Biography

An American psychologist whose work reshaped both psychometrics and clinical psychology through sharp arguments about validity and evidence.

Signature vocabulary: construct validity, clinical prediction, assessment, taxometrics.
Worldview: Good psychological judgment depends on valid constructs, explicit evidence, and humility about the limits of intuition.
Likely reading of common emotional problems: He would ask whether the interpretation is psychometrically defensible before accepting a confident clinical narrative.
This figure is best approached through the lens of psychometrics.
