Vor-Syn Cog, or why socionics might be inconsistent
Vortical-Synergetic Cognition is associated with thinking in terms of evolution in time. :Ni: is the function used with evolution in time according to the internal logic of Socionics. So there must be a cause-and-effect relationship between :Ni: and Vortical-Synergetic Cognition.
My first hypothesis was that :Ni: is in the ego block of all VSC types and not in the ego block of all nonVSC types. Counterexample: SLI is VSC but doesn't have :Ni: in the ego block.
My second hypothesis was that :Ni: is a valued function of all VSC types and a non-valued function of all nonVSC types. Counterexample: ESE is VSC but doesn't value :Ni:. It has :Ni: as most vulnerable function.
So I don't think Socionics is internally consistent.
