Recent academic studies suggest that social media is indeed corrosive to trust in governments, news media, and people and institutions in general. A working paper that offers the most comprehensive review of the research, led by the social scientists Philipp Lorenz-Spreen and Lisa Oswald, concludes that “the large majority of reported associations between digital media use and trust appear to be detrimental for democracy.” The literature is complex—some studies show benefits, particularly in less developed democracies—but the review found that, on balance, social media amplifies political polarization; foments populism, especially right-wing populism; and is associated with the spread of misinformation.

When people lose trust in institutions, they lose trust in the stories told by those institutions. That’s particularly true of the institutions entrusted with the education of children. History curricula have often caused political controversy, but Facebook and Twitter make it possible for parents to become outraged every day over a new snippet from their children’s history lessons––and math lessons and literature selections, and any new pedagogical shifts anywhere in the country. The motives of teachers and administrators come into question, and overreaching laws or curricular reforms sometimes follow, dumbing down education and reducing trust in it further. One result is that young people educated in the post-Babel era are less likely to arrive at a coherent story of who we are as a people, and less likely to share any such story with those who attended different schools or who were educated in a different decade.

The former CIA analyst Martin Gurri predicted these fracturing effects in his 2014 book, The Revolt of the Public. Gurri’s analysis focused on the authority-subverting effects of information’s exponential growth, beginning with the internet in the 1990s. Writing nearly a decade ago, Gurri could already see the power of social media as a universal solvent, breaking down bonds and weakening institutions everywhere it reached. He noted that distributed networks “can protest and overthrow, but never govern.” He described the nihilism of the many protest movements of 2011 that organized mostly online and that, like Occupy Wall Street, demanded the destruction of existing institutions without offering an alternative vision of the future or an organization that could bring it about.
