Numbers – thank you for your post. My “genetic-superior” comment was short-hand for those who have pointed to studies connecting intelligence to genetics. I’m sorry for coming across like I was challenging smart people. I was trying to make the point that I don’t think the IQ difference between otherwise normal children is manifest in real life (except on an IQ test). My kids have different IQs (about 10 point difference ), but I can’t tell by their actions/decisions that one has a higher IQ than the other. So I was hoping to learn an example of “the discernible differences” when identifying a kid who demonstrates above normal IQ. In the example of athletes, one can appreciate differences in height/weight, strength and speed. There are also races and competitions to separate the truly elite from the average. IQ is different because it is not manifest in obvious ways, especially not in ways that cannot be attributed to other non-genetic factors. In short, I’m trying to ascertain how parents know their kid is so darn smart (if not for the IQ score).
Your link had very insightful info. Predictably, janitors are at one end of the spectrum and doctors are at the other. But still, janitors and doctors overlap in IQs. I tend to still think that, excepting the rare genius and the intellectually disabled, the rest of us live up to “normal.”
