Socionics is not an adjunct to the MBTI, nor are its findings synonymous, even though both systems result in 16 separate personality type designations.
The following research on the MBTI will show you that this test is an unreliable measure of personality type:
MBTI measures personality with a written test consisting of yes or no questions, in which the test taker answers according to their agreement or disagreement with the declarative statement meant to indicate the personality. The problem with this test is that it relies upon numerous questions that are no way indicative of personality.
An example of one of these questions "You are usually the first to react to a sudden event:
the telephone ringing or unexpected question" (http://www.humanmetrics.com/cgi-win/JTypes2.asp) is used to relate with extraversion. A person may be in an especially "excited" and in an energetic mood in a given moment which would cause them to react faster; that is not a measure of extraverted typical attitude, as indicated by Carl Jung's Psychological Types; not everybody's behavior is the same at any given moment and Carl Jung was very specific in mentioning that in his work.
In addition, the MBTI separates personality types in a way that results in types which are inconsistent with the actual differentiation of human psychological patterns. Human psychological patterns are not divided along the lines of eight dichotomies of E/I, S/N, T/F, and J/P. Socionics measures the dichotomies together; they are measured in tandem, as they should be, for instance, Extraverted Thinking (Te).
Furthermore, Socionics has a Visual Identification component, which identifies types not by the test taker's choice of answers, or by the test taker's particular preference for personality orientation, but simply by the configuration of the test subject's physical features. One can only assume that a test taker is answering the questions in a manner consistent with their actual emotions and thoughts, and that those answers are not being adversely affected by unique circumstances influencing the test taker's mood at the time of the test. But, even with all the makeup and hair pieces money can buy, looks fundamentally do not lie. The basic structure of the face and the orientation of the spinal column to the skull, which are key factors in accurate Visual Identification, can not be altered short of expensive and painful surgery.
