This is interesting, because my (more literary than scientific) understanding of ego development includes becoming aware of an 'inner tribe' or 'multiple voices' inside one's mind which simultaneously are and aren't the self, to differing degrees. Integrating these voices, allowing them to discuss with each other, et cetera has been a method which allows great insight into problems where reaching a solution was blocked by a limited perspective.
Accessing these voices is invaluable for writing fiction, perhaps the difference with a tulpa is the level of reality and influence ascribed to a single 'not-me' voice?
I also see the ability to have an internal Socratic dialogue as requiring a kind of ego-splitting, in a way that could be conceptualized as a tulpa asking (often surprising) questions.
Very abstract and hard to talk about stuff, I hope that makes sense.
