If intuitively you don't like the "vibe" of someone, that's all the reason you need not to associate with them. As long as it is actual intuition and not hormones, trauma or general neuroticism erroneously spiritualised as intuition, which is an all too common occurrence.

Spiritualising defective biology as supernatural insight is a category error, leading to poor and sloppy decision making, and is just overall generally inaccurate, no matter how right it feels in the moment.

Trauma especially as a nervous system state completely hijacks the mind into an entirely different perceptual orientation, with very transient, but powerfully held beliefs that seem like perfect truth in the visceral acuteness of the moment, when it is in fact "just the trauma talking" - to spiritualise this: it is to be possessed in a way that induces terror.

Smart but otherwise foolish men will then generally scoff at the idea of "vibes" as a legitimate metric of anything for precisely all of the above reasons, but also overcorrect to invalidate the the legitimate use case: actual intuition.

But as with any group unreceptive to certain demonstrably useful ideas, it's not really the concept they have a problem with, but how it's presented and the implications of that, and thus the framing. So to translate it into a way they would appreciate: if whilst your subconscious internally models a person it pattern detects an overlapping correlate stack of known threat and disgust cues which aren't potent enough to trigger revulsion, but are numerous enough to urge distrust, you will feel a vague sense of discomfort, disdain or disgust.

Now you can spend time trying to consciously explore "why I feel this way", but such introspection is generally unnecessary and redundant outside of committed relationships. Your brain has already background autopiloted and effectively done the work for you, indicating to you without hijacking you not to associate with that person.

Now beyond mere rhetoric, it is worth asking: is intuition solely a sequence of neurological processes, or is there an additional intangible component, like say, soul recognition? My intuition tells me it's both. I don't know exactly why or how, and yet, irrationally, there it is: felt certainty.
