Construct validity in psychological tests.
The present interpretation of construct validity is not "official" and deals with some areas where the Committee would probably not be unanimous, but the present writers are solely responsible for this attempt to explain the concept and elaborate its implications.

Two taxometric procedures, MAMBAC and MAXCOV-HITMAX, provide independent tests of the taxonic conjecture and satisfactorily accurate estimates of theTaxon base rate, the latent means, and the valid and false-positive rates achievable by various cuts.

  • 1 December 1962
While I have not until recently begun any systematic research efforts on this baffling disorder, I felt that to share with you some of my thoughts, based though they are upon clinical impressions in the context of selected research by others, might be an acceptable use of this occasion.
Theoretical risks and tabular asterisks: Sir Karl, Sir Ronald, and the slow progress of soft psychology.
Abstract Theories in “soft” areas of psychology lack the cumulative character of scientific knowledge. They tend neither to be refuted nor corroborated, but instead merely fade away as people lose
Taxometric analysis. I: Detecting taxonicity with two quantitative indicators using means above and below a sliding cut (MAMBAC procedure)
Given two quantitative indicators of a conjectured latent taxon, a statistical function defined as the difference between the observed means for cases of one indicator falling above and below a sliding cut indicates whether the latent structure is taxonic or nontaxonic.

Comparative efficiency of informal (subjective, impressionistic) and formal (mechanical, algorithmic) prediction procedures: The clinical–statistical controversy.
Given a data set about an individual or a group (e.g., interviewer ratings, life history or demographic facts, test results, self-descriptions), there are two modes of data combination for a
Why Summaries of Research on Psychological Theories are Often Uninterpretable
Null hypothesis testing of correlational predictions from weak substantive theories in soft psychology is subject to the influence of ten obfuscating factors whose effects are usually (1) sizeable,
Clinical versus actuarial judgment.
Research comparing these two approaches to decision-making shows the actuarial method to be superior, factors underlying the greater accuracy of actuarial methods, sources of resistance to the scientific findings, and the benefits of increased reliance on actuarial approaches are discussed.
