Near the middle on one letter? Read the neighbours
Each of these types differs from INTP by one letter. If that letter came out near the middle for you, the neighbour may describe you too.
ENTP · Idea Sparker
Energy (E/I): outgoing (E) instead of reserved (I). The other three letters are the same.
ISTP · Hands-On Fixer
How you see things (N/S): down-to-earth (S) instead of imaginative (N). The other three letters are the same.
INFP · Inner Dreamer
How you decide (F/T): heart-led (F) instead of head-led (T). The other three letters are the same.
INTJ · Long-Game Thinker
Plans (J/P): structured (J) instead of spontaneous (P). The other three letters are the same.
Who INTP clicks with
By our pair rule, these four types click most easily with INTP. It is a rule of thumb from four letters, not a verdict.
ENTJ · Driven Organizer
Both imaginative (N) and head-led (T): you tend to see things and weigh them the same way. Reserved (I) and outgoing (E), spontaneous (P) and structured (J): opposite on energy and plans, so each can cover what the other finds harder.
ENTP · Idea Sparker
Both imaginative (N) and head-led (T): you tend to see things and weigh them the same way. Reserved (I) and outgoing (E) balance lively and calm, and as you are both spontaneous (P), your daily rhythms line up easily.
INTJ · Long-Game Thinker
Both imaginative (N) and head-led (T): you tend to see things and weigh them the same way. Both reserved (I), so you like to spend time the same way, and spontaneous (P) meeting structured (J) balances making plans and changing them.
ENFJ · Warm Motivator
Both imaginative (N), so talk flows easily, and head-led (T) meeting heart-led (F) keeps you both thinking. Reserved (I) and outgoing (E), spontaneous (P) and structured (J): opposite on energy and plans, so each can cover what the other finds harder.
How we rank: 2 points if you share N or S (how you see things), 1 if you share F or T (how you decide), 1 if your E and I differ (your energy balances out) and 1 if your J and P differ (one plans, one adapts). 4 or 5 points: clicks easily. 2 or 3: fits in parts. 0 or 1: takes some effort. Equal points are ordered by the same conditions: N/S first, then F/T, E/I and J/P. This is a rule of thumb from four letters. People of one type still differ a lot in their real scores, and no pair is set up to work or to fail. Comparing your real results is more precise.
What four letters leave out
Four letters leave out one big part of personality: how you handle stress. Our test shows it as a fifth bar, steadiness, and uses it when you compare with someone.
