    An important study indicates
    that breastfeeding is effective in raising IQ by about six
    points, but only for the large portion of the population
    having one of two alleles at a particular site that regulates
    fatty acids and is influenced by breast milk (Caspi et al.,
    2007). Those having another allele at that site did not
    benefit from breastfeeding, but people with that allele are in
    a small minority. This finding of genetic contingency
    speaks against the possibility of a social-class confound in
    the breastfeeding–IQ relationship, because the benefit of
    breastfeeding occurred for children with the two more
    common alleles regardless of the mother’s social class and
    did not occur for children with the less common allele,
    again regardless of social class. Moreover, it was only the
    child’s allele at the relevant site, not the mother’s, that
    mediated the influence on IQ. Another study manipulated
    breastfeeding in a large randomized control study and also
    found about a 0.5 SD difference in IQ (Kramer, 2008).

    Have the right genes (expressed by the right alleles) and exposed to the correct nutrition and you achieve a higher IQ.
