Every Monday night millions of Americans tune into Medium, NBC's new hit drama featuring Allison DuBois, an ordinary woman who helps police solve baffling crimes through her ability to communicate with the dead. What most don't know is that this fictional character is based on a true-life medium named Allison DuBois, who is a consultant to the show. For the past four years, DuBois has been the subject of rigorous scientific experiments conducted at the University of Arizona by Harvard-trained psychologist Gary Schwartz. The Truth about Medium chronicles many of those experiments as well as the real-life cases Allison has worked on and reveals hard laboratory evidence that psychic ability and mediumship are real.
