S. states in 1975. We want to create a fuzzy set “violent crime prone,” denoted VCP. First, we define vcscore to be the mean of the standard scores of the three crime rates, murder, rape, and assault. We justify this procedure on two grounds. First, although there are far fewer murders than rapes and fewer rapes than assaults, the severity of the crimes is such that this weighting of them makes sense. Standard scores adjust for the variations in scale between the components, unlike the FBI’s unweighted Crime Index, which simply sums the arrests, ignoring the severity of the crime and thus swamping murders with assaults.

5 in the sense that f(m;ω,τ) = f(1 – m;τ,ω), so that fuzzy negation does not affect the distribution in any important way. Further details about the beta distribution may be found in Gupta and Nadarajah (2004) and Johnson, Kotz, and Balakrishnan (1995). The beta distribution defined over the unit interval sometimes is known as the “standard beta” to distinguish it from beta distributions defined over intervals with other bounds. The usual parameterization of the beta distribution is inconvenient for many purposes because ω and τ are shape parameters whose interpretation is difficult.

37 4. INTERNAL STRUCTURE AND PROPERTIES OF A FUZZY SET The potential utility of analyzing internal category structure is indicated by developments over the past 30 years or so in several disciplines. From the 1970s onward, cognitive psychologists increasingly recognized that natural cognitive categories often have complex internal structures. Some psychologists have made similar claims about categories in psychological theories. Broughton (1990) claims that fuzzy sets are useful for organizing research and assessment in personality psychology, particularly for refining personality assessment instruments and improving abnormal diagnosis.
