title: Distinctive disorders are less prevalent.
abstract: To test the hypothesis that nosologies are biased towards recognizing highly distinctive syndromes and therefore conflate those that are less distinctive, eight subjects judged the distinctiveness of 33 DSM-IV disorders and 20 rheumatic disorders. As predicted, judged distinctiveness was negatively correlated with prevalence for both sets of disorders.
