a norwegian study claims that firstborn sons have higher IQ than their younger brothers. they have discovered a difference of about 2.3 points:
"A study that used military draft records for more than 240,000 Norwegian men found that firstborns had an edge of 2.3 IQ points on their next oldest brothers, who in turn beat brothers born third by 1.1 points on average."
naturally, I refuse to believe that's true ;) so when a mail was sent out here at work asking for two brothers that wanted to refute or confirm the theory, I was quick to reply. we'll see how it goes!
