The self-other knowledge asymmetry in cognitive intelligence, emotional intelligence, and creativity

The self-other knowledge asymmetry model (SOKA) assumes that some personality traits might be open to oneself and other persons ('open area'), while other traits are more accurately perceived by others ('blind spot'); a third group of traits might be visible only to oneself and not to others ('hidden area'), and finally a trait might neither be visible to oneself nor to one's peers ('unknown area'). So far, this model has been tested only for personality traits and general intelligence, not for more specific abilities; to do so was the novel intention of our study. We tested which of six abilities (verbal, numerical, and spatial intelligence; interpersonal and intrapersonal competence; and creative potential/divergent thinking ability) are in which SOKA area. We administered performance tests for the six abilities in two samples - 233 14-year-olds and 215 18-year-olds - and collected self-and peer-ratings for each domain. Numerical intelligence and creativity were judged validly both from self-and peer-perspectives ('open area'). In the younger sample verbal intelligence was validly estimated only by peers ('blind spot'), whereas the older group showed some insight into their own abilities as well ('blind spot' to 'open area'). While in the younger group only the pupils themselves could validly estimate their intra-and interpersonal competence ('hidden area'), in the older group peers were also successful in estimating other's interpersonal competence, albeit only with low accuracy ('hidden area' to 'open area'). For 18-year-olds, spatial ability was in the hidden area too, but in 14-year-olds this could neither be validly estimated by pupils themselves nor by peers ('unknown area'). These results implicate the possibility of non-optimal career choices of young people, and could, therefore, be helpful in guiding professional career counselling.
