We’ve long known that medical companies of various sorts have sought to “buy” research which suits their respective agendas. As we’ve reported, pharmaceutical companies have tried (with success) to influence journals and experts via various means. One particularly egregious example we cited was with a group of scientists focused on influencing the official data on the efficacy of painkillers.
Of course companies try to buy practitioners as well as researchers. They hope the practitioners they have bought will persuade other practitioners who may not know about the payments.
