Some Background

Do you consider yourself psychic? Have you had experiences where you just know who is calling before you answer the phone, or even before it rings?  If so we'd like to invite you to participate in an experiment that is designed to verify this effect.  What's more, you'll be taking part in a scientific experiment to distinguish between several different models that might make paranormal (PSI) phenomena possible in the first place.

The study of PSI phenomena has been going on for more than one hundred years now.  Recent work and thought has focussed on several different mechanisms to explain how such effects might be possible.  These include retrocausation (knowledge of an actual future); clairvoyance (knowledge of present reality that is hidden from the viewer); and telepathy (actually a special case of clairvoyance, the hidden reality being the thoughts of another person).  The PSI games that make up the present experment use a new protocol that can distinguish between retrocausation and clairvoyance in tests that only involve a single subject (yourself) while incorporating the strengths of previous tests that required multiple participants.  We hope that you enjoy playing these games.  We also hope that the new protocol will allow us for the first time to unambiguously distinguish between the two explanations. 

Several previous studies have obtained positive effects with very high significance (that is, a low probability that the outcome was due to chance) using various protocols.  Two of these provide a good background for the present work.  They are the study of "telephone telepathy" by Rupert Sheldrake, and studies of an "anomalous anticipatory effect" or presentiment by Dick Bierman and Dean Radin.  The extremely high statistical significance shown by Sheldrake's experiments is most enticing; as is the clearly anomalous "presponse" effect shown by those of Bierman and Radin.  We have incorporated into our experiments what we believe are the best aspects of both of these previous studies.  If this interests you, please consider participating in our study.
