5. Discussion
Based on our model, it appears that national cognitive
ability is confounded with the general development of
society. This is shown by the high correlations with HDI and
the observation that in three analyses HDI accounted for the
largest mean share of the variance in national cognitive
ability. The mean across two regressions and one path
analysis for this variable was 48%. Haplogroups do however
also appear to be significant predictors of cognitive ability
(mean across two regressions and path analysis: 40%). They
are especially strong predictors when grouped, with the first
set (A, positively correlated) accounting for 15% of the
variance and the second set (B, negatively correlated)
accounting for 38% of the variance (sum: 53%). Interestingly,
controlling for spatial autocorrelation had no effect on the
predictive validity of the models, which suggests that the
relationships are largely spatially independent. | m******a

Fifth, while this study sheds light on possible evolutionary
influences on national differences in cognitive ability today, it
tells us nothing about the genetic basis (i.e. common polymorphisms)
of intelligence differences, which thus far remain
largely unidentified (those that have been identified explain only
a small fraction of variance) (e.g. Deary, 2012; Meisenberg,
2003). Therefore, while these findings are intriguing, there can
be no certainty about the ways in which genes influence the
neurological processes and structures undergirding cognitive
ability until the genes responsible are elucidated. The missing
link still needs to be found. |
