Visualizations of shape regression on perceived intelligence in women illustrating shape differences between faces with attributed high intelligence and low intelligence compared to an average configuration in the middle."In both sexes, a narrower face with a thinner chin and a larger prolonged nose characterizes the predicted stereotype of high-intelligence, while a rather oval and broader face with a massive chin and a smallish nose characterizes the prediction of low-intelligence." as the study did not identify any key morphological traits that predict general intelligence.Though intelligence does not positively correlate with mental disorders or anomalies, there are some indications that extremely high intelligence combined with other factors such as creativity might carry a potential risk for various mental disorders –.” It would seem, then, that intelligence is not valued for its own sake, but as an adaptive trait conducive to reproduction and survival.
Kleisner sought to discover if there was a relationship between perceived and measured intelligence. Kleisner discovered that “both men and women were able to accurately evaluate the intelligence of men by viewing facial photographs.” But strangely, “no relationship between perceived intelligence and IQ was found for women.” Why would this be?
He also investigated whether there is an intelligent ‘look.’ In other words, are specific facial traits associated with attributed and actual intelligence? The study suggests that it may be beneficial for men to signal intelligence honestly.
On the other hand, a woman seeking a long term relationship could prefer a less intelligent but honest man, who compensates by long term provisioning, protection and a greater investment in childrearing." It is possible that for a man, honest signalling of intelligence, in conjunction with other cues, helps them to differentiate from male competitors.
If females are looking for different combinations of intelligence as signals of male parental investment, men may benefit from signalling traits that will appeal to at least some women, some of the time.
Very high intelligence could be genetically desirable, as it is associated with high status, greater wealth and resources.
However, as Kleisner indicates, very high intelligence may also be associated with poor social and emotional intelligence as well as low stability, earning potential and male parental investment.
The implication Kleisner draws is that the study participants, "accurately assessed intelligence from faces of men based on visual cues that simply are not explicable from shape variability in men's faces." Weird.
But still significant, especially in a world where images and perception counts for more than ever.
“Men with an IQ higher than 140 are perceived as relatively less intelligent (see Fig.
