The question is: are people stupid because they are smoking or are they smoking because they are stupid. From the press release, it does not seem that they took any measures to establish causation (like comparing IQ tests from the time before people started smoking). I would wager that people with higher cognitive abilities might be more amenable to the advice of their doctors. |

I would argue that culture is a better root cause causal explanation, with stupidity and smoking both being consequences of that (though each with their own causal influence to some degree).
