alt Hacker NewsBlank slate theory has been thoroughly discredited so many times I'm not sure why I'm even responding, but this is complete nonsense. If you're born with 62 IQ like the average Sierra Leone citizen, no amount of education will get you to 120. It's literally not possible.
According to research, a full education can add ~15 IQ points.
So someone from Sierra Leone who's average and receives a full education can expect to have around 77 IQ, which means severe issues with reading comprehension, math beyond simple arithmetic and following multi-step instructions.
so geographical region of birth dictates intelligence? how intriguing.
i would like to know if that child was fed well, provided with shelter and given a good education -- would it still be, in your words, "not possible" for them to break even 100IQ?
