These were some of the most interesting function descriptions that I have read. To a large extent, I identify with Ti, Fi, Ni and Ne in this theory. It therefore makes me wonder
if the socionics definition of Ti is wrong, and it makes me wonder if the functions can appear in any order - as the inventory states.

OTOH, it seems that some functions are missing that socionics has down pat - socionics Se and Fe, for instance.

In any event, it is interesting food for thought: could the functions occur in any order? Do you identify with different functions in the above descriptions?

I find that theory's definition of Ti to be spot on in my case... But clearly the theory is not absolutely perfect either, as that is not what I am trying to say...
