Yes, that's a real problem, but Stuart didn't actually mention studies of identical twins raised apart, probably because they are rare. He mentioned two types, adoption studies and twin studies, not (twin adoption) studies. Examples: comparing siblings raised apart for the one, and comparing identical twins to their siblings for the other.
