Science has few more controversial topics than human intelligence—in particular, whether variations in it are a result of nature or nurture, and especially whether such variations differ between the sexes. The mines in this field can blow up an entire career, as Larry Summers found out in 2005 when he spoke of the hypothesis that the mathematical aptitude needed for physics and engineering, as well as for maths itself, is innately rarer in women than in men. He resigned as president of Harvard University shortly afterwards.
It is bold, therefore, of Jonathan Wai, Martha Putallaz and Matthew Makel, of Duke University in North Carolina, to enter the argument with a paper that addresses both questions. In this paper, they describe how they sifted through nearly three decades of standardised tests administered to American high-school students to see what had been happening to the country’s brightest sparks. They draw two conclusions. One is that a phenomenon called the Flynn effect applies in particular to the brightest of the bright. The other is that part, but not all, of the historic difference between the brainiest men and women has vanished.
The three researchers drew their data from Duke University’s Talent Identification Programme, TIP, which is designed to discover especially clever candidates early on: all the participants had scored in the top 5% of ability when confronted with exams designed for much older students. TIP, in turn, draws on three national exams: SAT, EXPLORE and ACT.
In the early 1980s, the ratio of males to females in the top 0.01% of maths scores in SAT, the Scholastic Aptitude Test, was around 13 to 1. By the early 1990s, it had fallen to four to one. After this, however, it remained unaltered.
It is clear that the rise itself must be "nurture" of some sort, but the subsequent stasis could have either explanation. A line of reasoning in favour of "nature" is that put forward by Simon Baron-Cohen, a psychologist at Cambridge University. This connects the extreme systematising patterns of thought which make a good mathematician with the advantage of men among those with Asperger’s syndrome, a form of autism that does not harm a person’s general intelligence. But the difference could equally well be the result of some as-yet-unclear difference between the ways girls and boys are brought up.
That such unclear environmental influences can have real effects on IQ is eloquently illustrated by the Flynn effect. This phenomenon, brought to the world’s attention in the 1980s by James Flynn of the University of Otago, in New Zealand, is that average IQs around the world have been rising at the rate of 0.3 points a year for the past eight decades. Using the TIP data, Dr Wai and his colleagues showed that this is as true of the brightest youngsters in American society as it is of lesser mortals, suggesting that even they can have their abilities boosted by whatever is causing the Flynn effect. Once again, the changes seem to be mainly in mathematics. Scores in the brightest children’s verbal-reasoning and reading abilities demonstrate no clear trend, but all three national tests show sustained improvements in their mathematical ability over the past three decades.
[A] aims to find out extraordinarily smart people based on three exams in America.
[B] shows, with colleagues, that general IQs of the cleverest youngsters have been rising.
[C] assumes that genetically, there is an inequality in mathematical ability between sexes.
[D] presents that there are some relationships between intelligence and Asperger’s syndrome.
[E] shows that IQ has been rising on average under environmental influences.
[F] finds an inequality in mathematical ability between sexes according to his research.
[G] concludes, with his colleagues, that intelligent difference between sexes doesn’t change.

选项
答案
D
解析
Simon Baron-Cohen出现在第五段。该段提到Simon Baron-Cohen提出的一个理论,该理论把高度系统化的思考方式(成为好数学家必备的)与艾斯伯格综合症患者在数学上的优势联系了起来。可以看出.智力与艾斯伯格综合症有关联。D表达的正是这个意思,其中relationships、intelligence分别对应原文的connects、extreme systematising patterns of though,而Asperger’s syndrome是原词复现,故确定D为答案。
