He is best known for his study of the medium Helen Smith (or Hélène Smith - a pseudonym for Catherine Muller) who relayed information about past lives through a trance state, entitled From India To The Planet Mars (1899). Flournoy described her outpourings as the products of cryptamnesia and as 'romances of the subliminal imagination,' - as evidence of the unconscious mind.
His book Spiritism and Psychology (1911) translated by Hereward Carrington claimed more broadly that mediumship could be explained by suggestion and telepathy from the medium's subconscious mind and that there was no evidence for the spirit hypothesis.
Flournoy was a contemporary of Freud, and his work influenced C. G. Jung's study of another medium - his cousin Hélène Preiswerk - which was turned into Jung's doctoral dissertation in 1902. Jung also used Flournoy's publication of the autosuggestive writings of Miss Frank Miller as the starting-point for his own book Psychology of the Unconscious. Jung was also influenced by Flournoy's concept of a prospective element in the unconscious, laid out most clearly in his 1908 paper on 'Anti-Suicidal Teleological Automatisms', where he argued that last minute visions in suicides confirming the value of living served the (unconscious) purpose of preserving life.
Flournoy was also one of the few scholars of his time to embrace William James' view of the prime reality of non-dual consciousness (which he dubbed "sciousness") as expressed in his essay, Radical Empiricism. He published an introductory work, The Philosophy of William James, in 1911.
