Richard Van Wagoner, a freelance biographer, has here written a pshchoanalytical biography that, as Gary Bergera cautioned might happen when amateurs write psychobiography, reflects what happens when a biographer's "own psychological reactions can distort their material so that their discussion may actually reveal more about themselves than about their subjects" (Bergera in Sunstone 15 [December 1991]: 28-31). Van Wagoner diagnoses Sidney Rigdon as manic-depressive though there is no evidence by which a mental health professional could make such a diagnosis. Indeed, Van Wagoner's use of the DSM-III shows a shallow understanding of diagnostic procedure, including an inductive approach in which a diagnosis was made and symptoms are then created from the definition of the disorder. This approach is convincing to casual readers, but it is fundamentally flawed. In several places Van Wagoner uses sources that are not credible. For instance, he cites a "medical opinion" to substantiate his claims. The problem is that the "doctor" would have been four years old at the time of his observations, and dead for a full decade before his findings were published. Moreover, Van Wagoner misled readers by citing the original source for this reference when all evidence suggests that he only saw a reported version of it. There are two other significant failings in Van Wagoner's psychoanalysis and the conclusions he draws. Readers interested in learning more about these may email.
