A method for collecting data relating to human performance skills and/or attributes comprising the steps of creating a questionnaire relating to the human performance skills of a target individual and establishing a rating scale for responses to the questionnaire. The rating scale comprises a dual sided continuum. The middle point on the dual sided scale is associated with the proper amount of the performance skill. The markers on the first side of the dual sided scale are associated with exhibiting too much of the human performance skill and the markers on the other side of the dual sided scale are associated with increased intensity of the human performance skill. Preferably, pairs of questionnaire elements are generated that relate to opposing but complementary performance skills to exhibit the individual's versatility in terms of dichotomies. The questionnaire results are compiled and a report is generated that that displays the results.
