"The Biggest Scandal Since Lobotomies" - Tavistock Whistleblower Marcus Evans
Marcus Evans spent 45 years inside British psychiatry and sat on the Tavistock's board of governors before resigning in 2019. His wife Sue was the clinic's very first whistleblower, twenty years ago. Drawing on his new book, Evans argues that gender medicine has not merely made errors — it has collapsed as a clinical discipline. For British listeners who lived through the Tavistock years, his account is both a reckoning and a warning about what comes next.
Marcus Evans brings to this conversation something no outside commentator can: forty-five years inside British psychiatry, including a seat on the board of governors at the Tavistock and Portman NHS Trust — an institution that, for decades, sat at the centre of Britain's approach to childhood gender distress. He resigned that governorship in 2019 after months of pressing executives over internal concerns that were not being adequately addressed. His wife, Sue Evans, had raised the alarm fourteen years earlier, making her the clinic's first known whistleblower. That family history alone gives this episode a weight that few conversations about Tavistock can match. Evans traces a damning timeline. An internal report from 2006, he argues, had already identified the very failings that the Cass Review would eventually confirm nearly two decades later. The fact that those findings were buried — and that children continued to receive experimental medical interventions during the intervening years — is, in his view, what makes this not merely a policy failure but a scandal. He reaches for the strongest comparison in modern medical history: the lobotomies performed in the mid-twentieth century, procedures once presented as pioneering and progressive before the full harm became undeniable. The clinical argument at the heart of Evans's new book, Identity and the Foundational Myth, centres on the concept of the overvalued belief. He draws a direct parallel with anorexia: a therapist who accepted a patient's conviction that food is poisonous would not be offering treatment — they would be colluding with the distress. Evans argues that gender medicine, in affirming a fixed cross-sex identity without therapeutic interrogation, has done precisely that. He describes therapists who have privately admitted that they recognise the collusion but feel unable to resist the institutional and cultural pressure to go along with it. Evans is particularly sharp on the new NHS puberty-blocker trial, which some have held up as evidence that Britain has adopted a more cautious, evidence-led approach since the Tavistock's closure. He is unconvinced. Two years of follow-up data, he argues, is wholly inadequate for interventions that will shape a child's entire reproductive and hormonal future. The meaningful questions — about fertility, about regret, about identity in middle age — simply cannot be answered on that timescale. What emerges from this conversation is a picture of an institution that failed its patients not through ignorance alone but through a collective unwillingness to apply the ordinary standards of clinical medicine. As England builds its replacement regional gender services, Evans's account is a reminder that the culture which shaped the Tavistock did not disappear when the clinic closed. The Cass Review gave Britain a diagnosis. Evans, speaking from inside the institution itself, explains how the patient ended up on the table.
