I think people believe that I am the opposite of this, but that is because they don't actually know who I am. It appears that I am trusting of most people, but in reality very few people know the actual me -- like INTP, I don't count on people until I know they can be trusted either. And, as it has been said, it seems I have more real friends than I do.
Just looking again at this, makes me wonder... so you consider yourself wrongly judged by those who think of you as untrustworthy, and yet you admit that there are aspects of your behaviour that can mislead others into making that judgement... in light of this, do you think that perhaps your criteria for judging whether others can be trusted might need some revision?
I just say that because... "reject first" doesn't seem too great a strategy for making "real friends", so I'm wondering whether you're actually rejecting people who
can be trusted, on a regular basis...
edit - the same can be said of a lot of people actually, I can turn that on its head and say I often find INTP's difficult to trust simply because they won't trust me, not even a basic 'interim' trust if you know what I mean, benefit of the doubt kinda thing. I tend to conclude that since we so often misread each other and since objective evidence seems to favour the idea that most people are basically good, at least in intention, the best solution is to just give everyone the benefit of the doubt and trust them, then as you get to know them, make the odd mental note of their weak areas, those areas they're less
competent or perhaps less disciplined in, so you're not distrusting their motives but just doubting their competence at carrying out their good intentions lol It doesn't have to stop there, though, cos you can always help them to increase their competence...
