Re: DOES intuition
You mean practical by our social norms and what we've been socialized to do. Such as, an American not being paranoid about opening the door for a police man. I'm not paranoid, but I know not to trust anyone. My intuition may say not to open the door, or it may not. It's an instinct to be wary of others, while that instinct may be exacerbated by your conditioning (such as teaching a girl not to trust any man, or the opposite, teaching your children to trust every person in uniform).
I don't see how practicality comes into play in any of this. The only thing I see here is "common sense," which is instilled in us by the practices of our people.
