FYI-
A new Aguinis et al. study again shows that the absence of differential
prediction seen in aggregational analyses of criterion related validity
studies hides actual differential prediction in both directions (under
prediction and over prediction) seen in individual studies.
The authors summarize with this analogy:
"The British writer and politician Benjamin Disraeli (1804–1881) stated
... 'A man eats a loaf of bread, and another man eats nothing;
statistics is the science that tells us that each of these men ate half
a loaf of bread.'"

prediction generalization in college admissions testing. Journal of
Educational Psychology, 108, 1045-1059.
