How your personality is influenced by your physical appearance

| | July 1, 2019

Known as “facultative personality calibration”, this is the idea that our personalities develop in a way that best suits the other genetic cards we’ve been dealt, including our size, strength, and attractiveness.

Evidence supporting facultative personality calibration is growing – not only in terms of how one’s looks influence our personality traits, but even our approaches to finding romantic partners and our political beliefs. (It’s worth noting that the theory remains tentative thanks to a dependence so far on mostly correlational and inconsistent data, and because there are alternative explanations for the findings, such as that our personality traits can shape our bodies).

Consider trait extroversion, which involves not only being more sociable, but also more adventurous and willing to take risks. In evolution, it would make strategic sense if stronger, more physically capable people exploited their bodily advantages by being more extroverted.

That’s exactly what some research has found. One study out of Germany’s University of Göttingen recently reported that of more than 200 men, those who were physically stronger and who had more “macho” bodies – including larger chests and biceps – also tended to be more extroverted, especially in the sense of being more assertive and physically active.
