In March 2004, Monica Garnsey, the producer-director of a Discovery Channel documentary on Natasha, asked the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP) to scientifically test the young woman’s claims for the program. Because Natasha’s paranormal claims involved medical diagnoses, I was asked to join CSICOP fellows Ray Hyman and Richard Wiseman in designing an appropriate preliminary test, to see if the medical psychic’s abilities warranted further study. (Hyman’s accompanying article, “Testing Natasha,” is the report of those tests.)
