Your strengths sit exactly where their blind spots are, and theirs where yours are. The famous Socionics 'perfect fit'.
What it feels like
Effortless. Each of you handles, without thinking, exactly the things the other finds draining. Conversation is easy, silences are comfortable, and help arrives before it's asked for.
Where it works
Long-term partnerships, marriages, close friendships, co-founding — anywhere two people need to cover each other completely.
Where it strains
Almost nowhere once established, but duals can walk straight past each other early on: the fit is so unlike the friction most people mistake for chemistry that it's underestimated at first.
