INTP Type Dynamics and Cognitive Functions (Or Not)

I won't be covering type dynamics or cognitive functions here.  Type junkies may be wondering why not, since Ti, Ne, Si, and Fe are widely considered to be characteristic of INTPs.  But there is doubt over whether the cognitive functions exist.  You can read about it here

Although many of the observations that have been explained by cognitive function theory are valid, many simply are not.  I believe that cognitive function theory causes more confusion than it clears up--particularly in the all-important area of figuring out one's type.  I just don't see much point in pouring more time and effort into a bucket so full of holes, and have opted to leave out this part of type theory.
