You could argue that outside-in versus inside-out is more of a temperament than it is a form of neurodivergence. For example, what you're describing is basically typical of how Keirsey describes concrete versus abstract reasoning in Please Understand Me. And it could be kind of alienating to be the one abstract reasoner in a group of concrete reasoners and if you believe his statistics it's kind of likely that you'll find yourself in that situation a lot because you gravitate toward the abstract rather than the concrete/operational aspects of a concept.

I generally do the same thing when I'm learning something, and I have to fully understand a concept and then attack the concrete applications of the concept. But I've also learned how to go the other way when I need to because much of the technical writing I encounter is written for people who need a lot of examples but don't follow abstract concepts. So I've internalized building up the abstract concept from the concrete examples.
