Firstborns smarter than younger siblings

GradCatFirstborn children are smarter than their younger brothers and sisters, according to a Norwegian study published in Science. In families with two or more children, the IQ of the oldest child is, on average, two points higher than that of the second child (103.2 versus 101.2). Children with two older siblings score an average of 100 points on an IQ test. The scientists who performed the study think that the elder children get an intelligence boost from helping and caring for their younger kin.

In other news, an American couple seems to have fallen off a roof while having sex. A taxi driver found them dead and naked, and a quick search revealed their clothes on the roof of a nearby building. They must both have had a lot of older brothers and sisters.
