A 2023 study found X's algorithmic feed shifted users’ political views rightward, increasing support for Republicans and Trump, with lasting effects.

A 2023 study of 4,965 U.S. X users found that switching to the platform’s algorithmic "For You" feed shifted political views toward the right, increasing support for Republican-leaning issues, more favorable views of Donald Trump, and pro-Russian attitudes on Ukraine, with lasting effects even after reverting to a chronological feed. The algorithm boosted right-leaning content and political activists' posts while reducing traditional news visibility, and users maintained new follow patterns, highlighting the long-term influence of algorithmic curation on political attitudes and media consumption.
