X algorithm amplified right-wing and extreme content in the UK

Investigations and academic research documented that X’s recommendation/feed algorithm systematically promoted right‑wing and, in many cases, extreme content to UK users. Sky News’ controlled experiment (reported via AIAAIC and GIJN) found a majority share of political posts shown to test accounts came from right‑wing or extreme accounts, and a 2026 peer‑reviewed Nature study found X’s algorithm promotes conservative content relative to a chronological feed. Multiple independent sources report these findings publicly.

The events drew public criticism and media coverage but no public regulatory enforcement action is documented in the cited sources.
