vulnerable — the young and the psychologically distressed. He situates this pattern within a broader philosophical frame, drawing on Paul Ricoeur's concept of the schools of suspicion — the tradition associated with Marx, Nietzsche and Freud of treating visible reality as a disguise for hidden truths accessible only to the initiated. That intellectual inheritance, he argues, has made medicine peculiarly prone to ideological capture. For European audiences, these observations carry specific weight. Paediatric gender medicine's foundational clinical model originated in the Netherlands, and it was the countries that adopted that model earliest — Sweden, Finland, Denmark — that have since moved most decisively to restrict puberty blockers and cross-sex hormones for minors, citing insufficient evidence. France, Germany and EU institutions are navigating the same questions at different speeds. McHugh's account of how an overvalued belief develops institutional immunity to challenge helps explain why corrections of this kind take as long as they do, and what is required to make them hold. What distinguishes this conversation from a purely historical exercise is McHugh's attention to how reform actually happens: how dissenting clinicians build coalitions, how contrary evidence accumulates until it can no longer be suppressed, and why the inductive, bottom-up approach to medicine his mentor George Thorne instilled in him in the 1950s remains the surest defence against professional capture. For clinicians, researchers and policymakers across Europe now navigating the consequences of decisions made during gender medicine's rapid expansion, that is not a historical question but an immediate one.
