I have this knack that I've had from a young age: whenever I meet someone I can feel them out and know whether or not they are truly genuinely nice people or if they are fake within 45 seconds of meeting them. I wouldn't call this being judgmental because it's not based off of anything other than the "feel" that I get when we come into contact. I feel like if it was just based off of their appearance it would be judgmental, but it's based off of a "feel" I get from them. So I guess my question here is what allows me to just "know" this about them? Is there a name for it? What is it that predisposes me to being able to feel out whether or not this person is essentially good or bad?
