In a major review of psychological testing, Meyer et al. (2001) concluded that psychological test validity is compelling and comparable to medical test validity. In practice we often get validity coefficients in the .10-.40 range. If we compare these correlations with the perfect upper limit of 1.00, we may feel disappointed with our results. Meyer et al. Stated: “However, perfect associations are never encountered in applied psychological research, making this benchmark unrealistic. Second, it is easy to implicitly compare validity correlations with reliability coefficients, because the latter are frequently reported in the literature. However, reliability coefficients (which are often in the range of r=.70 or higher) evaluate only the correspondence between a variable and itself. As a result they cannot provide a reasonable standard for evaluating the association between two distinct real-world variables
