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 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 fi rst 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 intelligence, 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 in intelligence.
