But go ahead and criticize SCIENCE you hypocrites.
The reality is that psychometric outcomes are correlated with various academic and socio-economicoutcomes. Far more so than any other variable in psychology. Hence the use of things such as SAT's and psychometric tests in organizations and the military. 

University of Delaware Professor Linda Gottfredson has noted that this has implications in diverse societies where there are different group averages. 

Gottfredson, L. S. (2005).
Implications of cognitive differences for schooling within diverse societies. Pages 517-554 in C. L. Frisby & C. R. Reynolds (Eds.), Comprehensive
Handbook of Multicultural School Psychology. New York: Wiley. 

It is also extraordinary that people who claim to believe in evolution are so surprised at the suggestion that groups differ. Consider:

1. Behavioural traits, including cognitive ability, are heritable.

2. Different environments and cultures may favor different traits (greater re-productive success).

3. There is evidence of 1 standard deviation shifts in population average occurring over a 1000 year period. Groups were separated for 50,000 years, why wouldn't you expect to see population differences?

As Jonathan Haidt writes, it's only a matter of time before genomics reveals the basis for these differences.

"But the writing is on the wall. Russian scientists showed in the 1990s that a strong selection pressure (picking out and breeding only the tamest fox pups in each generation) created what was — in behavior as well as body — essentially a new species in just 30 generations. That would correspond to about 750 years for humans. Humans may never have experienced such a strong selection pressure for such a long period, but they surely experienced many weaker selection pressures that lasted far longer, and for which some heritable personality traits were more adaptive than others. It stands to reason that local populations (not continent-wide "races") adapted to local circumstances by a process known as "co-evolution" in which genes and cultural elements change over time and mutually influence each other. ..

Recent "sweeps" of the genome across human populations show that hundreds of genes have been changing during the last 5-10 millennia in response to local selection pressures. (See papers (See papers by Benjamin Voight, Scott Williamson, and Bruce Lahn).

Also, see Rindermann et al 'Haplogroups as evolutionary markers of cognitive ability' Intelligence Volume 40, Issue 4, July–August 2012, Pages 362–375. The authors conclude:

"Based on their evolutionary meaning and correlation with cognitive ability these haplogroups were grouped into two sets. Combined, they accounted in a regression and path analyses for 32–51% of the variance in national intelligence relative to the developmental indicator (35–58%). This pattern was replicated internationally with further controls (e.g. latitude, spatial autocorrelation etc.) and at the regional level in two independent samples (within Italy and Spain). These findings, using a conservative estimate of evolutionary influences, provide support for a mixed influence on national cognitive ability stemming from both current environmental and past environmental (evolutionary) factors."
