(p. A23) If it turns out that the Covid pandemic was caused by a leak from a lab in Wuhan, China, it will rank among the greatest scientific scandals in history: dangerous research, possibly involving ethically dubious techniques that make viruses more dangerous, carried out in a poorly safeguarded facility, thuggishly covered up by a regime more interested in propaganda than human life, catastrophic for the entire world.
But this possible scandal, which is as yet unproved, obscures an actual scandal, which remains to be digested.
I mean the long refusal by too many media gatekeepers (social as well as mainstream) to take the lab-leak theory seriously. The reasons for this — rank partisanship and credulous reporting — and the methods by which it was enforced — censorship and vilification — are reminders that sometimes the most destructive enemies of science can be those who claim to speak in its name.
. . .
Was it smart for science reporters to accept the authority of a February 2020 letter, signed by 27 scientists and published in The Lancet, feverishly insisting on the “natural origin” of Covid? Not if those reporters had probed the ties between the letter’s lead author and the Wuhan lab (a fact, as the science writer Nicholas Wade points out in a landmark essay in The Bulletin of the Atomic Scientists, that has been public knowledge for months).
Was it wise to suppose that the World Health Organization, which has served as a mouthpiece for Chinese regime propaganda, should be an authority on what counted as Covid “misinformation” by Facebook, which in February  banned the lab-leak theory from its platform? Not if the aim of companies like Facebook is to bring the world closer together, as opposed to laundering Chinese government disinformation while modeling its illiberal methods.
. . .
Yet the lab-leak theory, whether or not it turns out to be right, was always credible. Even if Tom Cotton believed it. Even if the scientific “consensus” disputed it. Even if bigots — who rarely need a pretext — drew bigoted conclusions from it.
Good journalism, like good science, should follow evidence, not narratives. It should pay as much heed to intelligent gadflies as it does to eminent authorities. And it should never treat honest disagreement as moral heresy.
Anyone wondering why so many people have become so hostile to the pronouncements of public-health officials and science journalists should draw the appropriate conclusion from this story. When lecturing the public about the dangers of misinformation, it’s best not to peddle it yourself.
