Mental Radio

Mental Radio documents Upton Sinclair's investigation into the psychic abilities of his wife Mary Craig Sinclair during her period of depression. The book details a series of experiments where Mary attempted to replicate drawings made by her brother, with Sinclair recording the results of 290 trials. The publication garnered attention from notable figures, including Albert Einstein who wrote the preface for the German edition. Psychical researcher Walter Franklin Prince conducted an independent analysis of the results in 1932, publishing his findings in the Boston Society for Psychical Research bulletin. Despite the personal nature of the experiments and their departure from controlled scientific methods, the book presents the data and observations in detail. Sinclair catalogs the successes, partial matches, and failures of the trials while attempting to maintain objectivity in his documentation. The book stands as an artifact of early 20th century investigations into telepathy and psychic phenomena, reflecting both the period's growing interest in paranormal research and the challenges of studying such phenomena through a scientific lens.
