I don’t understand? The second statement is a quote from wikipedia, and does not match my believes. It does not go into the nuance of what heritability entails, nor does it assign the large percentages which IQ advocates do. My believe can very well be:
It has been shown from biased studies that IQ has a large hereditary component, where these studies failed to account for genetic × environmental interaction and covariation.
By the way the wikipedia article it self goes into these nuances and caveats. Reading it, it is pretty clear that there may be a large inheritance factor to IQ, while at the same time large IQ differences between individuals have no genetic basis.
