Statistika te opovrgava. Najveći dio inteligencije (oko 75%) je genetski
uvjetovan.

Consequently, in the context of the nature versus nurture debate, the
"nature" component appears to be much more important than the "nurture"
component in explaining IQ variance in the general population.

In the case of the inheritance of IQ or a certain degree of giftedness,
the relatives of probands with a high IQ exhibit a comparably high IQ
with a much higher probability than the general population. Bouchard and
McGue (1981) have reviewed such correlations reported in 111 original
studies in the United States.[5] The mean correlation of IQ scores
between monozygotic twins was 0.86, between siblings, 0.47, between
half-siblings, 0.31, and between cousins, 0.15. From such data the
heritability of IQ has been estimated at anywhere between 0.40 and 0.80
in the United States. The reason for this wide margin appears to be that
the heritability of IQ rises through childhood and adolescence, peaking
at 0.68 and 0.78 in adults, leaving the overwhelming majority of IQ
differences between individuals to be explained genetically.
