An ambitious scientist dreams of overturning conventional wisdom and establishing a new paradigm that will provide a grand theoretical synthesis of the ®eld. This commentary examines the articles of this special issue to distinguish what might be new from what is deÂjaÁ vu to traditional, mainstream trait psychology. To accomplish this, the commentary begins with an exposition of how trait concepts are used in the natural sciences. This exposition is meant to correct a straw-man concept of traits, oered by some psychologists, asùnmodulated consistencies in. .. behavior across time and diverse situations' (Kenrick and Funder, 1988, p. 24). After presenting an accurate view of the trait concept, I examine what the authors of these articles oer as alternatives to traits, traditionally conceived. This examination shows that the authors occasionally misrepresent traits, and that in some cases their oered alternatives are actually quite similar to traditional trait conceptions. I end by describing what the traditional trait approach considers to be reasonable goals for personality psychology and the most promising methods for reaching those goals. In its most generic sense, the term trait refers to any distinguishing characteristic, feature, property, or quality by which we identify something. More speci®cally, we have traits that refer to (a) physical appearance, (b) observable behavior patterns, and (c) inferred structural properties. For example, white and granular are traits that describe the physical appearance of both sodium chloride (table salt) and silicon dioxide (sand). Salt and sand show dierent behavior patterns in particular situations; salt is water-soluble whereas sand is non-water-soluble. Chemists explain what we observe about salt and sand in terms of their inferred atomic structures.
