Surgical tech here. This shit is prevalent at every level of every job. The last few years have taught us not to automatically respect the title “doctor” - they can be extremely knowledgeable in the context of their field, but still a fucking dumbass in other areas. This is true of nurses, techs, admins, you name it.
Generally you can trust what your orthopedic surgeon has to say about bones, but the second he starts ranting about epidemiology, safest assumption is that he did his ‘research’ on truth social and fox.
