Abstract
Background
The ability to accurately assess the intelligence of other persons finds its place in everyday social interaction and should have important evolutionary consequences.
Methodology/Principal Findings
We used static facial photographs of 40 men and 40 women to test the relationship between measured IQ, perceived intelligence, and facial shape. Both men and women were able to accurately evaluate the intelligence of men by viewing facial photographs. In addition to general intelligence, figural and fluid intelligence showed a significant relationship with perceived intelligence, but again, only in men. No relationship between perceived intelligence and IQ was found for women. We used geometric morphometrics to determine which facial traits are associated with the perception of intelligence, as well as with intelligence as measured by IQ testing. Faces that are perceived as highly intelligent are rather prolonged with a broader distance between the eyes, a larger nose, a slight upturn to the corners of the mouth, and a sharper, pointing, less rounded chin. By contrast, the perception of lower intelligence is associated with broader, more rounded faces with eyes closer to each other, a shorter nose, declining corners of the mouth, and a rounded and massive chin. By contrast, we found no correlation between morphological traits and real intelligence measured with IQ test, either in men or women.
Conclusions
These results suggest that a perceiver can accurately gauge the real intelligence of men, but not women, by viewing their faces in photographs; however, this estimation is possibly not based on facial shape. Our study revealed no relation between intelligence and either attractiveness or face shape.
PLOS one發表的論文，常人僅僅通過看陌生人照片，就可以比較準確地估計他的智商，但僅限於照片是男人。高智商臉的特征是臉較長，眼距較寬，大鼻子，嘴角上翹，下巴有棱角。低智商臉則相反，臉圓，眼距短，鼻子短，嘴角向下，下巴渾圓。
這些結果表明，一位觀察者可以通過查看照片中他們的臉而精確地衡量男人的真正智商，但不是女性。然而這種估計可能不是基於人臉的形狀。我們的研究顯示智商和吸引力或臉形之間沒有關係。
