INFJs prefer Introverted Intuition, while INFPs prefer Extraverted Intuition. This explains a conversation I keep having with my INFP husband, I think.
Me: We have X problem. I think we should deal with it by doing Y.
Him: I don't know about that.
Me: Okay, you come up with something you like better if you don't want to do Y. I already came up with a solution.
I, preferring Introverted Intuition, have a "one and done" approach. I have the BEST solution, and don't want to consider others. He would probably prefer to come up with different options (and I, probably, would have to settle on one).
When he gets home, I'm going to test what he thinks of this theory.
What do you all think?
