Yes, that is some truly wretched writing about some very interesting phenomena. In some respects it's reminiscent of the article about the Placebo effect becoming stronger that was posted the other day. We have lots of evidence, but the organizing theories are all much more fuzzy than they ought to be.

It's very clear that our beliefs about ourselves do influence our bodies. But the mechanisms are obscure, and most of the experiments that could shed some light on the topic are not feasible from an ethical standpoint[1] and most of the explanations are waiting on a better definition of consciousness.

1. Could you get a an ethics board to approve an experiment in which you told a random group of people that they had an incurable and fatal form of cancer that would kill them in a year, just so that you could observe how many of them died of the fiction?

I find that this is the case with most articles posted on alternet.org.
