Charles Richet: He accepted cryptesthesia, telekinesis, ectoplasm, materializations, and premonitions as abundantly proved...[sobre Eupapia Palladino:] The report admitted the reality of puzzling phenomena, expressing also the conviction that the results obtained in light, and many of those obtained in darkness, could not have been produced by trickery of any kind.
http://www.answers.com/topic/charles-robert-richetSir William Crookes: ...was a member of the Society for Psychical Research from its founding in 1883 and served as president of the society from 1896 to 1899. During his investigations, Crookes discovered that a very successful spirit medium, Mary Rosina Showers, was a fraud, but said nothing and reported nothing about his discovery. He and spirit medium Daniel Dunglas Home were on a very close personal basis, and his endorsement of Home's powers has always been a strong point made by the spiritualists to support their claims about Home. However, Crookes has been shown to be a dupe of such other mediums as Florence Cook and others exposed or confessed as fakes, so his validation of Home is highly suspect.

His defense would lead to a lively discussions with Eleanor Sidgwick in the Journal of the Society for Psychical Research in 1888.
http://www.spiritwritings.com/alfredrusselwallace.htmlWilliam Barrett: In spite of the fact that controls in the early days of psychical research were rather slack by modern standards, a great number of mediums were exposed as frauds. In 1876 ---- the same year that Crookes and Barrett debated the subject ---- three mediums who had large followings were caught red-handed as frauds.(

Sobre poltergeists: Early psychic investigators, such as Sir William Barrett and Federic Mehers and Nandor Fodor proposed these manifestations were not caused by any spirit or demon, but by human agents suffering from repressed anger, hostility, and sexual tension.
http://mtskeptics.homestead.com/Poltergeist.htmlLord Rayleigh: Meanwhile Myers, Lord Rayleigh and A. J. Balfour had joined Sidgwick in the study of spiritualism at first hand, and they experimented in their own homes with a number of mediums. It was not a happy experience, for apart from the sordid and deliberate fraud which they often struck, it must have felt like leaving the green lawns of the Backs for to pass from the rarefied air of Cambridge semi-hysterical emotionalism of the average séance.
