I love your example! Way out of my depth here, but i do have a question:
The squirrel obviously has a genetic trait that causes it to have a small brain. We can tell its iq just by looking at it, without considering its DNA. Would the same logic apply, when there is no visual/physical trait present?
Can one brain cell be dumber than another? Could they be wired in a less optimal way?
Genetics likely explain the difference between a retard and a functioning human, but csn they also explain the difference between an iq of 100 and an iq of 105?
When people have this debate about intelligence, the inevitable political argument is that maybe, we as a society could invest more in ourselves, our children and our neighbours children.
The relevant question, perhaps, should be: how much impact could "nurture" have? Is somebody with an iq of 120 physically limited to become smarter? Or is that person already in the range, where the genes were all good?
I dont think anybody doubts that a retarded person has a genetic disadvantage. But does the same apply to an average human being?
And if that limit exist, is it a personal limit, or one you share with most other humans on this planet?
