Idaho said:There have been a fair number of studies which compare test results of children compared to their parents - both biological and adoptive. The suggestion from these studies are that in the earlier years - pre-teen, the correlation with the biological parents measured intelligence (with all it's caveats) is very strong.
There also seems to be a suggestion that post-teen the adoptive parents can have a certain amount of influence.
