So we had the Sutton Trust report.
Parental background continues to exert a very significant influence on the academic
progress of children:
o Those from the poorest fifth of households but in the brightest group at age three
drop from the 88th percentile on cognitive tests at age three to the 65th percentile
at age five. Those from the richest households who are least able at age three
move up from the 15th percentile to the 45th percentile by age five.
o If this trend were to continue, the children from affluent backgrounds who are
doing poorly at age three would be likely to overtake the poorer but initially bright
children in test scores by age seven.
o Inequalities in degree acquisition meanwhile persist across different income
groups. While 44 per cent of young people from the richest 20 per cent of
households acquired a degree in 2002, only 10 per cent from the poorest 20 per
cent of households did so.
But we\’ve also got this:
The problem with this famous Eyferth study, which formed the backbone of Flynn\’s Race, IQ, and Jensen, is that it was a study of children. So? After Flynn wrote this book, behavioral geneticists gradually made the amazing discovery that the heritability of IQ (and many other traits) sharply rises as children grow up, while family effects on IQ fade out.
Now I have no idea whether that last is in fact true, but if it is it provides us with a way of interpreting the Sutton Trust\’s results. A way that will be most un politically correct. Children of the poor do badly in the educational system because they are dim. That dimness being a genetic problem, one which becomes apparent as they age.
It is, in fact, the exact opposite of the Trust\’s thrust. It isn\’t that a bad environment hampers the children of the poor, it\’s that we only find out about their dimness as they grow older.
No, I don\’t think I like that conclusion either but what if it is actually true?
What if, say, the educational mobility of the 50s through 70s was a one off event? That there were those with the brains but not the opportunity to rise, that once the opportunity arose they did in fact rise but that there\’s no more such to come?
All depends rather on the heritability of IQ I guess and that\’s something that creates a firestorm whenever it\’s mentioned.
As I say, I\’m not sure I like that conclusion but I\’m absolutely certain that it will enrage all of the right people.
