First-born child has higher I.Q.?

The results are in.
I just found out that, unless I am not the norm (which my parents/friends and pretty much everyone I have come in contact with tell me often), my brother probably has a higher I.Q. that I do!

Researchers are now reporting there is a correlation between I.Q. and birth order. While the difference is minimal, three points on average, the eldest child in the family tends to develop higher I.Q.’s than their siblings. What’s even more interesting is that this finding has nothing to do with biology or the child’s prenatal environment but with family dynamics.

Maybe it’s because I am the middle child, but is this truly a shocking “finding?” Think about it.

As the FIRST born, leadership is a role that is almost forced upon a child in this position. Out of the shear notion that respect has been given, they are willing and eager to accept. They are a novelty! The first born is a celebrated and cherished event, anything after that has already been done before. The first born receives the parent’s undivided attention. When parents later on have to juggle multiple kid’s activities, school, feeding, etc. it’s natural that their intellectual environment will be decreased amidst all the madness. Sounds like your classic case of natural selection because at a young age, one’s intelligence is their most redeeming quality. After the first born assumes responsibility, leadership and intellect… what ever roles are left for the others will gladly be assumed in an effort to stand out and be someone to their parents.

While I still stand strong on MY position that I am more intelligent than my brother…at least he has an argument now.

What's your take on these "findings?"
