Frequently asked questions
- Which type is the best match for ISTJ?
- In this friendship model, ESFP scores highest at 90 points. The score explains shared and complementary preference patterns; it does not mean they will actually be better friends.
- How is the ISTJ compatibility score calculated?
- ISTJ is compared with the other 15 types using one consistent friendship model. The same criteria apply to every type, so the scores can be read side by side.
- How large is the gap between first and last?
- For ISTJ, the gap between ESFP (90 points) and INTJ (81 points) is 9 points. The gap reflects how much the preferences overlap, not how difficult the relationship would be.
- Does a low score mean we cannot get along?
- No. The score describes overlap and complement between preferences. In real relationships, communication, shared time, and context matter far more. Read a low score as a heads-up about where you differ.
