Well, I suppose what I mean to say is that it's not inclusive within the gut - these needs can be expressed & fulfilled in other ways, specifically mental & emotional ways. I also think that just because someone is neglecting a need for whatever reason, and seems to act neurotically or out-of-step with something, does not mean that isn't their primary need in life. People can very easily neglect their primary needs, something I think the low styles of each enneagram type help to illustrate very well.It is about instinct. In enneagram there's the mental fixation at the Head Center, the passion of the heart at the Heart Center, and the instincts at the Gut Center. If you say it's not instinctive, you completely miss the point.
This also relates to my idea that the instincts aren't stacked - you have a primary motivation in life, and you're either fulfilling it, or you're not. Either way, it's on the radar, it's in your thoughts, it motivates your behaviour. You could be running away from it, making excuses for it, obsessing over it, chasing it, ignoring it, attacking it...whatever it is, it's like a magnet under the ground dragging you through life. And you're either tending to it or you're not.
I honestly think that to make things more complicated than that serves no real purpose to anyone.
