Ian Wilson argued that a large number of Stevenson’s cases consisted of poor children remembering wealthy lives or belonging to a higher caste. He speculated that such cases may represent a scheme to obtain money from the family of the alleged former incarnation. Philosopher Keith Augustine has written "the vast majority of Stevenson's cases come from countries where a religious belief in reincarnation is strong, and rarely elsewhere, seems to indicate that cultural conditioning (rather than reincarnation) generates claims of spontaneous past-life memories." According to the research of Robert Baker many of the alleged past-life experiences investigated by Stevenson and other parapsychologists can be explained in terms of known psychological factors. Baker has written the recalling of past lives is a mixture of cryptomnesia and confabulation. Philosopher Paul Edwards noted that reincarnation invokes logicially dubious assumptions and is inconsistent with modern science.
