Yes, Mitchell has always been an advocate for unconventional scientific views. On Apollo 14 he performed esp experiments with parapsychologists on earth without permission of NASA and unbeknownst to his crewmates. He also believes in remote healing:
Mitchell's interests include consciousness and paranormal phenomena. During the Apollo 14 flight he conducted private ESP experiments with his friends on Earth.[3] In early 1973, he founded the nonprofit Institute of Noetic Sciences (IONS) to conduct and sponsor research into areas that mainstream science has found unproductive, including consciousness research and psychic events.
Mitchell says that a teenage remote healer who lives in Vancouver and uses the pseudonym Adam Dreamhealer, helped heal him of kidney cancer at a distance. Mitchell said that while he never had a biopsy (the definitive test for cancer), "I had a sonogram and MRI that was consistent with renal carcinoma." Adam worked (distantly) on Mitchell from December of 2003 until June of 2004, when the "irregularity was gone and we haven't seen it since."
