I don't know what the average IQ is in the Dominican Republic and how it breaks down along class lines. But a word of caution: in the DR you can't relate economic success to a high IQ, as many rich people are so as a result of corruption, nepotism, corruption, well, the whole sancocho. And some of the richest people I have met there are the most bankrupt people, morally, ethically and culturally, that I have ever met in any place. When I used to spend summers in Jarabacoa with my aunt I was always so impressed by the peasants there. I was impressed by how Ramona, my aunts cook, had what it took to run a household without a father, feed nine kids, send them to school, participate in her church and most impressively, not be bitter or complain about the hand she had been dealt. Millions of Dominicans are like Ramona. They may not be good at answering logic questions or putting pieces of triangles together. But she is campo smart, does what she needs to do to keep her family together and offer her kids a better future. Wow, what a concept. If only all the smart people had such values!
