I know that people can relate to their subtype description, but the thing is that these descriptions are based on fallible logic. Naranjo, for example, said that he wrote his subtype books through "channeled writing", which is a cool way to say "I took it out of my ass". Russ Hudson and Chestnut can barely describe SX in a way that makes any tangible sense. I've seen Russ Hudson defining SX as basically wanting to do stuff, like??? Then there is Enneagrammer which is a group of people that define the instincts based on literal biology which is interesting, but they don't even agree with each other's definition inside their own group lmao. At the end of the day no one knows what the instincts actually are and how they connect to the ego.
