Why 76%?

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): S and N → +2 · T/F (how you handle drama): T and F → +4 · J/P (who plans): J and P → +10. 46 + 14 + 2 + 4 + 10 = 76.

For comparison, the same two types score 71% 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.
