Rudism,
Perhaps you are beginning to see my point - attempts at total rigour stifle any experiment - PSI or otherwise. I would certainly be convinced if the various trials were a 50/50 mixture of the traditional totally random type and trials with a guaranteed number of events, and the results for the two sets of data were broadly similar.
I must admit, having read all the above, I am becoming cautiously optimistic that presentiment is real - because if it is, it should (eventually!) give us some fascinating new science.
