Twitter has fact-checked President Donald Trump for the first time. Trump had claimed on Twitter that mail-in ballots would be "substantially fraudulent." Now his two tweets on the topic have been labeled with a link inviting readers to "get the facts about mail-in ballots" and directing them to resources stating that Trump's claims are unsubstantiated. Here are four key takeaways.
On the facts, Twitter is right and Trump is wrong
Trump claims that switching to mail-in ballots is going to lead to substantial levels of election fraud. As Richard Hasen has noted in the Monkey Cage, a blog written by political scientists and hosted by the Washington Post, there is a very strong consensus that this claim is flat-out wrong and that the available evidence shows that there is only a negligible level of mail-in ballot fraud.
Some have speculated that Trump is arguing against mail-in ballots because he believes they will benefit Democrats and hurt Republicans. Again, the political science evidence goes the other way. Writing for the Monkey Cage, Daniel Thompson and his colleagues find that mail-in ballots do not advantage either party, while Enrijeta Shino and her colleagues show that mail-in ballots for younger, minority and first-time voters are more likely to be invalidated.
This isn't a straightforward free-speech issue
Trump has responded to Twitter's action by claiming that "Twitter is completely STIFLING FREE SPEECH." This claim misrepresents the actual situation. Social media platforms are not public utilities. Instead, they are run by private-sector organizations, usually for profit. Under Section 230 of the Communications Decency Act, platform companies have fairly wide discretion either to remove content (if they see fit) or to keep it up. This leads to two contested questions — how they ought to use their discretion, and whether they ought to have it in the first place.
The first of these is the topic of increasingly heated debate. As Tarleton Gillespie discusses in his book on social media moderation, platform companies have always restricted their users' ability to post content, and these restrictions have always reflected value judgments. Increasingly, these value judgments have themselves been contested, by users and groups who want some kinds of speech to be restricted and other users who disagree. Whenever a social media company bans someone like the conspiracy theorist Alex Jones, there are bitter criticisms that free speech is being undermined. Whenever a social media company declines to ban someone like Jones, there are bitter complaints that his false claims are going unchecked.
Social media companies would prefer not to be turned into arbiters of political truth — a responsibility that involves many risks and few opportunities for profit. However, they are increasingly being obliged to craft policies and institutions to deal with controversial content.
What they fear most is the possibility that their decisions will lead to a political counterreaction. Social media companies are not very popular. Many on the left see them as dangerous monopolies, while some on the right see them as self-appointed speech police. Joint efforts by the left and right to curb the power of social media platforms could seriously damage their business model and perhaps even completely undermine it.
Twitter's new policy is a big change, but one that builds on past policy
This is why Twitter's labeling of Trump's tweets as misleading is significant. In the past, Twitter has been extremely reluctant to regulate Trump's speech in any way. While Trump's tweets have frequently been personally derogatory, have propagated conspiracy theories and have otherwise offended against Twitter's terms of service (the contractual rules that bind Twitter's users), Twitter has been reluctant to intervene.
