They're meant to be caricatures that people associate with particular traits. You're pretty much supposed to pick the one you like being associated with, whether it's accurate or not.
People here don't like the idea of sensors, because here we seem to have associated that mindset with fundamentalist religious beliefs, intolerance towards new ideas, parents that tried to impose traditional roles on their children against their will, a lack of curiosity, shallowness and superficiality, and an inability to grasp irony or sarcasm. They'll make exceptions for an individual sensor once they "prove" themselves, but in general this is what people see.
Now, are sensors really like that? Probably not, but it doesn't matter, because that's how people want to see them. And in an archetype system that's based on caricatures anyway... there's nothing to balance it out. Quite honestly, the whole idea of "sensors" and "intuitives" may only seem to exist because of confirmation bias. The whole thing could be in our heads.
The main thing you need to know about this system isn't its intended use, it's the way people have ended up using it. It's mostly something that some people find helpful in uncovering the parts of themselves that they've repressed, and gives them images to project onto other people in order to help them rationalize out how they got where they are, and what kind of things they need to do to move forward. It allows people to rid themselves of guilt and other kinds of baggage by enabling them to blame their environment instead of themselves, so that they can change. Some people are programmed to blame themselves for everything, and really need something like this.
Honestly, I think you'd have a much easier time here if you just changed your S to an N. You're intelligent enough that few would question it.
I mean, think about it... you say you're the only one who has done things differently in your family. You could go a little further and say that's because you're creative and they're not. You could decide that you were a social reject because no one appreciated your creativity/uniqueness and differences from other people, looking down on you for not conforming to their way of doing things. You can see why that kind of perspective would be appealing, right?
Do you see what I'm getting at here?
