baftan,
If two people with high IQs have children there is a tendency for such children to also have high IQs. Similarly for parents with artistic abilities. I have three daughters all now in their twenties. They were all raised in the same environment and the same schools. They each demonstrated very different behavioral characteristics from as early as a few weeks and which have stayed with them for life, hardly the results of environment or conditioning. Clearly behavioral genetics is real and I would argue quite obvious when observing similar traits with family groups and where offspring mix freely with others. Traits such as good with math, or creative writing, or analysis, are all such examples, as compared to many who may have enormous trouble with these tasks despite advantageous environments, but may excel at games/sports (e.g. good 3D visualization), or art. All of these things and the other examples are cerebral characteristics that are clearly genetically influenced. It is not a big step to include the abilities to deduce and analyze clearly among such traits, others we know despite the very best of teaching cannot easily analyze or produce good math - they are simply not genetically inclined to do so. But this is obvious, surely?There is no such genetics independent of environment and conditioning. This is an unsubstantiated assumption.
