A total of 378 Hong Kong adolescents estimated their own and their parents' IQ score on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual and naturalistic. They answered three simple questions concerning intelligence and intelligence tests. There were sex differences in eight of the 10 self‐estimates except for verbal and interpersonal. Male participants gave higher scores than female participants. Factor analyses of the 10 dimensions yielded a two‐interpretable‐factor solution: personal–social–spiritual intelligence and academic–arts–kinesthetic intelligence. There were consistent sex differences in the estimates of the academic–arts–kinesthetic intelligence factor for oneself, but not for parents, while there were sex differences in the estimates of the personal–social–spiritual intelligence factor for oneself and for mother, but not for father. The two factor scores were predicted by both gender and belief about intelligence. [Copyright of High Ability Studies is the property of Routledge.
