The Irish have evolved to be less intelligent than the British!
Here's our dear old The Irish Times to tell you about it:
Irish people are less intelligent than the British and have lower IQ scores than most European countries, a University of Ulster academic has claimed.
The average Irish IQ score is 96 compared with 100.5 in England and Wales and 97 in Scotland, according to Prof Richard Lynn, a former Economic and Social Research Institute (ESRI) psychologist and professor emeritus of the University of Ulster.
Four and a half points lower! Since IQ scores are the result of genetics as we learn from The Bell Curve there is clearly something more intellectually superior about British brains.
Oddly enough, the NYTimes favorite evo-psycho guy (before he retired) Nicholas Wade reported in 2007: English, Irish, Scots: They’re All One, Genes Suggest
Britain and Ireland are so thoroughly divided in their histories that there is no single word to refer to the inhabitants of both islands. Historians teach that they are mostly descended from different peoples: the Irish from the Celts, and the English from the Anglo-Saxons who invaded from northern Europe and drove the Celts to the country’s western and northern fringes.
But geneticists who have tested DNA throughout the British Isles are edging toward a different conclusion. Many are struck by the overall genetic similarities, leading some to claim that both Britain and Ireland have been inhabited for thousands of years by a single people that have remained in the majority, with only minor additions from later invaders like Celts, Romans, Angles , Saxons, Vikings and Normans.
I guess genes and IQ only matter when the comparisons are between different "races."
