I believe introspection would be the domain of the introverted functions. After all, they deal with a person's "inner world" so to speak. But is one more "introspective" than the others? Or do we use all of the introverted functions in introspection, with the ones in our main type leading the way? If the latter is the case, how would people with different introverted functions in their type experience introspection? Going further, would people with an introverted function as their dominant function have a tendency to be more introspective?
