Abstract
In the last chapter we found 69% of variation to be due to genetic influences and only 31% to environmental ones. Clearly, genetic factors outweight environmental factors in causing the wide range of intellectual ability found in human populations.
Men who have excessive faith in their theories are not only ill prepared for making discoveries; they also make poor observations. Claude Bernard
