Nals,
If the facts you presented are correct or really prove anything..... explain how Cuba, a much poorer nation than the DR, with much less access to certain types of information from sources such as the internet and world media, (but has a better educational and health care system and a much higher national literacy rate and much lower infant mortality rate...comparable to wealthier countries), has basically the same IQ scores as the DR?
Cuba is actually wealthier than the DR ($9,500 vs. $8,100 respectively),a difference of only $1,400. Puerto Rico, having the same IQ level of the DR, is much wealthier than both at c. $17,000.
Yet, Haiti lags the DR by $6,800, lags Cuba by $8,200, and Puerto Rico by $15,700.
Why the difference?
PR is under direct US influence and rule, a country with an average IQ of 98 and a per capita income surpassing $40,000.
Cuba is under a comunist/socialist dictatorship that has, as of late, been able to prop its economy thanks to generous help from Venezuela.
Dom. Rep. is under capitalism, politically independent, and thus; its increasing development level and relatively high economic growth rates (on a long run basis) reflects its actual capability.
The question should not be between Cuba and the DR, but rather between Haiti and Jamaica.
Supposedly, both share an IQ of 72; yet Jamaica is poorer than the DR by a mere $700 but surpasses Haiti by $6,100.
Of course, Jamaica is a very new country. It was only in the 1960s that it separated itself from what was left of the British Empire; and I believe it still belongs to the Commonwealth. Haiti has been 'free' for over 200 years of continuous decline. Haiti also lacks a real democratic values, a real capitalist system, and overall stability; unlike Jamaica.
So obviously IQ is not the end all be all, there are other factors that play into the equation. But, that still doesn't eliminate the possibility that IQ can explain certain deviations, once all other factors are equalized.
