There are so many confounding variables here I don’t know where to begin, so I’ll just post the study, in the hope that it convinces somebody to eat some tofu or cheese instead of some ethically dubious meat:
Children with high IQs are more likely to be vegetarians when they grow up, according to research reported on Friday.
A British study of more them 8,000 men and women aged 30 whose IQs had been measured when they were 10, showed that the higher the IQ, the greater the odds of being a vegetarian.
“People who are more intelligent as children, who will obviously keep that intelligence when they are 30, were more likely to say they are vegetarians at that age than those that were less intelligent,” said Dr Catherine Gale, an epidemiologist at the University of Southampton in England.
She added the findings, which are published online by the British Medical Journal, were consistent with other studies showing people who are more intelligent tend to eat a healthier diet and exercise more.
PS. But don’t eat too much tofu, because then you’ll turn gay.
