I think this is very well said.
to an extent. . .
Dont you think it makes it easier for duals to find each other if they know what they're looking for? I.e. how many of one's duals does one pass by before finally getting to know a dual well enough to click? And many people don't end up finding their dual, some people even end up marrying their conflictor! And then have to divorce, or live unhappily.
I think it's a rosy view to say that duals find each other naturally and marry. That's looking at just the dual couples which are not all the couples out there. And it would help to deal with all the bad relationships (not avoiding the relationships per se, since you need to get to know the person before applying socionics) before the dual couple does meet and the wondering, why didn't it work out? what's so bad about me? when it's really just a personality clash.
Furthermore, for some types of dual pairs, the dualization process can be very complicated as each person is filled with doubt and fear of rejection (SLE-IEI for example), so if each one knew socionics that could perhaps shorten their dualization and have a higher chance of success. But good point, i am not completely sure that knowledge of socionics would change each one's perception of each other and the consequent feelings.
I know for me knowing socionics didn't change anything other than understanding our interactions. All i know is it's possible my dual enjoyed my company or at least wasn't bothered by me, but i have no idea where along the dualization process he was, nor whether there was any physical attraction whatsoever, nor whether he had any opportunity to experience ease from my ego functions. I recognized his strengths and felt what socionics describes before i even discovered socionics.
