His most recent claim to fame is his validation study on the effectiveness of Biographical Questionnaires to determine the suitability of a job applicant for the career as an air traffic controller. He also was lead signatory on a recent validation study on the effectiveness of the AT-SAT as a predictor of applicant suitability for a career as an air traffic controller. Apparently he feels strongly both ways. Wonder how he feels now that the BQ has been such a miserable failure.
