There is a popular meme showing an IQ bell curve with dumb and smart people at left and right tail ends reaching the same conclusions about various topics.
The low iq character is a cavemanish brute, the high iq character is a cool, calm, collected looking stoic. Both use short, quick witted responses that defer to the metaphysical and immaterial to make a point.
The middle, the herd, is characterised with a weak looking herb visage, often shown crying, using hyper emotional verbal diarrhea making desperate appeals to science, group consensus, and faux morality.
I thought of this meme when hearing about an anecdote. Specifically, how humans make bad decisions and convince themselves that they are in the right.
Could sum up libertarians in a meme-intelligent people with high verbal IQ's justifying self destructive behavior.
Smart people have more in common with dumb people in some ways than they do with intelligent people.
