I'm not by any stretch pro-life, but to mention again the whole "fetus IQ" thing...
My son has FASD. I can't really say if anyone was aware of this before his birth as no one I know was personally aware of the circumstances leading to his birth, but let's say for sake of argument that it was known pre-birth. He came into my care when he was 4, and he did not have the ability to count to ten, recognize letters, say the alphabet, basically, on any testable level of intelligence he was well behind.
Now, at 9, he's in the advanced level of fourth grade. So, biologically and early development wise, you'd think this would be a kid that was on the low end, but it just shows how much environment matters.
