In 3 phases of analysis on one Australian sample, the concept of a fuzzy variable was used to develop new sex-type, prestige, and Holland interest scales from the Occupational scales of the Strong Interest Inventory (SII). Theoretically, the scales provide a basis for understanding avoidant reactions and the influence of sex type and prestige on interests. Phases 1 and 2 of the study describe intercorrelations among three measures of Holland themes and measures of sex type and prestige (occupational social space; L. S. Gottfredson, 1981). Phase 3 describes similar relationships but among scales derived from scoring the Occupational scales of the SII separately for distinctive likes and distinctive dislikes. Comments are offered about potential counseling and research uses for the new measures.
