The bad news is that not only has it been scientifically measured that the English are getting stupider, after about 30,000 years of steady progress from the simple use of tools in Kent chalk pits up until David Blunkett took over at the Ministry of Edukashun, Edukashun, Edukashun. Since when...
A study in 2009 led by James Flynn himself and published in Economics & Human Biology compared IQ scores obtained by British teenagers in 1980 and 2008, using the same test. The average had declined by two points on average, but by as much as six points among teenagers in the top half of the IQ scale… a six-point decline in IQ would equate with a 0.3 per cent fall in GDP.[From Received wisdom | Prospect Magazine]
It's the second point that's even more disturbing than the first. In the olden times, stupid people could contribute to the economy by farming and such like, but those days are over. We now have an economy where stupid people are unemployable, and that's a real problem for society. I suspect when we look back on this era from the perspective of the distant future we will be genuinely perplexed about the "design" of society. A welfare state that's gone horribly wrong -- leading to an overproduction of stupid people -- and an education system optimised for jobs that vanished a generation ago. There's probably no way back -- the English will vanish like the Easter Islanders, having created an environment that cannot support them -- but we may be able to launch a rearguard action if we take immediate steps. I don't know what these might be -- it's hard to think of ways to reduce the number of stupid people without veering into eugenics -- but one place to start might be to stop stupid people from voting. The political process is undermined by stupidity as it is, and as the population continues to get stupider than state actions will become further deranged.
One defence worth considering is immediate action to reduce the size of the state, so that there are fewer aspects of society for it be deranged about. If sectors such as health and education were not run by the government it would be much more difficult for stupid people to obtain control of them, and this would be much to our benefit I'm sure.
