...thing, science has no agreed-upon definition of "race": however you slice up the population, the categories look pretty arbitrary. For another, science has no agreed-upon definition of "intelligence" either - let alone an agreed-upon method to test it. All kinds of cultural biases have been identified in IQ tests, for example. If there is something fundamental in our brains that regulates our capacity to learn, we have yet to separate its effects from the effects of everything that we experience after we're born...
...been known-or at least suspected-for years. But increasingly, there's hard evidence of its impact. In June, for example, a group of Norwegian researchers released a study showing that firstborns are generally smarter than any siblings who come along later, enjoying on average a three-point IQ advantage over the next eldest-probably a result of the intellectual boost that comes from mentoring younger siblings and helping them in day-to-day tasks. The second child, in turn, is a point ahead of the third. While three points might not seem like much, the effect can be enormous...
...latitude given the last. Middle children are expected to step up to the plate when the eldest child goes off to school or in some other way drops out of the picture-and generally serve when called. The Norwegian intelligence study showed that when firstborns die, the IQ of second-borns actually rises a bit, a sign that they're performing the hard mentoring work that goes along with...
...siblings in a family can also trump birth order. The 1% income difference that Black detected from child to child tends to flatten out as you move down the age line, with a smaller earnings gap between a third and fourth child than between a second and third. The IQ-boosting power of tutoring, meanwhile, may actually have less influence in small families, with parents of just two or three kids doing most of the teaching, than in the six- or eight-child family, in which the eldest sibs have to pitch in more. Since the Norwegian IQ study rests...
...Sharon Stone has a Mensa level IQ. She is also an ordained minister in the Universal Life Church, as well as a Buddhist and a Scientologist. I am not saying that being a member of three churches makes you insane, but perhaps it makes you prone to crazy pants with appliqué on them (Sharon seems to love these. I can’t even tell you how many times I open a magazine to see Sharon Stone running an errand in appliqué pants. It is insane). This is not to say that Miss Stone doesn?...
