Myers-Briggs Personality Types in the Bible

I’ve taken the Myers-Briggs several times for various classes (having a Communications minor in college leads to that), and I have scored ENFJ repeatedly.
The only difficulty is that I score equally between Extrovert and Introvert, which they say means you can make a choice of which you prefer, and which Extrovert seems to fit far better.

The thing that I find interesting is that your list there gives a different biblical character for ENFJ and places the one biblical character that I have seen associated with ENFJ in a different category.

The chart on ENFJ there classifies David as one (as well as a number of other famous people and even fictional characters).
