...quality of the concerts, not the number. At least that's what mother always used to say between gulps of the Jim Beam that she kept next to her Random Thoughts notebook. And this week features the two biggies in back to back performances. HRO on Friday followed by the Bach Society on Saturday. Mother would have been so happy...
...heritability of I.Q. are estimates of the heritability within social classes, and indeed within families to a very large extent. In no case ever reported is there an estimate of heritability that can be referred to the whole white population of the United States, or to any large random sample of persons spanning a representative spectrum of social classes or environments. The reasons for this is that estimates of heritability in human populations must make use of the resemblances between relatives. But relatives share both genes and social environment, so great emphasis has been put on the resemblances and differences...
...problem is even deeper than that. Suppose it were possible to distribute identical twins or foster children completely at random across social class lines. An estimate of heritability based on such data would still not tell us anything about the cause of differences among classes. Imagine that the heritability of I.Q. performance were very high within classes, let it be 100 per cent, but that all differences between social classes were the result of social arrangements. Even in such an extreme case, there would be a high correlation between children and their biological parents and the heritability estimated would...
