Séance

[2] The 1887 Seybert Commission report marred the credibility of Spiritualism at the height of its popularity by publishing exposures of fraud and showmanship among secular séance leaders.

[3] Modern séances continue to be a part of the religious services of Spiritualist, Spiritist, and Espiritismo churches today, where a greater emphasis is placed on spiritual values versus showmanship.

Black Hawk was a spirit who was often contacted by the Spiritualist medium Leafy Anderson and he remains the central focus of special services in the African American Spiritual Churches that she founded.

[5] In the Latin American religion of Espiritismo, which somewhat resembles Spiritualism, séance sessions in which congregants attempt to communicate with spirits are called misas (literally "masses").

Other modes of communication may also be attempted, including psychography or automatic writing, numbered raps, levitation of the table or of spirit trumpets, apports, or even smell.

This is the type of séance that is most often the subject of shock and scandal when it turns out that the leader is practicing some form of stage magic illusion or using mentalism tricks to defraud clients.

Scientific skeptics and atheists generally consider both religious and secular séances to be scams, or at least a form of pious fraud, citing a lack of empirical evidence.

Stage magicians like John Nevil Maskelyne and Harry Houdini made a side-line of exposing fraudulent mediums during the late 19th and early 20th centuries.

Critics of channeling—including both skeptics and believers—state that since the most commonly reported physical manifestations of channeling are an unusual vocal pattern or abnormal overt behaviors of the medium, it can be quite easily faked by anyone with theatrical talent.

Another criticism of spirit board communication involves what is called the ideomotor effect which has been suggested as an automatism, or subconscious mechanism, by which a Ouija-user's mind unknowingly guides his hand upon the planchette, hence he will honestly believe he is not moving it, when, in fact, he is.

In a series of fake seance experiments (Wiseman et al.. 2003) paranormal believers and disbelievers were suggested by an actor that a table was levitating when, in fact, it remained stationary.

In another experiment the believers had also reported that a handbell had moved when it had remained stationary and expressed their belief that the fake seances contained genuine paranormal phenomena.

[19] Popular 19th-century trance medium lecturers include Cora Scott Hatch, Achsa W. Sprague, Emma Hardinge Britten (1823–1899), and Paschal Beverly Randolph (1825–1875).

Among the notable people who conducted small leader-assisted séances during the 19th century were the Fox sisters, whose activities included table-rapping, and the Davenport Brothers, who were famous for the spirit cabinet work.

Notable people who have attended séances and professed a belief in Spiritualism include the social reformer Robert Owen; the journalist and pacifist William T. Stead;[23] William Lyon Mackenzie King, the Prime Minister of Canada for 22 years, who sought spiritual contact and political guidance from his deceased mother, his pet dogs, and the late US President Franklin D. Roosevelt;[24] the journalist and author Lloyd Kenyon Jones; and the physician and author Arthur Conan Doyle.

[25] A number of artists, including abstractionists Hilma af Klint, the Regina Five, and Paulina Peavy have given partial or complete credit for some of their work to spirits that they contacted during seances.

[30] The psychical researcher Hereward Carrington exposed the tricks of fraudulent mediums such as those used in slate-writing, table-turning, trumpet mediumship, materializations, sealed-letter reading and spirit photography.
