Social media has political divides, but some feeds are more polarized than others

The 2024 presidential election cycle in the U.S. has been dubbed the influencer election, because it was the moment when political voices on social media received an unprecedented amount of amplification. Moving forward, strategists on both sides of the aisle are trying to maximize social media’s potential as a political tool, but that process comes with some complications.

One of those complex wrinkles came under the microscope in a study published in the journal Nature. Researchers set up 323 “sock puppet” accounts on TikTok to measure the political polarization of the For You Page, and they found some apparent disparities between right-leaning and left-leaning feeds.

It has long been understood that the political leanings of social media users have a profound effect on the algorithmic recommendations those users receive. To put it simply, an avowed leftie is not going to see the latest report from The Daily Caller, and right-wingers will not be served updates from Jacobin.

The Nature study, however, showed that siloed social media feeds aren’t as straightforward as they might seem. The experimental accounts were split up, with some trending toward left-wing recommendations while others moved toward the right. All told, the sock puppets received more than 280,000 recommendations over 27 weeks during the 2024 U.S. presidential election cycle.

The Republican accounts were 11.5% more likely than Democrat accounts to receive recommendations that aligned with their political beliefs. It follows, then, that Democrat accounts were 7.5% more likely to see content that crossed party lines.

The key difference involves content that criticizes a particular party. Democratic accounts are sometimes served content that can be defined as anti-Democrat, but Republican accounts rarely see anti-Republican content. And in a survey attached to the study, Republican respondents were more likely to use words like “positive,” “optimistic,” and “agreeable” when describing the content they see on the For You Page.

The researchers argued that the uneven nature of algorithmic recommendations presents issues for regulators. “The contrast highlights both the urgency and difficulty of developing governance frameworks for partisan content exposure asymmetries on platforms, particularly when those platforms achieve monopolistic scale in highly polarized contexts,” reads the report.

But there’s another group that must also pay attention to these results: Political strategists. After Republicans dominated digital discourse in 2024 by linking President Trump’s “big man” persona to creator culture, Democrats have made it clear that they intend to copy that strategy in 2026. In this case, however, mimicry is easier said than done. If left-wing feeds are more likely to be self-critical than right-wing feeds, then firms like AND Media may need to adjust their messaging to address progressive frustrations related to Democratic policy.
