In the 1960s and 1970s, LeShan conducted extensive research in the field of parapsychology. In his book The Medium, the Mystic, and the Physicist: Toward a General Theory of the Paranormal, he investigated paranormal topics, mystical thought and quantum mechanics. In the book LeShan claimed to have tested his hypothesis of "clairvoyant reality". He said the results were a success and he could heal with mental power and train others to do the same. However, Tim Healey wrote the results were not convincing as nine of his students had eight attempts at using a clairvoyant training technique and all scored four to fives misses.

LeShan received a bachelor degree from The College of William and Mary, a masters from University of Nebraska and a Ph.D. in Human Development from the University of Chicago. He taught at Pace College, Roosevelt University, and the New School for Social Research.
