1. Haven't sourced enough information to understand MBTI to the degree necessary to make this call.
2. Enneagram appears to be a Fe-based construct which I reject beyond the instinctual stackings. As far as these are concerned if sx is defined as intimacy, then from as far back as I can remember, it's been the same. I have a strong need to connect but sp will put the brakes on if it senses any issues.
Since other members have expressed concern over point #2, I should clarify. This response is solely focused on E8.
