These ratings are the most significant for (very) close friendships, long-term romantic relationships, and the like. Less favourable matches may be interesting and acceptable enough in rather impersonal, professional/business situations. At last, factors outside of Socionics (such as shared values and interests) can make two people more or less compatible despite their intertype relation.
For a long-term romantic relationship, at least ★★★ stars are recommended.
Here are examples of different intertype relation couples.
With matching subtypes:
“Matching subtypes” implies the following combos: Ni-Se, Ni-Ni, Se-Se, Ne-Si, Ne-Ne, Si-Si, Fi-Te, Fi-Fi, Te-Te, Fe-Ti, Fe-Fe, Ti-Ti.
“Mis-matching subtypes” are any combinations that are not mentioned above.
With mis-matching subtypes:
Use this calculator for the most accurate result. If you are a strong subtype, pick 2 (not 3 because that one is unrealistic). If you are a moderate/average subtype, pick 1. If you have no subtype, pick 0. “Good” at 66% is the equivalent to 3 stars. “Excellent” is 4 stars and above. Matches below 66% are not recommended.
Note: Even though Duality is rated so highly, it does not mean you cannot have a good and satisfying relationship with another match – or that Duality will always work for you. Read more on this issue here.
