Does birth order impact personality? New Study Says No.

The Boston Globe reports:

To what degree does birth order influence one’s personality and odds of success? Are firstborns really more conscientious and perfectionistic, while the babies of the family are more free-spirited and sociable?

A recent study from the University of Illinois at Urbana-Champaign confirmed there are indeed differences in personality and IQ associated with birth order, but found that the differences are so small as to have no practical impact. The findings appeared in the Journal of Research in Personality.

An interesting article.
