Portugal: Regional Differences in Intelligence and Incomes

I found this. Now i'm not saying i agree or disagree but just wanted to share:

The differences between Lisbon and the rest are explained with the migration of higher IQ individuals from elsewhere in the country to the capital, similar to what was observed in England and France with London and Paris:

There are three points of interest in the results. First, IQ is highest in Central Lisbon, where it is approximately 7.5 points higher than in the other four regions, where the average IQ is approximately 99. This difference is similar to that in the British Isles, where the average IQ in London and the South-East was found to be 8.1 IQ points higher than in Ireland, which had the lowest IQ. A similar result has been reported for France by Montmollin (1958), where the highest IQ was found in Paris. In the case of the British Isles and France, it was proposed that the explanation for the capital cities to have the highest IQs is that over the course of many generations there has been some tendency for higher IQ individuals to migrate from the country to the capital cities (Lynn, 1979, 1980). These higher IQ individuals founded families who inherited their higher IQs and transmitted them to succeeding generations. The effect of this was to raise the average IQ in the capitals, and at the same time reduce the average IQ in the provinces. There is considerable evidence from various sources that migrants tend to have higher average IQs than non-migrants, probably because it requires a reasonably high IQ to migrate. For example, Maxwell (1969) reported that 17 per cent of a representative sample born in Scotland emigrated and these had an average IQ of 108. It is probable that in Portugal the high IQ in Central Lisbon is also a result of some tendency for higher-IQ individuals to have migrated from the country to the capital city over the course of many generations

Also the difference between Central Lisbon and the suburbs is explained with the presence of immigrants in the suburbs (a not so politically correct conclusion):

Second, as noted in the introduction, in the British Isles, France, the United States and Italy there are positive associations between regional IQs and per capita income. This is to some extent present in Portugal where the IQ and per capita income in Central Lisbon are both considerably higher than in the three provincial regions. However, there is an anomaly in Portugal in so far as in suburban Lisbon the per capita income is as high as in Central Lisbon, but the average IQ is the same as in the three provincial regions. We believe a possible explanation for this is that the average IQ of school students in suburban Lisbon has been reduced by the large number of mixed race immigrants from Brazil and other Latin American countries who have settled in suburban Lisbon in recent decades. The average IQ of mixed race mestizos and mulattos in Brazil has been given as 81 (Fernandes, 2001).

This country had always centred the total of his power and capital in Lisbon, that's one of the negative aspects of Portugal, people say that this is can't be solved due to our little size but Netherlands is much smaller (and more populated) and had divided his power, administration and financial capital between Amsterdam and Hague.

So it doesn't work as an excuse. We already saw the consequences of this centred power in Lisbon with the Earthquake of Lisbon in 1755.......
