Human faces may hold more meaning for socially outgoing individuals than for their more introverted counterparts, a new study suggests.
The results show the brains of extroverts pay more attention to human faces than do introverts. In fact, introverts' brains didn't seem to distinguish between inanimate objects and human faces.
The findings might partly explain why extroverts are more motivated to seek the company of others than are introverts, or why a particularly shy person might rather hang out with a good book than a group of friends.
The study also adds weight to idea that underlying neural differences in people's brains contribute to their personality.
It seems mostly linked to sensory processing abnormalities/sensitivity. A small number of people go on to be creatively gifted etc and it keeps the neurotype around despite the downsides in modern society (but I suspect it will be selected out of the gene pool soon.)
The highly sensitive (HS) trait is a recently proposed human trait, found in up to 20 % of the population, which allows to process information deeper than usual. This trait makes HS people more prone to arousal, especially after exposure to sense stressors such as bright lights, loud noise, strong smells as well as dense and chaotic environments. This people may process, at the same time, larger amounts of sensory information than usual, making this trait an excellent model to pick up subtle environmental details and cues. However, they feel easily worn out, overwhelmed and exhausted because they sense every single detail while interacting with their environment.[3,4] To recover from such attainable sensory overload, these individuals require more quiet time daily to be alone, as well as additional longer sleep times than those without the HS trait.[3–5] Further, the HS trait correlates with higher perception, consciousness, inventiveness, imagination and creativity. Therefore, a relationship between higher sensory processing sensitivity, introversion, ectomorphism and creativity is proposed, which may have strong neurobiological and behavioral implications in developing rural areas, mostly in those under social conflict.
There are a number of disorders that have been created that are highly linked to this like the anxiety disorders, autism, schizophrenia spectrum, ADHD. All involve sensory processing abnormalities, hypo or hypermentalising and not differentiating adequately between objects and people. Leads to behaviour/outcomes like stimming, body focused repetitive behaviour (bfrbs,) hoarding, addiction/obsession, avoidance behaviour, objectophilia, zoophilia, attention/motivation problems, psychosis, creativity (from connecting abstract ideas together,) daydreaming, not tolerating change well, skinny nerds.
The only thing 'normies' if you will want to keep around is the cool idea/technological development part the rest freaks them out. I mean tbf to them on the one hand you get great artists/inventors and Einstein, but you also get Hitler and all the schizotypal serial killers (not the Ted Bundy's, normies get credit for that one and the basic psychopaths.)
