All measurements must contend with unreliability. No measure is free of measurement error. More attention must be paid to measurement error in all psychological research. The problem of reliability is more severe when rating scales are involved. Many of the constructs in...

Today most conclusions about cumulative knowledge in psychology are based on meta-analysis. We first present an examination of the important statistical differences between fixed-effects (FE) and random-effects (RE) models in meta-analysis and between two different RE procedures, due to Hedges...

A recently developed procedure produces substantial improvements in the accuracy of corrections for range restriction and reveals that predictive validities of employment selection methods are higher than previously thought. This study applied this procedure to meta-analytic validities of 2...

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to under-correction, but this error has been assumed to be small. Using validity generalization data sets for 4...

We respond to the three comments on our recent article in the August issue of Academy of Management Perspectives (Le, Oh, Shaffer, & Schmidt, 2007), which highlights the importance of methodological advances in human resource research. By concentrating on tangential aspects of our article, these...
