This was just my take on personalities and personas, from what I’ve learned from Myers-Briggs and Cognitive Functions. Not claiming to have figured anything out or even know what I’m talking about. These are just my thoughts and interpretations of what I understand. Maybe even just relabeling terms in a way that makes more sense to me.
There is a very computer-like analogy of how we process information – input, process and output. Or simply, we built computers analogous to our process. Our relationship to the ourselves and outer world, how we receive and process information, and how we interact with the outer world. Every computer is constrained to the same logic and parameters, not on a spectrum but we as humans, have a dichotomy and each dichotomy on a spectrum, which is why each one of us have such different personalities but also many similarities. This makes the most sense to me, we are all different but the same. And I think the dichotomies are somehow inherent to the relationship between our right and left brain and the dominant personas on each side.
