Now the government is out to quash this plague of poor decision making. In June, when Kennedy sacked all 17 members of the nation’s top vaccine-advisory panel, a Health Department spokesperson said that it was a remedy for “vaccine groupthink.” Upcoming changes to the U.S. dietary guidelines have been cast as a way of fighting groupthink too. Both Bhattacharya and the MAHA leader Calley Means have decried the groupthink infestation in our scientific institutions. And two months before his nomination to be FDA commissioner, Marty Makary published an entire book about the perils of medical groupthink. Health Department Press Secretary Emily Hilliard told me via email that Kennedy is “confronting groupthink by rebuilding a culture where scientists can question, debate, and follow evidence freely so that truth—not conformity—drives public health decisions.” The epidemic of consensus, as he sees it, must be stopped.
