[IPAC-List] Speed vs Power Tests

Mike offered his 2011 IOP focal article to the list.  I offer my 
(unpublished) response to his article, in partial rebuttal (attached).

Concerning the subject line of this thread, I think the field of I/O. 
may be overlooking an opportunity to both increase validity and decrease 
adverse impact.  If speed is a valid predictor for some jobs, and if 
speed shows no intergroup differences in mean scores, we might 
reasonably expect to increase validity and decrease adverse impact by 
including in the selection battery a job-related measure of work speed. 
I find this possibility to be exciting and encouraging.  Do you?
