Sex and cross-cultural differences in the estimated multifaceted intelligence quotient score for self, parents and siblings

Over four hundred young people from Britain, Hawaii and Singapore estimated their own, their parents' and their siblings' IQ score on each of Gardner' s (1983) fundamental human intelligences: verbal (linguistic). logical (mat hematical), spatial, musical, body-kinesthetic, interpersonal and intrapers onal. They also answered six simple questions concerning intelligence tests . There were both cultural and sex differences in the estimation of overall own intelligence score. Males gave higher scores than females (109 vs 107) while the British gave the highest score (109) compared with the Singapore ans (106) and Hawaiians (104). Factor analysis of the seven dimensions yiel ded either a two or three factor solution, the latter being verbal (verbal, inter-intrapersonal), mathematical (mathematical and spatial), and musical (musical, body-kinesthetic). There were consistent sex differences in the estimations of the three factors for self, but not of parents, and only mar ginally of sisters. Males more than females, and the British more than the other groups, were more likely to believe in sex and race difference in int elligence. (C) 1999 Elsevier Science Ltd. All rights reserved.
