I know this is "unscientific" and not supportable with actual facts, but---
---haven't we all met someone to whom we took an almost instant dislike? If asked why, we probably couldn't say much more than "I dunno---just SOMETHING---bad vibes!"
I generally let people prove whether they are assholes rather than conclusion-jump. I will admit that some assholes prove what they are within 1 or 2 seconds, which comes close to instantly. Thankfully, I have never had more than one or two assholes among the people I deal with more or less daily, and often, none.
