IQ was assessed by tests of mental ability at age 10 years and vegetarianism was self-reported at the age of 30 years. The findings remained statistically significant after adjustment for social class (both in childhood and later), academic or vocational qualifications, and sex. So clever children are more likely to become vegetarians, rather than vegetarians being more likely to become clever.
