INTP vs ISFJ

INTP (Lattice) and ISFJ (Keep) share some furniture and not others. Read both encyclopedia pages rather than forcing a winner. You open one question to clarify it, and somehow it eats the evening and the original question. There's a spare charger in the glove box because you've already lived the day someone needed one.

Lattice is Typewell's name for INTP. The letters are Introverted, Intuitive, Thinking, and Perceiving. Introverted: the real lab is inside. People are optional equipment, sometimes beloved, always a little expensive in attention. Intuitive: you hop to the abstract, the analogy, the system under the system. Thinking: you trust a model that holds, even if it makes the room less cozy. Perceiving: you keep branches open. Closing feels like lying if a better distinction might still arrive. The inner architecture can be beautiful. The outer one — dishes, dates, a sent note — is a group project you forgot to staff. This is a preference sketch, not a certificate of genius and not a pass to ghost your own life. It isn't the official MBTI® and it isn't a diagnosis.

Keep is Typewell's name for ISFJ. The letters are Introverted, Sensing, Feeling, and Judging. Introverted: you refill in a quiet room, even if you spent the day attending to faces. Sensing: you remember how the person takes their tea, how the last crisis actually went, where the spare lives. Feeling: the decision has to sit well with the people you're responsible for. Judging: you close the loop — the form sent, the charger packed, the birthday not missed. Together that's a keeper of the small load-bearing facts. Families run on this. So do teams. So do you, until the tank is empty. This page isn't a hymn to self-erasure. It isn't the official MBTI® and it isn't a diagnosis.
