The First Amendment hasn’t kept public officials from calling upon Facebook, YouTube, Twitter, and other tech platforms to restrict false or misleading claims about vaccination and other COVID-related issues. The White House has urged tech companies to censor individuals engaged in protected speech. Senator Amy Klobuchar introduced legislation in hopes of pressuring social-media companies to do more “to prevent the spread of deadly vaccine misinformation.” And the government can apply pressure on private speech in other ways: The Department of Homeland Security, for example, is characterizing misinformation as a terrorism threat. All of these efforts reflect a judgment that, at least on pandemic matters, the liberal approach to dissent has greater costs than benefits.
But that judgment is mistaken. During past crises, even wars, the case for liberal speech norms remained so strong that Americans look back on departures from them with regret. Likewise, I can think of at least four reasons why neither government officials nor corporate bosses should try to protect the public by newly restricting the expression of ideas, even during a pandemic.
