Tart was the holder of the Bigelow Chair of Consciousness Studies at the University of Nevada in Las Vegas and has served as a visiting professor in East-West Psychology at the California Institute of Integral Studies, as an instructor in psychiatry at the School of Medicine of the University of Virginia, and a consultant on government funded parapsychological research at the Stanford Research Institute (now known as SRI International).

[1] Tart was also integral in the theorizing and construction of the automatic ESP testing device called the ESPATESTER machine that was built at the University of Virginia.

[3] As well as a laboratory researcher, Tart has been a student of the Japanese martial art of Aikido (in which he holds a black belt), of meditation, of Gurdjieff's work, of Buddhism, and of other psychological and spiritual growth disciplines.

His primary goal is to build bridges between the scientific and spiritual communities, and to help bring about a refinement and integration of Western and Eastern approaches for knowing the world and for personal and social growth.

[17][18] Harris Chaiklin wrote that the book rejected medical evidence and laboratory experiments in favor for the opinions of marijuana users and probability statistics were inappropriately used.

[19] In 1981, Tart received the James Randi Educational Foundation Media Pigasus Award "for discovering that the further in the future events are, the more difficult it is to predict them.
