The thesis of these volumes is that the study of personality traits has advanced towards 'normal science' in the sense of a Kuhnian paradigm (cf. Eysenck, 1981; Kuhn, 1962). That is, most researchers in this area share a set of common core beliefs supported by empirical evidence. These include the relative stability of traits over time, a significant genetic and biological influence on personality, and relevance of traits to many areas of everyday life.
