The birthright

The eldest children in families tend to develop slightly higher I.Q.s than their younger siblings, researchers are reporting, based on a large study that could effectively settle more than a half-century of scientific debate about the relationship between I.Q. and birth order.
About three points. As the article ponits out, it’s a pretty general result — an average, not a prediction of what will happen in a given family — and, believe me, I am closely acquainted with one family where this does not seem to pan out at all. In short, interesting news, but be careful to whom you send the link!
