adapted from other sources, such as the diaries of George A. Smith and Willard Richards, and only rendered by scribes as if it were in Smith's first-person voice. Historians also noted that Brodie had not used any material from the LDS Church archives. Scholars also echoed Fisher's critique of No Man Knows My History's reliance on unsourced and speculative depictions of historical figures' inner thoughts. Although Brodie's literary style invited reader's to feel sympathy for and identify with people portrayed in the book, critics said it relied on guesswork and sometimes outright invention of what someone may have been thinking or feeling. According to psychologist Charles Cohen, this approach "undercut the history." Brodie's use of psychoanalysis in her 1971 supplement was later considered incomplete and inconsistent with evidence of Smith's positive upbringing and healthy relationships with his parents. In No Man Knows My History, Brodie hypothesized that Smith had fathered five children through polygamous relationships: Oliver Buell, Orson Washington Hyde, Frank Henry Hyde, John Reed Hancock, and Moroni Pratt. In the 2000s, the Sorenson Molecular Genealogy Foundation, using Y-DNA testing, excluded Smith as the father of Buell, Hancock, and Pratt. Frank Henry Hyde's recorded date of birth precludes Smith's paternity, and whether or not Smith fathered Orson Washington Hyde has neither been proved nor disproved. At a 1995 USU symposium, scholars praised Brodie's accomplishments but generally agreed that No Man Knows My History made questionable interpretations, misused evidence, and had factual errors. Influence The significance and ground-breaking nature of Brodie's work is generally acknowledged within Mormon studies, and No Man Knows My History influenced the field in several lasting ways. The book "completely demolished", in the words of Jan Shipps, the hypothesis that the Book of Mormon was based on a novel manuscript written by Solomon Spaulding. Brodie also rejected earlier academic hypotheses that Smith was epileptic or paranoid and instead depicted Smith as rational and thoughtful. The interpretation of Smith as possessing all his faculties spread and persisted in scholarly studies of Mormonism. Also significantly, No Man Knows My History raised awareness of Smith's and Mormons' participation in politics and the resultant political dimension of both Mormon and anti-Mormon activities. No Man Knows My History also contributed to the development of a more open-minded approach to church history among Mormon scholars. Historian Marvin S. Hill urged future scholars to avoid extremes in studies of Joseph Smith and instead find
