But my point was that I *have* made the effort to read and investigate
parapsychological claims, even to the extent of what borders on what
we agree is obvious "crap". This in response to your statements here:

Damien, when I've said I see "little or no evidence" for psi, it
doesn't follow that I believe I can prove that it's false or prove
that it doesn't exist. I tried to make it clear that my position on
psi is based on relatively probability mass, being a necessarily
subjective, but willing assessor of the evidence before me.

With the links you provided, I started with the page by Utts and
Josephson at http://anson.ucdavis.edu/%7Eutts/azpsi.html:
"In one type of experiment, a "target" photograph or video segment is
randomly chosen out of a set of four possibilities. A "sender"
attempts to transmit it mentally and a "receiver" is then asked to
provide an account either verbally or in writing of what she imagines
it might be. She is then shown the four possibilities, and selects the
one she thinks best matches her perception. By chance alone, a correct
match is expected on average one time in four, whereas the experiments
typically show the considerably higher success rate of around one in
These are wonderfully significant results, published since 1996,
backed by the prestige of Brian Josephson! Why in the last 10+ years
has this not been reproduced to the satisfaction of the scientific
community? I will say that my own impression is that Ms. Utts is
quite enthusiastic about promoting this field (elsewhere she explains
that it has received only two months of resources, proportionate to a
century for standard psychology.) I feel compelled to wonder at this
point whether this isn't an (unintentional) example of cherry picking
I'm looking forward to reading more of the references and will get back to you.
