The use of psychometric tests in personnel selection has been regarded with an extraordinary degree of suspicion and scepticism. This is especially true when selection occurs in respect of a diverse applicant group. Concern is expressed about the seemingly uncritical embracing of specific tenets related to the use of psychometric tests in personnel selection in the absence of any systematic coherent psychometric argument to justify these beliefs. The absence of such a supporting psychometric rationale seems unfortunate in as far as it probably would inhibit the independent critical evaluation of the psychometric merits of these generally accepted beliefs. Specific beliefs related to selection fairness, measurement bias and adverse impact are critically examined.
