Oops, didn't answer the question.
Is there empirical evidence for it?
Well, I myself haven't delved extensively into it, but I'd say that it hasn't gone too far. I'm not saying that empirical evidence for it CANNOT exist. I think people are just afraid to touch it for fear that they'll lose credibility as social scientists. So the field doesn't get much research done, and it stays stigmatized. I've looked for different places that have courses in parapsyc, and there are very few that teach it. One of the reasons why is what I've already said above just now, and another reason (which I've also already said, but earlier) is probably because there's not a lot of work for parapsychologists. I guess they figure, "Why teach it, then?"
=================
Edit: I have another hypothesis about why parapsyc might not be taken seriously.
First of all, I think that there is a possibility that there is such a thing as psi phenomenon. Under the assumption that it exists [I won't say it definitely does or does not, for the purposes of being objective], I believe that it is not consistent. So while some people have an ability some of the time, nobody has it all of the time. When the person with the alleged psi abilities screws up, the skeptics jump all over them, saying that this is PROOF that the psi phenomenon DOES NOT EXIST AT ALL. Fatalistic, huh.
