What Are the Most Important Dimensions of Personality?Evidence from Studies of Descriptors in Diverse Languages

Progress is reviewed with respect on how attributes of personality and character can best be organized and structured. Key insights on this important scientific issue have been gained by a lexical approach, which posits that the degree of representation of an attribute in language corresponds substantially with the general importance of the attribute in real-world transactions. The rationale for studying the language of personality is explained, followed by a review of the most salient findings from lexical studies of person-descriptors in 16 languages. In these studies, oneand two-factor structures are found to be not only the most parsimonious but also the most easily replicated across variable selection procedures, and across languages and cultures. Structures with more factors are likely to show a comparative predictive advantage, but replicate more unevenly. Lexical studies appear to support a six-factor model at least as well as the Big Five. Future research attention should be directed toward inclusion of a wider range of individual differences, integration with models of temperament, and the search for causal factors and underlying mechanisms that are associated with the best-replicated personality dimensions. How personality attributes are best organized and structured is an important scientific issue. Studies of person descriptors in diverse languages have been crucial for addressing this issue. After explaining the rationale for such studies, I will discuss insights that have been gained from them. Because inquiries into the structure of attributes depend significantly on how personality and character are defined, I begin there. Defining Personality Definitions of personality are consequential: They affect how one selects variables when studying personality phenomena. And these definitions vary fairly widely. Allport (1937) reviewed definitions of the concept of personality, cataloging 50 distinct meanings. Allport’s own preferred definition – ‘personality is the dynamic organization within the individual
