@Balckberry by test, do you mean socionics test or whatnot? because I did a ton of those and I get varying results that are more funny than helpful at this point. I like doubting things anyway.

I guess, without the luck of random same quadra intereactions, a person might be able to find a place within themselves where they reject what was taught to them to make place for their own truth, but this isn't a ten step trip that can be done over the weekend. Even people who grew up in same quadra environment can be messed up inside. As it is said, duality doesn't grant a good relationship, many more factors play. Most people aren't free of inner conflict.
One has to want to find this place and strive for it at the same time as being patient and open minded.
