The use of heritabilities of anthropometric measures and performance tests in personnel selection

An analogy exists between the mathematical models of psychological test theory and quantitative genetics. From this analogy we can conclude, that longitudinal correlation and heritability in the broad sense are equivalent expressions for the reliability in the long run. Since long-range prediction is the aim of index construction for personnel selection in athletics and other applied fields, we recommend to use heritability as a weighting factor for phenotypic scores in order to calculate true scores and to eliminate error variance.
