9 and Sensing
The general consensus is that all subtypes of 9 are necessarily Sensing types in Socionics. For SP9 it's very obvious why. SO9 and SX9, on the other hand, do have a disconnection from their own preferences and feelings that can be related to Si, but it's not that straightforward, and especially SX9's bad relationship with its body is strange.
I've read some people saying that Naranjo's original description of 9 does not include any reference to Sensing that can rule out Intuitive types, but I also don't know to what extent that is true.
What do you think about the relationship between 9 and Sensing/Intuition, and most importantly, what are your arguments and how strongly do you think the original relationship between 9 and Sensing is Naranjo?
