For 25 years, Richard Horton, hard-left polemicist, has been editor-in-chief of the Lancet, the stately old Florence Nightingale of medical journals. Yet despite a string of political scandals during his tenure, it remains second in influence only to the New England Journal of Medicine (NEJM). Horton’s causes célèbres include publishing an inflated Iraq War death toll, a letter on Gaza from pro-Hamas doctors and calling for physicians to join Extinction Rebellion.
