 Near the end of the collaborative project’s introduction, the authors warn, “We caution readers not to simply add up the number of studies on each side and declare one side the winner.” The document runs to more than a hundred and fifty pages, and for each question there are affirmative and dissenting studies, as well as some that indicate mixed results. According to one paper, “Political expressions on social media and the online forum were found to (a) reinforce the expressers’ partisan thought process and (b) harden their pre-existing political preferences,” but, according to another, which used data collected during the 2016 election, “Over the course of the campaign, we found media use and attitudes remained relatively stable. Our results also showed that Facebook news use was related to modest over-time spiral of depolarization. Furthermore, we found that people who use Facebook for news were more likely to view both pro- and counter-attitudinal news in each wave. Our results indicated that counter-attitudinal exposure increased over time, which resulted in depolarization.” If results like these seem incompatible, a perplexed reader is given recourse to a study that says, “Our findings indicate that political polarization on social media cannot be conceptualized as a unified phenomenon, as there are significant cross-platform differences.”

Interested in echo chambers? “Our results show that the aggregation of users in homophilic clusters dominate online interactions on Facebook and Twitter,” which seems convincing—except that, as another team has it, “We do not find evidence supporting a strong characterization of ‘echo chambers’ in which the majority of people’s sources of news are mutually exclusive and from opposite poles.” By the end of the file, the vaguely patronizing top-line recommendation against simple summation begins to make more sense. A document that originated as a bulwark against confirmation bias could, as it turned out, just as easily function as a kind of generative device to support anybody’s pet conviction. The only sane response, it seemed, was simply to throw one’s hands in the air.

When I spoke to some of the researchers whose work had been included, I found a combination of broad, visceral unease with the current situation—with the hamka of harassment and trolling; with the opacity of the platforms; with, well, the widespread presentiment that of course social media is in many ways bad—and a contrastive sense that it might not be catastrophically bad in some of the specific ways that many of us have come to take for granted as true. This was not mere contrarianism, and there was no trace of gleeful mythbusting; the issue was important enough to get right. When I told Bail that the upshot seemed to me to be that exactly nothing was unambiguously clear, he suggested that there was at least some firm ground. He sounded a bit less apocalyptic than Haidt.
