In 1918 Findlay attended a séance with the direct voice medium John Campbell Sloan at a spiritualist church in Glasgow. During the next five years Findlay attended many seances at the medium's home and became convinced spirit voices were speaking through Sloan. However, the psychical researcher J. Malcolm Bird investigated Sloan and wrote he had no doubt that all the voices heard could be produced by the medium talking into the trumpet in a normal fashion. Bird also wrote the information given to the sitters could have easily been taken from public records and there was a lack of control in the séances. Bird wrote that "the phenomena themselves were not particularly impressive; with the intermittent freedom of the medium, it seemed simple enough for him to have done most of them himself." Findlay's On the Edge of the Etheric defended Sloan's direct voice mediumship and supported the existence of an etheric body. The book was negatively reviewed in the journal Nature as anti-scientific. According to the review "from reading Mr. Findlay's records, the scientific method might be thought not to exist. He seems to have no appreciation of the implications underlying many of his remarks; no desire to see the phenomena described in accurate and scientific terminology."
Spiritualism
Findlay in 1920 founded the Glasgow Society for Psychical Research. In 1923 he took part in the Church of Scotland's enquiry into psychic phenomena. In the same year, he retired from his profession and purchased Stansted Hall in Stansted, England, a manor house built in 1871. In 1932, he became a founding member of Psychic News, a Spiritualist newspaper, along with Hannen Swaffer and Maurice Barbanell. He helped to found the International Institute for Psychical Research, of which he became the chairman. He also became an honorary member of both the American Foundation for Psychical Research, Edinburgh Psychic College and the honorary president of both the Institute of Psychic Writers and Artists and the Spiritualists' National Union. In his will, he left Stansted Hall to the Spiritualists' National Union as a college for the advancement of Psychic Science, which was named the Arthur Findlay College of Psychic Science after him.
In 1938, the psychical researcher Nandor Fodor investigated the Thornton Heathpoltergeist case that involved Mrs. Forbes. According to Rosemary Guiley "Fodor asserted that the psychosis was an episodic mental disturbance of schizophrenic character, and that Mrs. Forbes' unconscious mind was responsible for the activities finally determined to be fraudulent. Fodor eventually identified the cause as sexual trauma that had occurred in Mrs. Forbes's childhood, and had been repressed." Because he was skeptical of the case, Fodor was heavily criticized by spiritualists and was dismissed from his post at the International Institute for Psychical Research. Findlay, the founder of the Institute, did not approve of his research and resigned. Fodor was attacked in the Spiritualist newspaper, Psychic News which he sued for libel.
