Born will know better than me,but wasn't there a study done on a global scale ,(funded by those intent on proving we 're all equal )measuring IQ and comparing racial results,..it turned out that ashkran ( spelling ) jews ,were miles above any other racial group ,followed by east Asians ( oriental ) and then Caucasians ,...with sub Saharan African s and Albanians being the bottom groups .seem to remember reading this somewhere .
