Yes.

I would add that another insight is that it's much easier to communicate with people when you learn their language. It might be much easier for a nerd to introspect about their personality when prodded using MTG, a familiar framework. Similarly some people expect their relative positions in n-dimensional personality space to be codified using zodiac signs. If you can do so, meet people on familiar ground, at least at first.
