Fox News reporters have done some solid reporting. And the network has recently given some screen time to medical and public health professionals. But Fox News does not clearly distinguish between the authority that should accrue to trained experts, on the one hand, and the authority viewers grant to pundits and politicians for reasons of ideological loyalty. There is a tendency to accept (or reject) them all indiscriminately, for after all, they are talking heads who appear on Fox News, a trusted source of news. When the statements of knowledgeable experts are surrounded by false claims made by pundits and politicians, including President Trump — claims that are not rebutted by knowledgeable people in real time — the overall effect is to mislead a vulnerable public about risks and harms. Misinformation furthers the reach and the dangers of the pandemic. For example, the day after Tucker Carlson touted a flimsy French study on the use of two drugs to treat COVID-19, President Trump touted “very, very encouraging early results” from those drugs, and promoted a third as a possible “game changer.”

The basic purpose of news organizations is to discover and tell the truth. This is especially necessary, and obvious, amid a public health crisis. Television bears a particular responsibility because even more millions than usual look there for reliable information.

Inexcusably, Fox News has violated elementary canons of journalism. In so doing, it has contributed to the spread of a grave pandemic. Urgently, therefore, in the name of both good journalism and public health, we call upon you to help protect the lives of all Americans — including your elderly viewers — by ensuring that the information you deliver is based on scientific facts.
