I knew it 😉
A larger orbital prefrontal cortex, an area of the brain associated with decision-making and cognitive processing, has been shown to correlate with greater social skills, according to a study by a team of UK researchers. Among the scientists was Robin Dunbar, who pioneered the idea that the average human is limited to a social circle of about 150 people, a constant now known as the Dunbar number.
The study looked at “intentionality,” summarized in the paper as, “the ability to explain and predict the behaviour of others by attributing to them intentions and mental states.” It’s a measure of social skill.
A study in 2010 also found:
individuals with larger amygdalas (an area of the brain usually associated with fear and other emotions) have more friends and more complex social networks. Magnetic resonance imaging scans found a positive link between big amygdalas and the richest social lives. Professor Lisa Barrett, a psychologist at Northeastern University in Boston, Massachusetts, reported the findings in the journal Nature Neuroscience.
Roger Dooley (@rogerdooley) gives a good summary:
I don’t really expect hiring managers to start scanning the brains of job candidates, but the study does confirm what we already know from experience: some people have inherently better social skills than others, and that training alone may not be enough to close this gap.
