Nurture and environment is something I have ALWAYS gone on about whence me being known as a single mother Crusader often in an unfairly negative light despite me never putting kids at risk. I want good outcomes, not kids suffering from the fall out of irresponsible adults who don't need to inflict their behavior onto children.

In saying that, with IQ genetics is unfortunately likely a significant factor. I have jokingly said the solution is to marry East Asians, but that is a little bit naughty. Others argue this is less of a factor though. I can only go on what I read.

I get no fun from IQ and get that my cat has a low IQ, but I love her all the same.
