We have a lot more than five senses...

Close your eyes and clap your hands, now how did you just do that?

Proprioception is a sense of where our body parts are in relation to each other, and how we can walk without staring at our feet the whole time.

What you're looking for is a "gut feeling" which is often your subconscious, but your gut has a shitton of neural cells too. And can function like a "minibrain".

Most likely it's an actual "proto-brain" hold over from before organisms even had heads.

But anyways, most likely it's coming from your subconscious, there are things it puts together and recognizes, and especially if danger is around then it's just gonna flash a warning light and not walk your conscious mind thru the logic that tells you why there's a warning light. Because it's better to respond fast and later work out why the warning light was flashing.

So, an example would be before I learned about the correlations between prenatal testosterone, in group bonding, and facial width; it was a joke among a specific friend group that "don't trust guys with skinny faces".

Not that low prenatal testorone makes someone untrustworthy, just that in situations where you need to 100% count on people to have your back, the people most likely to not are the ones that are not biologically wired to blindly defend what they recognize as "us", their in group.

But this is a thing on a wider social scale, guys with "rat face" are often cast as villains and betrayers in media, because on some level even tho we consciously don't recognize why, we all just instantly distrust to some extent. Not from conscious logic, but individual lifetimes of experience and us just automatically picking up the pattern.

Prenatal androgen exposure, approximated via 2D:4D, was associated with prosocial behavior. In contrast to previous research in older children, higher exposure was related to stronger prosocial tendencies, which corresponds to earlier findings on fairness in adults. Our findings point towards a potential role of sex steroids in the early development of children's social behavior, but they have to be interpreted with caution due to the small sample size of the current study. Nevertheless, they underscore the importance of integrating biological and psychological perspectives, while also highlighting the significance of studying the development of prosocial behavior within peer groups.
