Social Media Effects: Hijacking Democracy and Civility in Civic Engagement

Perceived as an equalizing force for disenfranchised individuals without a voice, the importance of social networks as agents of change cannot be ignored. However, in some societies, social networks have evolved into a platform for fake news and propaganda, empowering disruptive voices, ideologies, and messages. Social networks such as Twitter, Facebook, and Google hold the potential to alter civic engagement, thus essentially hijacking democracy, by influencing individuals toward a particular way of thinking.

Shifts in U.S. Social Media Use, 2020–2024: Decline, Fragmentation, and Enduring Polarization

Using nationally representative data from the 2020 and 2024 American National Election Studies (ANES), this paper describes how U.S. social media use has shifted across platforms, demographics, and politics. Overall platform reach declined, driven by growth in the share of Americans — especially the youngest and oldest cohorts — who report using no social media. Visiting and posting activity on Twitter/X and Facebook have fallen by nearly 50% since 2020, with the decline on Twitter/X driven primarily by reduced participation among Democratic users. While Facebook, YouTube, and Twitter/X lost ground, TikTok and Reddit grew modestly, consistent with a more fragmented digital public sphere. Platform audiences aged and became slightly more educated and racially diverse. Politically, most platforms shifted toward Republican users while remaining, on balance, Democratic-leaning. Twitter/X experienced the largest change: among posters, the partisan balance swung over 70 percentage points from Democrats to Republicans. Across platforms, political posting remains closely tied to affective polarization, as the most partisan respondents are also the most active. As casual users disengage while polarized partisans remain vocal, online discourse becomes narrower and more ideologically extreme.

Note: This was originally published as a LinkedIn post on November 11, 2025. I need to make a painful confession: somehow, LinkedIn has become an important social network to me. This isn’t necessarily due to LinkedIn’s sparkling competence, of course. To the contrary, LinkedIn is the Gerald Ford of social networks: the normal one that was left standing as the Richard Nixons and the Spiro Agnews of social media imploded around them. As with Gerald Ford, with LinkedIn we know that we’re getting something a bit clumsy and boring, but (as with post-Watergate America!), we’re also getting something that isn’t totally crooked — and that’s actually a bit of a relief.

Web Browsers, AI, and the Politics of Media Power

The left keeps building media strategies on top of platforms built to undermine them. As browsers are rebuilt for mass surveillance and manipulation, the systems that decide what people see and who gets heard are being rewritten without us. Control over the browser is control over political reality.
