What exactly is intelligence? There aren't any easy answers. Despite the progress that has been made

in genetics and psychology, human intelligence has remained one of the most controversial areas of

modern science,until now, that is, for the discovery of a gene (基因) linked to intelligence has made the

experts think again.

Robert Plomin of the Institute of Psychiatry in London and his colleagues in the US have been looking

into genetic make-up. From their research, they have discovered that a slightly different gene is more

common in those with a high IQ. Plomin analyzed DNA from two groups of 51 children aged between 6

and 15. What he found was that the first group had an IQ of 136, putting them in the top 5% of the

population, while the other group had an average IQ of 103. An analysis of their genes showed that 32%

of children in the higher group had the gene in question, while only 16% in the second group did.

However, there is a lot more research to be done, and Plomin himself is cautious at this early stage. He

suggests that there are probably many genes that contribute to intelligence, rather than just one.

Several studies have shown a strong link between IQ and career success, although some

psychologists remain unconvinced about this. Professor Michael Rowe, who has written a book called

Genius Explained, is one of these. "The people with the highest IQs are not usually the ones who do

best in their careers."

Many psychologists now believe that when it comes to intelligence, IQ isn't everything. Many

alternative views have been put forward recently. One example is the idea of multiple intelligences, which

was developed in the 1980s by Harvard psychologist Howard Gardner. This offers a much broader

view than the IQ theory, including creativity and communication skills as relevant factors(因素) in

intelligence.

Tony Buzan, brain expert and author of Master your Memory, is enthusiastic about this belief, arguing

that true geniuses(天才) do indeed appear to combine high levels of each type of intelligence. He lists

Alexander the Great, Pablo Picasso and Albert Einstein as examples. At the same time, Buzan believes

that everyone can develop their intelligence, only if they take the trouble to exercise their brain. Perhaps

there's hope for us all!
