Key figures:
- Sample size: 715 active U.S. X users
- Study period: September‑October 2024
- Correlation between amplified content and self‑stated values: -0.229 for Democrats, -0.041 for Republicans, overall -0.150
- Publication: Proceedings of the National Academy of Sciences (PNAS), Monday (Oct 2024)
- Algorithm examined: X’s “For You” feed
Context
Researchers from MIT, University of Michigan, Johns Hopkins, Stanford and Yale installed a browser extension to capture participants’ “For You” and Following feeds. They measured how often the algorithm surfaced posts that conflicted with users’ explicitly stated political values. A negative correlation indicates that the algorithm preferentially amplifies content misaligned with those values. The effect was strongest among Democrats (‑0.229) and weak among Republicans (‑0.041). Posts from accounts users chose to follow remained largely aligned with their values.
Bottom Line
The study suggests X’s recommendation engine may unintentionally promote “ragebait” that opposes users’ declared preferences, especially for Democratic users. While the finding does not directly affect crypto prices, it could influence broader sentiment toward platform governance and content moderation, potentially prompting regulatory scrutiny or changes to algorithmic transparency. Investors should monitor any subsequent policy shifts at X, as they may affect advertising revenue and user engagement metrics.
