These are just some of the websites, articles, papers, and videos on SP that I managed to find on the internet. Most of the SP material available on the internet is nonsense, of course. What I've chosen to include here, however, is intelligent and compelling material of a reasonably high quality. Some of the articles below are very skeptical and "anti-paranormal" in tone, but nonetheless make for interesting reading. Enjoy.
