I learned the Big Five in a Personality psych undergrad class. It was disappointing because well not surprising because academia focuses on replicable data and the Big Five traits while accurate in their streams will give you that on an individual but I feel the context is lost. The vagueness of the MBTI confuses many but and Jung I felt was on course when he focused on the art and system that could be created to explain ...the MBTI like the Enneagram gives a grid for everyone to relate back onto each other. This enables compare and contrast and on the worse and best ends stereotypes to be garnered both those that translate to instant aha moments on self and other...e.g. I'm friends easily with Melissa McCarthy lookalikes acta likes who easily are I/ENFPs. The worser is when this is used in an unhealthy way that discriminates or generalizes too much. E.g. you give me your Big Five results and I can tell more or less if I'd want to be around you, can help you in some way or vice versa. You tell me your MBTI hopefully if it's accurate and match that with your physical appearance and mannerisms and everything makes a lot of sense without me elucidating. It's like a whole hologram of understanding downloaded instead of accurate but bytes of data I could use but can't create a story for or relate back to myself or those I've known. They say you meet the same person again and again until you learn the lesson.
