Hmm, I can't get the full text article, and have never heard of Radin, so I'll reserve judgement, but I have to say, I'm very, very, skeptical.

Even IF psi has been demonstrated in an MRI, we have no way of knowing whether the aliens have a nervous system that is enough like ours to receive and respond to our 'psi signals.' We also don't know how psi signals might propagate, how quickly they travel, or how precise we can get it (a few meters is one thing, tens of thousands of light years is another).

In contrast, if you can count above 2, you have integers.
