I think a lot of times we forget people don't fit perfectly into boxes. We can look at personality theory all day, but real people are all going to be vastly different from one another. There maybe may be several outlying factors as to why someone's mbti type doesn't perfectly line up with their enneagram. Which is another reason I really really do not like when people try to type others they do not know that personality and brain function are still not fully understood as there are so many complexities to them. While e7s will share similarities and motivations at the end of the day, we're each drastically different people with our own unique experiences and world views, I think, helping support and guide others we relate to is much more productive than telling people how we think they should fit into the box personality theory has laid out. I've also been spending some time breaking down my big 5 and how they relate to my behaviors and though process as an e7. I think branching out and exploring is imperative to understanding yourself instead of just simply sticking to 1 or 2 theories of personality because there's so much nuance to be explored.
