of Virginia, recorded case studies of young children who claimed to remember past lives. He published twelve books, including Twenty Cases Suggestive of Reincarnation, Reincarnation and Biology: A Contribution to the Etiology of Birthmarks and Birth Defects (a two-part monograph), European Cases of the Reincarnation Type, and Where Reincarnation and Biology Intersect. In his cases he reported the child's statements and testimony from family members and others, often along with what he considered to be correlates to a deceased person who in some ways seemed to match the child's memory. Stevenson also investigated cases where he thought that birthmarks and birth defects seemed to match wounds and scars on the deceased. Sometimes included in his documentation were medical records like autopsy photographs. As any claim of past life memory is subject to charges of false memories and the ease with which such claims can be hoaxed, Stevenson expected the controversy and skepticism of his beliefs that followed. He said that he looked for disconfirming evidence and alternative explanations for reports, but, as the Washington Post reported, he typically concluded that no normal explanation sufficed. Other academic researchers who have undertaken similar pursuits include Jim B. Tucker, Antonia Mills, Satwant Pasricha, Godwin Samararatne, and Erlendur Haraldsson, but Stevenson's publications remain the most well known. Stevenson's work in this regard was impressive enough to Carl Sagan that he referred to what were apparently Stevenson's investigations in his book The Demon-Haunted World as an example of carefully collected empirical data, and though he rejected reincarnation as a parsimonious explanation for the stories, he wrote that the phenomenon of alleged past-life memories should be further researched. Sam Harris cited Stevenson's works in his book The End of Faith as part of a body of data that seems to attest to the reality of psychic phenomena, but that only relies on subjective personal experience. Stevenson's claims have been subject to criticism and debunking, for example by the philosopher Paul Edwards, who contended that Ian Stevenson's accounts of reincarnation were purely anecdotal and cherry-picked. Edwards attributed the stories to selective thinking, suggestion, and false memories that result from the family's or researcher's belief systems and thus did not rise to the standard of fairly sampled empirical evidence. The philosopher Keith Augustine wrote in critique that the fact that "the vast majority of Stevenson's cases come from countries where a religious belief in reincarnation is strong, and
