W hen major decisions must be made amid high scientific uncertainty, as is the case with Covid-19, we can’t afford to silence or demonize professional colleagues with heterodox views. Even worse, we can’t allow questions of science, medicine, and public health to become captives of tribalized politics. Today, more than ever, we need vigorous academic debate.
To be clear, Americans have no obligation to take every scientist’s idea seriously. Misinformation about Covid-19 is abundant. From snake-oil cures to conspiracy theories about the origin of SARS-CoV-2, the virus that causes the disease, the internet is awash with baseless, often harmful ideas. We denounce these: Some ideas and people can and should be dismissed.
At the same time, we are concerned by a chilling attitude among some scholars and academics, who are wrongly ascribing legitimate disagreements about Covid-19 to ignorance or to questionable political or other motivations.
A case in point involves the response to John Ioannidis, a professor of medicine at Stanford University, who was thrust into the spotlight after writing a provocative article in STAT on Covid-19. He argued in mid-March that we didn’t have enough information on the prevalence of Covid-19 and the consequences of the infection on a population basis to justify the most extreme lockdown measures which, he hypothesized, could have dangerous consequences of their own.
