Searching the Internet for Evidence of Time Travelers

Did they address how they corrected for the fact that, rather than discovering time travellers, their methodology might just discover real psychics?

Although it’s worth noting, their null result means they didn’t find any of those, either.

Rickrolling? THAT’S your idea for finding time travelers?

If I were in on the test protocols, I would filter for precogs by checking context of the anachromeme. A precog will use it in context, as they are picking up cultural resonance from future minds. A time traveller will use it as a flag or a marker, trusting that the phrasing will be noted by their controllers.
