Boris Johnson, the London mayor, got into hot water last week when he praised the value of greed as a spur to progress and controversially suggested some people struggle to get on in life because of their low IQs.
No, it says, there is no evidence that the leisured class have higher IQs than people who work for a living.The letter can be read easily by touching the right spot on a screen by the display case.
Though the Chinese and Japanese don't have higher average IQs than Westerners, they are better at maths and have no tradition of taking long holidays.The most uplifting chapter in the book is about a chain of publicly funded American schools called KIPP (Knowledge is Power Programme) that began operating in tough inner-city areas just over a decade ago.
As the price of petrol soars, fuel-sipping Japanese cars would normally zoom past rivals, but drivers won't buy what the makers don't make.The shortage of parts has delayed the launch of several models, such as Toyota's iQ microcar and Prius V, plus Honda's 2012 Civic and its CR-V (a cross between a sports-utility vehicle and a sedan).
Studies in Texas and Colorado found that children adopted by high-IQ families were no smarter than those adopted by average families.
If, as some scientists now believe, those nine months are important in deciding how the brain is wired, this would help to explain why non-identical twins, who are no more genetically alike than any brother and sister, have IQs more like each other's than ordinary siblings do.
Toyota and Nissan have told their American dealers that deliveries of cars will not be back to normal until July at best, maybe September.At this late date Honda cannot postpone the Civic's launch, as Toyota has done with several models, including the new Prius V hybrid and the American version of its iQ minicar.
Irregular bedtimes left their IQs about six points below those of their contemporaries at the age of three.
The latest, third-generation Prius and the brilliant little iQ city car show what they are capable of.
Even Warren Hill, a man with an IQ of 70 who is diagnosed as mentally retarded by every doctor who has examined him, found it impossible to meet this standard of proof".
For blood pressure it seems obvious that inheritance within groups is irrelevant to divergence between them; for IQ there is a curious readiness to accept that such differences are due to genes.
