Clearly you misunderstand what "hereditary" means, as I clearly meant that there is no evidence that the difference between groups can be explained by environmental means. If you don't understand the difference between that statement and saying that IQ isn't hereditary then you should just go.
Copy and Pasted for you...
Heritability is informative about the nature of between-group differences
comes in two forms, and in both cases height and IQ in human populations are good examples. The
first misconception is that when the heritability is high, groups that differ greatly in the mean of the trait in question must
do so because of genetic differences. The second misconception is that the observation of a shift in the mean of a
character over time (when we can discount changes in gene frequencies) for a trait with high heritability is a paradox. For
IQ, a large increase in the mean has been observed in numerous populations, and this phenomenon is called the Flynn
effect, after its discoverer
. The problem with this suggested paradox is that heritability should not be used to make
predictions about mean changes in the population over time or about differences between groups, because in each
individual calculation the heritability is defined for a particular population and says nothing about environments in other
populations. White males born in the United States were the tallest in the world in the mid-19th century and about 9 cm
taller than Dutch males
. At the end of the 20th century, although the height of males in the United States had
increased, many European countries had overtaken them and Dutch males are now approximately 5 cm taller than white
, a trend that is likely to be environmental rather than genetic in origin.
What annoys me that you know the evidence is not conclusive that there is a genetic role. But we do know that people from different countries/races live in different environments- and we know that culture affects cognition. Therefore there is no need to assert that there is a genetic basis, (indeed there could be!!!), but until we do know it seems just as likely that caucasians are LESS intelligent than other races- WE SIMPLY DON'T KNOW.
