Jennifer Nuzzo is a health expert who has become nationally prominent during the pandemic. She is the leading epidemiologist for Johns Hopkins University’s much-cited data collection on Covid-19 testing. She is active on Twitter and quoted frequently in the media. She can explain complex ideas in clear terms, and she has often been prophetic about Covid.

Nonetheless, she took to Twitter last May to criticize herself. She had expected Texas’ ending of its mask mandate to lead to a surge in cases, and it had not:


Nuzzo’s small exercise in self accountability highlighted the inherent unpredictability of this virus. (Masks do reduce its spread, but the effect can be too modest to be visible across an entire community or state.) Her tweet made a larger point, too: People with a public platform should be willing to admit when they’re wrong.

There is no shame in being wrong at times. Everybody is, including knowledgeable experts. The world is a messy, uncertain place. The only way to be right all the time is to be silent or say nothing interesting.

The problem isn’t that people make mistakes; it’s that so few are willing to admit it.

Many experts instead post aggrandizing praise of themselves on social media. They claim that each new development — be it on Covid, the economy, politics or foreign affairs — justifies what they’ve been saying all along. They don’t grapple with the weak points in their arguments and hope nobody notices their past incorrect predictions.

We journalists commit the same sins. More than a decade ago, in an effort to do better, David Weigel of Slate (and now of The Washington Post) introduced a concept he called “pundit accountability.” It describes articles in which journalists highlight their own mistakes — and not small factual errors, which often get corrected, but errors of analysis, which don’t.
