You discount wings needing to be next to each other?
But what do wings actually mean? --just that you are on the border?
Isn't that analogous to an INxP not knowing what their dominant function is? But most MB enthusiasits don't dispute that the auxiliary function of a healthy type ought to be the opposite orientation, and opposite on the judging/perceiving type of function. Would you say an INxP is FiTi or TiFi?
Also, what about the core desires/fears, levels of health, and directions of (dis)integration?
How do those fit in?
