Becuase from a scientific perspective, that's the case. Your thesis(which claims that I am lying) completely ignores factors like malnutrition and lack of education(among others) that directly affect IQ measurements.  It is blatantly obvious that these factors are playing a part in the measure you're seeing. If you can't see this factor(it's right in front of you), then dare I say that you would have absolutely no business making claims about people other than yourself possessing a low intelligence quotient. That's not scientific at all it's just excuses ;)    Let's do an imagination exercise... we go back 250,000 years ago to the supposed start of the modern human being...    Prehistorical periods 242,000 BC - 6000 BC  * The Stone Age  * The Copper Age  * The Bronze Age  * The Iron Age    Historical periods 6000 BC - Present  * Antiquity  * Middle Ages (Europe, 5th century - 15th century)  * Early Modern (Europe, 14th century - 18th century)  -Age of Discovery (or Exploration) (Europe, 15th century - 17th century)  * Modern (Europe, 18th century - 20th century)  -Information Age (1971 - Present)    So about 500 years ago whites were in the early modern period in the age of discovery and blacks were where? stone age? that's right!    Now till this point you don't have black's excuse of choice that the evil white man with his evil white colonialism was holding them down, do you?     or weren't those 249,500 years enough time for black to develop a decent civilization?     500 years later where we are now?  whites -> Information Age  blacks -> STILL in stone age :rolleyes:    The point is IF the environment influence is significantly then is still your fault since you and only you haven't been able to create a better environment around yourselves.     If blacks (as a whole population) improved their level of comittment to education, they'd probably do just a tad bit better in school.  This is just another blatantly obvious fact. When you adhere to a modern culture that devalues education and values criminality, you're going to end up with some negatives. correction the modern culture :rolleyes: that devalues education and values criminality is black culture, once again is your people creating a negative environment that affects yourselves...     From a purely biological standpoint, blacks are fully capable of achieving IQ measures reaching as high as the low to mid 90's. The studies I have cited earlier in this thread establish this conclusively(blacks in britain with very little admixture still pull off measures only 8 points below those of whites, who stand at about 100 in England).   The portuguese IQ measures average right at around that level.  With that in mind, it can be said that the portuguese are in no way superior to blacks. The same can be said about many others groups of people that are commonly labelled as superior to blacks. I doubt that... Portugal is literally ages away from African countries...    If black were superior to Portuguese :rolleyes: how come Africans didn't 500 years ago came with their ships to discover Portugal instead? Oh sorry, Africans didn't had ships 500 ago, nor ever, since ship is not a discovery from the stone age...     I am very confident that I am more well versed with regards to the history of those lusophonian nations than you are. I also know that when the portuguese left Angola and Mozambique, they left almost ZERO infrastructure. The Africans who had been there were, of course, living under a white-ruled system. They did not have the same access to the education, etc, etc, that portuguese colonialsm had possessed. When the colonials left, they took all of their knowledge(which they had not passed on to their subjects) and left the nation with just about nothing.  Of course, then there were the two cold war proxy wars fought in the territory of both these nations. These nations had no control over that.  Cape Verde today is doing just fine-it doesn't belong in the same list alongside the other two you mentioned. Portugal is well known to have left more infrastructure than the other colonial powers, they did left infrastructure the thing is the savage blacks destroyed it after driving the Portuguese away from their farms (or should I say fazendas ;))    The Portuguese were the ones with access to education while the poor black were deprived of it, the Portuguese left and took the knowledge with them leaving the country with nothing to start off they had NOTHING when the Portuguese first came in, the portuguese education was theirs, as it was their knowledge, their tech... why should they share it? why if the blacks are biologically equal to Portuguese in term of IQ and if the portuguese are in no way superior to blacks, didn't blacks have their own education, technology and knowledge?    The Portuguese didn't left they were drove away by blacks.    To be fair every colonial nation was left with more than they have ever had or imagined.    And Cabo Verde is just another third world hole. :rolleyes:
