In Coming Apart, Charles Murray estimates that there will always be 14 per cent of children in the top 5 per cent of the IQ distribution curve who are the offspring of parents with below-average IQs. Admittedly, that’s not much when you consider that the remaining 86 per cent will have parents with above-average IQs,
It really makes me wonder about the author IQ.
- plonh 11y agoWhy?
- brohee 11y agoBecause it's stupidly wrong. He misses the possibility for average people to have high IQ children. The sentence parses as : 14% high IQ children are from lower IQ couples, 0% are from average IQ couple, 86% are from high IQ couple... It also dismisses the existence of mismatched IQ couples, and highly intelligent men with a hot air head isn't unheard off, and nowadays women have their toy boys too...
- plonh 11y agoIn probability , the fraction of the population at exactly 50%ile is approximately 0.
- brohee 11y agoIt's prose. When you say someone is of average height, you usually mean within a standard deviation of average, not that the person is exactly the locale appropriate average height... At best that sentence is very poorly worded, at worst the author is a shining example of regression to the mean.
- lumpypua 11y ago> It also dismisses the existence of mismatched IQ couples Yep, IQ has a higher statistical variance in men than in women, basically guaranteeing that there will be couples with IQ mismatches, going both directions.
