Abstract: The nature of individual inconsistency in performance on trait measurements is an important topic in psychometrics because of its direct relevance to measurement reliability. Several studies have supported short-term inconsistency as a systematic source of variation among individuals by finding some evidence for generalizability and relationship to behavioral predictability. However, these findings are questionable, since these studies confounded change with short-term fluctuation in their response inconsistency measure. The current research separates these two sources of inconsistency in a reanalysis of the data from one major study on short-term consistency and finds little evidence for generalizability or a relationship to behavioral predictability. These results support the popular assumption that measurement error from short-term fluctuations is not due to systematic individual differences in response consistency, as well as supporting a more limited definition of the individual inconsistency construct.
