Scientists should admit their covid errors to regain the trust they lost

Public health officials were rightfully dismayed by Trump’s unreliable bombast but the answer isn’t to pretend to be infallible.

  • American trust in them has dropped, given their pandemic mis-calls, but they could earn it back. Their dedication to the pursuit of truth is under watch.

During the covid years, Americans’ trust in scientists fell, according to a Pew poll. In 2019, only 13% of Americans were distrustful enough to say they weren’t confident in scientists to act in the public’s best interest. Now that figure is 27%—despite recent triumphs in astronomy, cancer research, genetics and more. It’s reasonable to assume the problem stems from covid-era public health missteps. Some public health agencies took years to admit what had become obvious: that the virus was airborne. Others suggested precautions like closing playgrounds and beaches whose benefit would have been minimal. Some promoted policies like sustained social isolation that were hard to implement and endure.

Public health researchers and officials seem to think that rebuilding trust is just a matter of clearer, more persuasive communication. That would help, but it’s not enough—they should admit their mistakes.

There has been reluctance. Last week, I attended an international meeting at Boston University on pandemic preparedness, and a panel on communication never got into covid mistakes. When I asked experts afterwards about policies and declarations that look wrong in retrospect, I got a chorus of “We didn’t know"—an unsatisfying answer. Even at the time, scientists should have been clearer when they were basing policies on educated guesses.

Sandro Galea, dean of public health at Boston University, delves into what public health got wrong in his new book, Within Reason: A Liberal Public Health For an Illiberal Time, to be published soon. He tackles the silencing of dissent which led to groupthink and the encroachment of political and personal opinions into science. That led to policies that were not always within reason—restrictions on outdoor behaviour, closed playgrounds and prolonged school closings.

In an interview, Galea told me that the reluctance to talk about such mistakes comes from insecurity—a fear of giving in to the other side, equated here with former US President Donald Trump. Public health officials were rightfully dismayed by Trump’s unreliable bombast. But the answer isn’t to pretend to be infallible.

Even as early as January and February 2020, the US public health community was making unforced errors. Evidence mounted week after week that this disease was wreaking havoc in China and was spreading around the world. Health authorities should have been scrambling to prepare hospitals and nursing homes, to create tests that worked, and to develop a strategy for contact tracing and virus monitoring. They should have warned people of possible closures ahead.

Instead, the US got reassurance from public health officials, including editorials claiming that seasonal flu was a worse threat. New York’s major outbreak in March 2020 created the conditions for a U-turn. As people died despite the lockdowns, we got moralizing about the dangers of going outside, despite reasonable evidence that was not the problem.

Perhaps it’s misguided to expect people to trust scientists when trust in so many institutions has fallen. (Scientists are still more trusted than journalists, by the way.) And yet science works because scientific methods were developed to smooth out the work of fallible humans into a body of reliable and useful knowledge.

The double-blind clinical trial is an ingenious antidote to bias and our human tendency to see what we want rather than what’s really there. That’s why I got the covid vaccine—not because I uncritically trust Anthony Fauci. The same level of evidence didn’t support the implementation of vaccine mandates, and some institutions went beyond reasonable evidence in forcing workers and students at very low risk of severe disease to get second and third booster shots.

This public health excess fed into existing pockets of irrational paranoia, giving new power to gurus on YouTube who proclaimed that the government was covering up deadly vaccine side effects as well as the ‘real’ cure for covid, apart from UFO aliens and plots to take away everyone’s property. Some of those spouting conspiracy theories were scientists (or at least people with the right degrees), which pointed to a flaw in the idea that people should trust the whole profession. Historian Edward Tenner calls them “alt-thorities" and they show up not just on YouTube, but Fox News and the popular Joe Rogan show.

So maybe the best we can hope for is more trust in scientists who appeal to that great body of established knowledge, and who present new knowledge when bolstered with multiple lines of evidence. And we should trust them not necessarily to act in the public interest, but to act in the pursuit of truth. ©bloomberg
