Frankly, I think you are giving to much credence to IQ. We know that the upper ends of IQ tests occur more frequently than they should statistically. We also know there are many extraordinary thinkers with pretty normal IQ's (Feynman for example). I think executive function and some factors that we are currently not able to measure have more to do with success than IQ scores. I have a DYS daughter. However, she has exceptional EF and these two things do not seem to correlate necessarily. I think that it is the EF that make the IQ work for her and not the other way around. In her case she did not learn it from me (although her dad has great EF) so I think much of it may be genetic and is just a natural way of processing the world.
