“the DSM practice of putting expert opinions into writing and only then conducting tests of reliability and validity cannot lead to an acceptable classification system.

Instead, researchers must turn to objective, empirical methodologies to discover the dimensions or personality pathology, letting the data fall where they may and letting the data determine how personality disorder is best classified”
