According to Arthur Conan Doyle, Carrington was not popular with spiritualists. James Hyslop died in 1920, and immediately strife broke out between the membership as the Society divided into two factions, one broadly pro-Spiritualism, indeed often Spiritualists, and the other 'conservative' faction favoring telepathy and skeptical of 'discarnate spirits' as an explanation for the phenomena studied, or simply skeptical of the phenomena's existence. In 1923 a prominent Spiritualist, Frederick Edwards, was appointed President, and the conservative faction led by Gardner Murphy and Walter Franklin Prince declared that the Society was becoming less academic. In the same year the ASPR lost 108 members. New members joined the society and William McDougall a past President and Prince both became alarmed at the number of "credulous spiritualists" that joined the ASPR. In 1925 Edwards was reappointed President, and his support of the mediumistic claims of 'Margery' (Mina Crandon) led to the 'conservative' faction leaving and forming the rival Boston Society for Psychical Research in May, 1925. From this point on the ASPR remained highly sympathetic to Spiritualism until 1941, when the Boston Society for Psychical Research was reintegrated into the ASPR. The Boston Society for Psychical Research (BSPR) was founded in April 1925 by former research officer Walter Franklin Prince of the ASPR. Other founding members were William McDougall, Lydia W. Allison and Elwood Worcester. They were alarmed by the ASPR support for the purported medium Margery (Mina Crandon) and suppressing any reports unfavourable to her. Joseph Banks Rhine claimed to have observed Crandon in fraud in a séance in 1926. According to Rhine during the séance she was free from control and kicked a megaphone to give the impression it was levitating. Rhine's report that documented the fraud was refused by the ASPR, so he published in it in the "Journal of Abnormal and Social Psychology". In response, defenders of Crandon attacked Rhine. Arthur Conan Doyle published an article in a Boston Newspaper claiming "J. B. Rhine is an Ass." There was a significant split in the history of American psychical research: the American Society for Psychical Research had become dominated by those sympathetic to Spiritualism; the Boston Society favored a naturalistic explanation (such as telepathy; yet telepathy within the laws of undiscovered physics) for purported mediumship and was critical of the purported mediumship of Mina Crandon in particular.
