It also depends on how aware people are of their own reactions and how much experience they have of relationships so they can compare. I have a hard time dating non-duals nowadays because I painfully feel the incompatibility between us, it is uncomfortable and something is lacking. I mean just as a feeling, regardless of what socionics says. I can easily stop thinking about this socionics stuff when dating someone, but I cannot turn off my own awareness, at least not as easily. After all, socioincs predicts my own subjective reactions quite well. In that sense it is not socionics vs. just-follow-your-heart. Because they are often the same.
This is of course possible. And I know lots of ILEs whom I am not particularly fond of. Duality is just one factor, but an important one. It's not like I am going after each dual I meet. But socionics gives me a good hint of whom I should try to get to know better. And it gives me great hope.What if you end up with a dual with whom you have such different views on religion or politics that you just sit and argue all the time, albeit argue very well and effectively due to compatible communication styles?
Here again, it's not a matter of my feelings vs. socionics. They often go hand in hand. I meet an ILE, I type her ILE and I discover that I like being with her. Very often things go this way. If for some reason I dont' like being with her, then of course I wont date her. I would never date someone just because I think she is my dual, but often when I like to date someone she IS my dual. Socionics just confirms my own feelings again and again.And what if you've mistyped yourself, or the other person you're dating or not dating based on Socionics? It all seems very risky to me.
