The takeaway

Brief 'prebunking' videos, delivered where teens already are, measurably improved their ability to spot manipulation — at massive scale.

I.
What happened

The situation, the move, the outcome.

Building on the inoculation idea, Google's Jigsaw division and Cambridge researchers made five short videos explaining common manipulation techniques — emotionally loaded language, false dichotomies, scapegoating and more — and ran them as YouTube pre-roll ads. Across seven studies, including a real-world field test with 22,632 viewers, the videos improved people's ability to recognize manipulation by about 5% even amid YouTube's distractions, boosted confidence in spotting it, and led to better sharing decisions — with effects robust across the political spectrum.

II.
The bigger picture

Why it matters beyond one family.

The breakthrough is scale: prebunking can be delivered to millions through the same ad systems that spread misinformation, meeting teens on the platforms they actually use.
