This Didn't Happen in Our Family

Boys at the top of the pecking order score higher on IQ tests than their younger brothers.

It's a matter of what they call social rank in the family -- the highest scores were racked up by the senior boy.

The average IQ of first-born men was 103.2, they found.

Second-born men averaged 101.2.

And for third-borns, the average was 100.0.

Because of some cases in which an older sibling died in infancy, the child who was raised as the eldest had the higher IQ than the rest of the group in his pecking order. That led researchers to conclude that it's not a matter of being born first, but how you are treated when growing up the eldest boy.

This study did not include women which is good because I do not want Poop On Me to get mad. But me versus the Master? It's not even close.
