In the free marketplace of ideas, true ideas are supposed to compete with false ones until the truth wins -- at least according to a leading rationale for free speech. But what if the rise of fake news shows that, under current conditions, truth may not defeat falsehood in the market? That would start to make free speech look a whole lot less appealing.
The rise of fake news therefore poses a serious challenge to our basic ideas about the First Amendment. Much of the debate in recent weeks has focused on social media and search engines. But whether the market for ideas is failing is more fundamental than whether Facebook or Google can be blamed for algorithms that promote and spread false stories.
