If functions are direct brain processes, how can some ethical types be good at math? Wold that mean that they're even better at things equivalent to Socionics ethic in BrainTypes than other ethical types? All i can see is a dissimilitude between BrainTypes and Socionics. If what BrainTypes measure is accurate, i can see how functions would be the abstract vehicles to the actual brain processes. Functions would be how our personnality uses the brain and not the result of direct potential. Anyways, whether functions are like i speculated or not, they don't seem to be the same thing as JN measures, resulting in Socionics type not being the same thing as BrainTypes type.
