Like ThreadKiller, I've tried to stay away from the R&S forum for a while. I'm just concerned that showing disbelief can make some uncomfortable, and I'd hate to lose friends for speaking my mind. I know most of you are strong enough not to be swayed by anything I'd post, so I hope this post and link aren't taken as condescension.
I also feel that intercessory prayer doesn't work (except as a calmer ). My mother (Roman Catholic) believes.
The second link that Jimi provided is the best scientific study I've read on the subject. I got the impression it was done by people who believed in IP and wanted to show it really worked. Unfortunately, it seems that if people knew you were praying for them, they did even worse than expected. Otherwise, prayer had no effect.
One site that I think is interesting on this subject is "Why Won't God Heal Amputees?"

I had someone ask recently if I was boycotting Forumosa because I haven't posted for a while.

No boycott; I've just been busy with other stuff.
