real
AI or Not, a study tool for how well people actually spot AI-generated video.

The definition
What everyone assumes: People can tell when a video is AI-generated. Corrected to: Show clip pairs, force a choice about which one is synthetic, and aggregate the votes into a preference report. Confidence stops counting. The vote is the data.
Where it broke. That is a self-report, not a measurement. Asking someone how good they are at spotting fakes tests how confident they feel.
