Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences (Reese, 1943, p. 49). [9]

Classical test theory is an influential theory of test scores in the social sciences. In psychometrics, the theory has been superseded by the more sophisticated models in item response theory (IRT) and generalizability theory (G-theory).
Psychological research risks harming the subjects of the research. In order to prevent that harm, proposed studies are usually approved by an institutional review board to ensure that the risks to the research subjects are justified by the anticipated benefits. [2]
