Summary

A study found that TikTok’s recommendation algorithm favored Republican-leaning content during the 2024 U.S. presidential race.

TikTok, with over a billion active users worldwide, has become a key source of news, particularly for younger audiences.

Using 323 simulated accounts, researchers discovered that Republican-leaning users received 11.8% more aligned content than Democratic-leaning users, who were exposed to more opposing viewpoints.

The bias was largely driven by negative partisanship, with more anti-Democratic content recommended.
