In no way do I think that the parapsychologists have good hypotheses or reasonable claims. I also am a firm adherent to the ethos: Extraordinary claims must have extraordinary proofs. However to state the following:

one in which the null hypothesis is always true.

is making a bold statement about your level of knowledge. You are going so far as to say that there is no possible way that there are hypotheses which have yet to be described which could be understood through the methodology of this particular subgroup. This exercise seems to me to be rejecting these studies intuitively,(without study) just from the ad hominem approach to rejection - well they are parapsychologists therefore they are wrong. If they are wrong, then proper analysis would indicate that, would it not?

I have never seen a parapsychology study, so I will go look for one. However does every single study have massive flaws in it?

Damien Broderick's Outside the Gates of Science summarizes a number of parapsychology studies, noting that several of the studies do indeed seem quite solid. It doesn't come to any definite conclusion over whether psi phenomena are actually real or if there's just something wrong with our statistical techniques, but it does seem like there might be enough to warrant more detailed study. See also e.g. Ben Goertzel's review of the book.
