"The Biggest Scandal Since Lobotomies" - Tavistock Whistleblower Marcus Evans

27 November 2025

With Marcus Evans

Marcus Evans spent 45 years in psychiatry before resigning as a Tavistock governor in 2019, after his wife Sue had already blown the whistle on the clinic's gender service fourteen years earlier. Joined by Stella O'Malley and Mia Hughes, he argues that gender medicine represents the gravest collapse of clinical ethics since the lobotomy era. For European clinicians and policymakers — particularly in countries that built or adopted the protocols Tavistock scaled — his psychoanalytic account of how an institution loses its capacity for honest self-correction is both a case study and a warning.

Marcus Evans is not a peripheral figure in British psychiatry. With 45 years in the field, he served as Associate Clinical Director of the Adult Department at the Tavistock and Portman NHS Trust — the clinic whose approach to gender-distressed young people became a template adopted across the Western world, including in several EU member states. He resigned as a Tavistock governor in 2019 after six months of attempting to force an internal reckoning, building on years in which his wife Sue had been the clinic's first whistleblower in 2005. That those warnings went unheeded for so long is, Evans argues, itself part of the scandal. The lobotomy parallel Evans draws is not hyperbole. Lobotomies were mainstream medicine before the evidence of harm became undeniable; they were endorsed by leading institutions and awarded a Nobel Prize before the damage could no longer be suppressed. Evans sees a structural parallel in gender medicine — a treatment regime that expanded rapidly, was institutionally insulated from scrutiny, and made dissenting clinicians feel professionally unsafe. In conversation with Stella O'Malley and Mia Hughes, he describes how therapists fell into what he calls dishonest collusion with patients: not through malice, but because the clinical culture had been so thoroughly reshaped that honest inquiry felt indistinguishable from cruelty. The anorexia analogy Evans develops will resonate with European clinicians trained in psychodynamic traditions. A therapist working with anorexia does not validate a patient's belief that food is poisonous; the task is to understand what sustains that belief. Evans argues that gender dysphoria demands the same analytical attention, but that the field instead institutionalised affirmation — making the patient's self-description simultaneously the diagnosis and the treatment plan. He frames this through the concept of overvalued belief: a conviction held with such intensity that it becomes resistant to ordinary therapeutic inquiry, ultimately consuming not just individuals but entire clinical departments and the professional bodies meant to oversee them. Particularly relevant for those tracking EU-level policy is Evans's account of a 2006 internal report — filed and effectively buried — that anticipated virtually every finding the Cass Review would publish nearly two decades later. He reconstructs a whistleblower timeline stretching from 2005 to 2019, four separate moments at which corrective action could have been taken. He is equally direct about the new puberty-blocker trial now under way in the UK: two years of follow-up, he argues, is wholly insufficient to understand the consequences of interventions whose effects on development may only become apparent in midlife. For the Netherlands, Sweden, Finland, and other EU countries that built, exported, or adopted gender-affirmation protocols, this account carries specific weight. The Dutch protocol of the 1990s was the global model; Tavistock scaled it. Evans's analysis of how clinical ethics erode inside an institution — step by step, without any single dramatic decision — gives European clinicians and policymakers a language for examining their own systems. His new book, Identity and the Foundational Myth, provides the psychoanalytic underpinning for what he states here with unusual directness: that what presents as a gender problem is, in almost every case, a developmental one, and that treating it otherwise has caused harm on a scale that will take a generation to fully measure.
