First Born Kids really ARE Smarter

Birth order might also affect a child's personality and intelligence, according to a new study. First-borns are typically smarter, although younger siblings get better grades and are more outgoing.

The results lend support to previous hypotheses, such as the eldest sibling tending to have higher aptitude. But they also contradict other proposed ideas, such as first-borns tending to be more extroverted.

According to MSNBC:

“In the current study, [researchers] surveyed 90 pairs of siblings in high school. Subjects were asked to report their grades and rank themselves as compared with their siblings on intelligence, work ethic and academic performance. The researchers also obtained academic tests scores and grades ... While the first-born tended to do better on measures of intelligence, the younger siblings had higher overall grade point averages.”
