A. Shmelev in his review of the book "MBTI: type definition" by I. Myers-Briggs and P. Myers notes the highest popularity of socionic books in Russian and remarks that their authors are appealing to the literary and artistic associations of the mass reader, in contradistinction to books on MBTI, which contain the empirical and statistical data on the types distribution in professional groups. S.A. Bogomaz considers the socionic typology as a version of post-Jung typology and believes that on a number of criteria it is more perspective than MBTI for the study of the differences between people, because it expands the volume of the typological features and offers an opportunity to form various typological groups with different motivations, attitudes, temperament, perception of information and thinking styles. It is also important the existence of preconditions to study intertype relations, that are substantially not developed within MBTI. S.A. Bogomaz thinks that the creation of the theory of intertype relationships is undoubtedly contribution of A.Augustinavichiute to the development of Jung typologies.
