Intelligent people have ‘unnatural’ preferences and values that are novel in human evolution
An earlier study by Kanazawa found that more intelligent individuals were more nocturnal, waking up and staying up later than less intelligent individuals. Because our ancestors lacked artificial light, they tended to wake up shortly before dawn and go to sleep shortly after dusk. Being nocturnal is evolutionarily novel.
