IQ in childhood and vegetarianism in adulthood: 1970 British cohort study

I read your article with interest!

I think the findings can be explained in a variety of ways as
suggested previously. Higher intelligence, means a push for a healthier
lifestyle. But perhaps also a deeper contemplation of the ethics of
killing animals for food?

Perhaps people with higher IQ's are more likely to contemplate on
spirituality, animal rights, world economics (it's more expensive to raise
a pig than grow crops)to make their life-style choices?
