So, no raw nerves from me, just a solid argument based on good science.  No wild claims that psychic phenomena cannot be true, but a solid assertion that is as unlikely as a teapot orbiting between Mars and Jupiter.

Like you, Martin, I don't agree with what Jan offers here, not because it isn't scientific, but because of what I have seen of it and the damage it does to people; when I couple that experience with what I believe Christians are taught about it in the Bible, I regard it as not so much something that is out of my comfort zone, but something to be actively avoided.  However, there are large areas of life where science plays little or no part.  For instance, why we believe what we do, and why we trust who we do is rarely adequately explained by scientific models.
