First Amendment Metaphors: The Death of the “Marketplace of Ideas” and the Rise of the Post-Truth “Free Flow of Information”

Abstract

As cognitive linguists George Lakoff and Mark Johnson have shown, metaphors are words “we live by.” In law, they are words we govern by. The “marketplace of ideas,” introduced into the jurisprudential imagination just over a century ago by Justice Holmes dissenting in Abrams v. United States, persists as the central organizing metaphor for how judges, scholars, and the public understand the freedom of expression. It envisions a speech ecosystem where competition among ideas, refereed by a responsible press, results in truth winning out. But the marketplace metaphor is a relic. Today’s expressive ecosystem dramatically departs from the metaphor’s core assumptions, marked by information overload and replete with misinformation and lies proliferated by speech platforms unable or unwilling to act as “arbiters of truth.” These dynamics are better described by another First Amendment metaphor, “the free flow of information,” which has operated as a stealth metaphor: obscured by the ubiquitous marketplace metaphor, it has done enormous work within the doctrine without much critical notice. The metaphor’s logic privileges information over ideas, prioritizes content quantity over quality, and removes accountability from the system of free expression. In the end, truth is the casualty.
