One-line summary: Publisher of the crowdsourced YouTube Regrets study — the fetched independent counterweight to YouTube’s own “we don’t steer toward extremes” claim.
What it is
A nonprofit that ran RegretsReporter, a browser extension used to collect user-flagged “YouTube Regrets.” The fetched findings page covers 37,380 volunteers and 3,362 reports (1,662 reporting volunteers, 91 countries, July 2020–May 2021). From 2026-08-21-autoresearch-user-owned-interest-graph-youtube-recs.
Why it matters to interest-graph-recs
Mozilla measures user-defined regret, including off-topic and harmful recs — closer to “rabbit hole” than YouTube’s classifier-demoted “borderline” bucket.
Key facts
- 71% of regret reports were recommended videos; recommended videos were 40% more likely to be regretted than searched-for videos (via 2026-08-21-autoresearch-user-owned-interest-graph-youtube-recs).
- Regret rate 60% higher in countries where English is not the primary language (17.5 vs 11.0 per 10,000 videos; CIs on the Mozilla page).
- Asks YouTube to give people meaningful control over how their data is used for recommendations, including opt-out of personalized recs.
- “Regret” is intentionally not a YouTube policy class.
