TikTok algorithm pushed anti-Democratic videos during election

The research shows TikTok's algorithm didn't just build echo chambers, but actively cross-pollinated conservative narratives to liberal users.

• –Bot accounts programmed to engage with Democratic content received 7.5% more anti-Democrat videos than conservative accounts received opposing views.
• –The algorithm aggressively clustered sensitive topics, serving Democrats videos about immigration and crime while feeding Republicans content on abortion.
• –A follow-up survey of real TikTok users confirmed the experimental data, showing Republicans were significantly more likely to see positive content aligning with their views.
• –While TikTok dismissed the methodology, the study provides hard data on how opaque recommendation engines might have influenced the 2024 youth vote shift.
