Question

Quizplus · Accepted Answer

Being raised in a highly stimulating environment appears to have the greatest positive impact on the IQs of children. This includes exposure to a variety of educational and cultural experiences, access to books and learning materials, and engagement in intellectual activities. Both biological and adoptive parents' IQs may have some influence, but studies show that environmental factors have a stronger impact. Being raised in a passive environment, on the other hand, may limit intellectual development and have a negative impact on IQ.
