Everyone knows "complicated" is code for "bitch." -Gone Girl (2014)

Methods

I was trying to classify and model all my good relationship, so I began to look into my friends, their interest, outlook, and personality.

The first model I bumped into was Myers-Briggs Type Indicator, MBTI. It's a really popular model. I soon discovered it has problem that the model itself is not reasonable as it labelled a lot of personality as incompatible, which is not, like thinking and feeling. IQ and EQ are definitely not contradictory to each other, and mostly often, positively correlated.

So I did some research and looked into the wikipedia page which lists a lot of psychology models.

I did not came up with any satisfactory model that is mature enough.

IMHO a good model, would be listing personality traits as features as independent as possible. For sure there will still be correlations, and it would be a tough work to solve for the coefficients, while distinguishing between those important features and others.

In the end I decide I should take a different approach. I found the MMPI-2 questionnaire and went on with a more empirical method, by simply trying to understand my target according their existing reaction under certain situation, without the abstraction of personality traits.
