First-born get the brains.

Don't tell my younger sister (because I'm going to the second I post this), but according to a new study, the first-born in a family has, on average, a 2.3 point  higher IQ than their younger sibling. 2.3 points supposedly amounts to a 30% increase in the chances of getting into an Ivy League university.

Do they do these studies just for people like me to blog about?
