Easy friends
One is the one who quietly fixes it, the other the one who quietly fixes it — a duo that just works.

Why 92%?
Every pair starts at 46. Then each letter adds points: E/I (how you hang out): both I → +14 · S/N (what you talk about): both S → +18 · T/F (how you handle drama): both T → +8 · J/P (who plans): both P → +6. 46 + 14 + 18 + 8 + 6 = 92.
For comparison, the same two types score 93% in our love-match rule, which rewards opposite E/I and T/F instead.
Both rules are our own design, not an official MBTI product, and personality types are not a science of friendship.
