Idiodynamics is the science of the idioverse. The idioverse consists of the population of events experienced by a single unique individual. This conception supersedes that of personality because the idioverse purports to be a more direct and objective formulation. The idioverse is understood, in large measure, by markers that are peculiar to the individual and are discovered through a study of the totality of the individual's expressed experience. Three types of norms afford these data for observation: the nomothetic, the demographic, and the idiodynamic. All are essential for an understanding of how the individual participates in the experience of the self and of others. A biogenic medium and a sociogenic medium overlap in the formulation of the idioverse, and these media overlap and converge to constitute a matrix that provides idiodynamic norms. Comprehension of the idioverse reveals the individual as a self-creative and dynamic process. Idiodynamics should be distinguished from the earlier idiographic approach to individuality. Psychoarchaeology is the reconstruction of biographical identities and/or sources. This methodology is well illustrated in Morton Prince's classic case of dissociation (Sally Beauchamp).
