No, you're wrong. they are the same type, yet MBTi says that introverted thinkers with extraverted intutuion (TiNe), have a fourth function of extraverted feeling, and that this is their weakest function. This fourth function is the equivalent of the suggestive function in socionics, and not equivalent to the the POLR in socionics. The MBTi people did not delve deep enough into the typology to discover things as the the POLR and role function; it is simple not part of the vocabulary. Nontheless, it does not mean that there is not the potential for the existance of those terms under such system.Originally Posted by MysticSonic
