I have a similar experience to stingpie. When I meet someone new, they’re a completely unique person to me. It just doesn’t cross my mind to take experiences with other people and apply them to this new person. If you ask me to consciously think about it and put a hypothetical someone in a bucket, then I can tell you that given two people with traits x and y, which one is more likely to fall into a particular bucket. But if I meet this hypothetical person, I’m not going to act as if you belong in that bucket. That’s not something that comes naturally. I’m guessing this is also what stingpie is trying to express.
