All respondents completed an online intelligence test,derived from the Q1000 intelligence test of Meurs HRM advisors. Results show aneffect size of .40 for the overall score on the test. Effect sizes for the subtests variedfrom .09 for Syllogisms to .39 for Vocabulary. The authors conclude that fraud paysoff.
