 The most promising of the empirical approaches to systematizing personality differences have been based on one critical assumption: Those individual differences that are of the most significance in the daily transactions of persons with each other will eventually become encoded in their language…[this] has a highly significant corollary: The more important is an individual difference in human transactions, the more languages will have an item for it (Goldberg 1981: 141–142, see also Saucier and Goldberg 1996b).
