A pity you and the author seem unfamiliar with Ron Unz's article or articles pointing out the absurdity of taking the old Irish IQ figures as strong evidence of genetic causes of difference on IQ tests from their cousins across the Irish Sea. I also think you omit the negative effects of Irish Catholicism on Irish achievement and intellectual development for many years, in striking contrast to the work of Irish missionaries about 1000 years earlier.

Ireland has actually not surpassed the UK economically: far from it, which is why the boggers are still coming over here in large numbers.
It is well known that Eire is a corporate tax haven, particularly for US companies. This has grossly dis torted Ireland's GDP and makes it appear that the country is much wealthier than it actually is.

Economists note that Ireland's distorted GDP is now distorting the EU's aggregate GDP,[106] and has artificially inflated the trade-deficit between the EU and the US.[107]
 

I suspect the 1969 difference might be caused by the UK having a better education system, schools in Ireland spent far too much time teaching religion. Today I think Ireland has on average a better education system than the UK

Charles Dilke may have his opinions. And yes there were such incidents as the Tasmanian genocide, but the British were definitely not the best race to rule the world on that account. Becuase there were some of the most pathetic genociders overall. In India they increased land under irrigation, brought Western medicine against diseases, brought stability and stopped inter-Indian War. What kind of incompetent pathetic genocide is this? Nigeria's population increased during British Nigeria period.

Even Chinua Acebe, the Nigerian Igbo writer who did criticize colonialism on the aspect of culture had to admit later in his book ‘There was a Country’, p. 43.

“The British governed their colony of Nigeria with considerable care. There was a very highly competent cadre of government officials imbued with a high level of knowledge of how to run a country. This was not something that the British achieved only in Nigeria; they were able to manage this on a bigger scale in India and Australia. The British had the experience of governing and doing it competently. I am not justifying colonialism. But it is important to face the fact that British colonies were, more or less, expertly run.”

Chinua Achebe also sez
“Before (British Nigeria), justice may have been fierce but it could not be bought or sold . . . . There were titles and distinctions, but they were gained by hard work ….Now all that is changed.”

Sad and pathetic genociders. Definitely by Dilke's standards, the Brits were incompetent race to assume world Domination. LOL.
And talking about Maoris (since that link does mention Maoris ), when the Maoris exterminated the peaceful Morioris, did they take IQ tests before their dastardly deed????
