The five trait system of Extraversion, Conscientiousness, Openness, Agreeableness, and Neuroticism is considered more scientific than the Myers Briggs and other theories. But I think they are more similar than first appears. Extraversion is obvious, Openness is quite similar to Perceiving, Conscientiousness to Judging, and high scores in Agreeableness and Neuroticism both are similar to Feeling.
I think Biblical examples are more reliable.
For example;
Abraham ------Generous.
Isaac ----------Strict.
Jacob ----------Harmonious.
All depending on the soul, not all souls are alike.
Our story starts from day one,
If we think in terms of all souls being different and instead of placing each in a certain category,
We think of the book we are writing has diffent coloured pages,
so a kind soul may have blue pages in their book
and a strict soul may have red for example.
At the judgement these things will be taken into consideration.
Which would be fair and just,
If a kind soul is generous and charitable, what is so remarkable
about that?
If a strict soul makes an effort and does a kind deed, would that not be a greater merit?
It is so I try to think anyhow.
