In dual relations, the leading function of one partner is the suggestive function of the other, and the creative function of one partner is the mobilizing function of the other. Thus, the ego functions (the strongest and most socialized) of each correspond to the super-id functions of the other (the area where the person needs and expects assistance). Likewise, the super-ego block of one corresponds to the id of the other. In this relation, just 1 of 4 Jungian dichotomies is shared—rationality/irrationality. Duality interaction is generally rewarding and satisfying for both parties, providing inspiration and support. Duality is a central theme of the philosophy of socionics study: Augusta often stated her position that a person who is estranged from contact with a dual partner must cope by unnaturally distorting their personality, a phenomenon called "type masking". Relationships with conflictor types are cited as particularly troublesome: it is not uncommon for a person in a close relationship with their conflictor to develop an acute neurotic condition.
