A spread of 16 IQ points?
Sorry, very hard to believe that is all nurture.
USA GDP Per Capita - $76,000
South Korea GDP Per Capita - $46,000
North Korea GDP Per Capita - $1,800
I wonder what the IQ spread would be if the other twin was raised in North Korea?

In NK, children have nutritional deficiencies which impacts IQ a lot. I met a woman from NK not too long ago. Very unfriendly, almost to the point of paranoia. Another SK I know confided in me that she had been raped so many times in NK that she had a fear of all men. Very sad.
