I wish they would try the presentiment experiment with the same setup - my guess is that they would see a strong signal.

'Deciding' which button to press seems a pretty artificial task. Coincidentally, I had my eyes tested recently, and one of the gadgets that they use over here is a thing a bit like a rather boring video game. The idea is to measure your field of view. You track a red dot with one eye and then press a button n times if you see n green dots. n ranges from 0-4. The decision time is quite short to avoid the eya simply scanning the field of view - so it might be fun to run that inside the scanner. Again, presentiment might show up.

The idea that people do not have free will has always seemed to me utterly preposterous - far more so than presentiment or Ψ!
