The hypothesis further states that lay conceptual schemes “tend to be innacurate with respect to how behaviors covary, confusing ‘what is like what’ with ‘what goes with what’” (Shweder&D'Andrade, 1979), and that interbehavior correlations derived from memory‐based ratings cannot be considered valid evidence for the objective existence of proposed personality traits, factors or syndromes.

That “critique,” it is argued, is neither a test of the systematic distortion hypothesis nor a critique. What Lamiell, Foss, and Cavenee demonstrate is that the validity of the systematic distortion hypothesis does not depend upon the unrealistic assumption that observers are capable of reporting onl
