This study tests the hypothesis that persons will express relatively independent degrees of preference for ambiguity in different experiential domains. An original measure consisting of four subscales was developed to assess individual differences in the theoretical, social, economic and aesthetic domains, and was administered to a student sample. Comparisons between split half reliabilities of each subscale, and correlations with other subscales support the hypothesis in the theoretical, social and aesthetic domains. Results are interpreted as indicating that tolerance for ambiguity may be stable within but not across experiential domains. It is suggested that appropriate measurement may best be achieved by conceptualizing tolerance for ambiguity as a domain specific trait. (Author)
