I've done this twice now. And it works.
You act as if you are the person's dual. You see what they value and devalue. You see how they value or devalue your functions. Then you use the ones they like.
The first guy I experimented with using this method was a blatent Reinin Declarer. I think he had Si as a first function, and he disliked Se. So because I am naturally a Declarer, I began to act as an Asker. I took the emotion out of any of my words, and used a dry tone with him, asking him to describe things which he was happy to talk about.
The second person I experimented with is, I think, an SEE. I don't know for certain. But she was also a blatent Declarer. We clash. This is because I'm forceful, and she's forceful. So I yield. I become quiet, and only interject in conversation when I'm asked for my opinion about something, or when I can perfectly execute a statement. But, after these first few minutes in conversation which felt forced and unnatural, I began to act naturally with her. The conversation flowed well.
So try it out sometime. If you're naturally forceful, take a back seat, and learn a few things. If not, attempt to seek out what your interlocutor actually wants.
