Big 5 is accurate but hard to explain. MBTI is fairly easy to explain and honestly it's not like astrology where it is random, an INTP does act very differently than an ENFJ
If you’re not a Taurus, the elements of a Taurus are not supposed to relate to you. that part of the framework is theoretically irrelevant.
If you think you’re an INTP you likely are. If you think you’re a Taurus then… doesn’t matter.
If someone is barely extroverted you’re assigning them a full E anyways. That’s a poor predictor.
