§ 1607.9 No assumption of validity.

A. Unacceptable substitutes for evidence of validity. Under no circumstances will the general reputation of a test or other selection procedures, its author or its publisher, or casual reports of its validity be accepted in lieu of evidence of validity. Specifically ruled out are: assumptions of validity based on a procedure's name or descriptive labels; all forms of promotional literature; data bearing on the frequency of a procedure's usage; testimonial statements and credentials of sellers, users, or consultants; and other nonempirical or anecdotal accounts of selection practices or selection outcomes.
