The positive results in parapsychology tend to be like 35% hit rates where chance would give a 25% hit rate. It isn’t really financially feasible for researchers to gather enough data for a p value of 0.000001 (which, quite reasonably is what Randi requires—who wouldn’t take a 5 in 1000 shot at a million bucks?).
Which isn’t to say I think psy is the best explanation for the p= 0.005 results out there, just that no one challenging for the Randi prize doesn’t say much about academic parapsychology.
