Does low intelligence(IQ) mean less suffering?
I can see how an argument might be constructed that people of higher socio-economic status might be prone to contempt for people of lower socio-economic status and, given that we live in a highly specialized industrial civilisation where a particular type of cognitive functioning is highly rewarded, then the concentration of higher socio-economic people who posses this kind of trait might be prone to contempt as as self reinforcing group behaviour. However, I think this may have more do with their socio-economic position than it has to do with their IQ per-se.
