I'm basing it on my own experience and understanding of reality, no "personality typology systems" involved or needed. Not everything is graphable. People talk about getting social energy from interacting with others vs. getting it from being alone, I feel I get social energy from food and sleep, just like the rest of my energy. I enjoy being alone, I enjoy being with people, sometimes I want to do one over the other, but neither predictably more than the other. I get tired from being awake and active for long periods of time, how many people are or aren't around me doesn't change that. Like I don't even think it's a spectrum between the two, that's still forcing an arbitrary dichotomy that I just don't think truly exists. Ultimately it comes down to prescriptivism vs descriptivism, and the latter is always going to be more "true" than the former. It's great if other people find the comparison helpful for understanding themselves and true to their own experiences, I simply don't. And if I don't, I know there are plenty of others that don't, because I'm exceedingly average and no one is that unique.
