An obvious alternative hypothesis to what you describe here is that new behaviors start out being systematic and with enough practice become intuitive. I can't recall where I heard it from, but there's a theory that there's 4 stages of knowing

That's one of Abraham Maslow's ideas. Of all the educational philosophers they paraded in front of us while I was doing my Di. Ed. I have to say Maslow was the most interesting (to me). I certainly preferred him to de Bono and his thinking hats and it is less 'arbitrary' than Gardener and his 'multiple intelligences' that my professors loved so much.

I don't think 'the stages of knowing' have been the subject of any explicit scientific investigation but the concepts do seem to have direct relevance to the research on developing expertise that Ericsson is noted for collecting and compiling (first in his own book and then in the handbook.) There is solid research on the impact of training intervention that can described as moving from 'unconscious' to 'conscious and there are entirely different training needs for developing 'conscious competence' than for moving 'conscious skills' to 'unconscious'. We can even have studies (on basketball free throw shooting) that can predict how different motivations work best in for each stage.

I've followed you down that tangent a bit (It's a subject I'm fascinated by!) but how does this relate to what I was saying about possible Think/Feel differences? It is somewhat isomorphic. Anyone (without a significant dissability) can gain skill then expertise in, well, more or less anything. But there are preferences and tendencies in response that people will naturally take unless they are motivated to train themselves (or are coercively trained) to do it differently. An example:

If my sister sees a kid that has been punched in the nose by a bully she will naturally inclined to comfort the victim. I will be naturally inclined to go and beat the bully to a pulp. Now, my sister can go learn martial arts and train herself to implement a policy of vigilante justice if she wants to. Likewise, I can learn what is most effective in comforting victims and hold my rightious anger in check somewhat. But there is a clear difference of personality here. One that is influenced by, but not directly determined by, testosterone in the brain both right now and during developmental stages. This is a different difference to T vs F but it is one that is more obvious and one that I can actually describe reasonably. I just haven't looked into MBTI all that much in the last 10 years or so.
