[IPAC-List] differential validity?

[Joel Wiesen]

What do you think of this apparent support for differential validity 
(from a recent Personnel Psych article)?

Might it imply that education is problematic as selection tool when the 
applicant group includes minorities and/or women?  Would it imply that 
an education requirement may be unfair to minorities and/or women?

"Finally, Hypothesis 6 predicted that the education-performance 
relationship will be stronger for men (vs. women; Hypothesis 6a) and for 
Caucasians (vs. non-Caucasians; Hypothesis 6b). With respect to the 
relationship between education level and task performance, we found that 
the relationship was more positive for Caucasians than for other racial 
groups and for men than for women. Further, we found that the 
relationship between education and OCB was more positive for Caucasians 
than for other racial groups. These results provide some support for 
Hypothesis 6a and Hypothesis 6b."
