rule #1: be kind
the researchers note that the sister raised in the US had suffered three previous concussions

the twin raised in Korea described growing up in a loving and harmonious family home, the adopted sister reported a harsher upbringing, colored by regular conflict and the divorce of her adoptive parents
It does seem as if there would be explanations for the unusual difference.
That's kind of an understatement. Three traumatic brain injuries is not exactly something that can be ignored when discussing differences in mental faculties.
Was the one raised in the U.S. around lead at some point?
iq still a thing?
Apparently not in the US!
Yes. Contrary to current pop-sci thought, it's not actually useless bunk. Epically when differences reach into 2 digits.
I didn't realise it wasn't a thing anymore.
I know it's never been a good indicator of success or even cognitive abilities but it's still a thing that people try to measure.
It still is a thing, always will be. People are vastly differently skilled. The problem isnt that there are different abilities but that our centralized meat mill pushes them into categories. It doesnt make you better to have more skill in one area, it just means people should consider listening to you.
The sister raised in the US had an IQ 16 points lower than her sibling in Korea. Previous studies revealed that identical twins typically have no more than a 7-point IQ difference, making this case astounding.
@fne8w2ah environment shapes our behavior.
Yes, but, IQ isn't expected to be that much influenced by behavior.
