3. Factor: about the Big Five and similar clasifications

So... Now that we have already discussed the consciously chosen or willingly created factors that can determine the success of any connection with another person, we can now move on to not-so-conscious and perhaps not-so-significant factors. They mostly try to describe specific character traits and features. These classifications can be based on immutable things, for example, zodiacs are based on the date of birth, well, or some things that can be changed, because the MTBI classification or even the results of the Big Five test can change during a person's life, as he works on some of his character traits.
The MBTI type indicator is created according to K.G. Jung's "Psychological types" classification. This classification doesn't have a very solid scientific basis, so I don't really know if it's worth studying this system thoroughly,  but nevertheless, the tests are interesting, the descriptions of each type are too; there are pages, groups, and even dating apps that either rely solely on the MBTI or make it a significant part of them. From my experience, I can only say that without trying to change my behavior and understanding, my MBTI always had one result - INTJ... But after starting the self-knowledge work, my MBTI type started to change, and now I have no idea, if can I rely on any type in this classification... maybe the hardest part was to "break" the trait of introversion, but quite often I also get the letter of an extrovert now, so somehow I don't pay much attention anymore.
Actually, according to K.G. Jung himself, personality typology has 2 elements:
- namely extroversion and introversion and
- sensations, thinking, feeling, and intuition
It is from this classification that the Myers-Briggs personality test and the 16 personality types were created. According to the Swiss psychologist himself, it is best to simply improve your less expressed tendencies, for example, it is best for an introvert to improve his more extroverted side, or, say for an intuitive person - body sensations, etc.

The Big Five - a topic I'm less familiar with, but maybe even because of that it's more interesting... In addition, at least at the moment, many in psychology recognize this classification as sufficient to determine the personality type, although it already shifts towards 6 personality traits instead of 5 - "[...]it has been suggested that the Big Five system should be replaced by HEXACO, or revised to better align with lexical evidence.." (from Wikipedia). What personality traits are included in the Big Five:
O openness to experience
C conscientiousness
E extroversion
A agreeableness
N neuroticism
To get along well with a person in a relationship, it is best not to have a very big gap from each other in all 5 characteristics, except for neuroticism, the less neuroticism both have, the more stable the relationship is. And, well, this indicates the need to try to work on it, if there is a lot of neuroticism, and, yes, it is possible to change it- each trait. For more info on OCEAN traits, see the video bellow

This group of factors influencing relationships can also include love/apology languages.

And here is a quick video on the Big Five, a bit short, and a bit poorly described in places but with awesome illustrations, and it adds plenty of clarity and play. I hope you will find it interesting along with everything else here, in this entry.

And visuals for example:  Conscientiousness - personality trait and its opposite poles and why it's best to keep them balanced.

And in the finale, perhaps it should be said that any, even the most unpopular and irrational classification and contemplation on it is useful simply because during the process you keep thinking about the compatibility, qualities, and character of the two of you and in this way, you get to know yourself and the other person better; it is enriching in any case... And I mention once again that the characteristics of the Big Five can be polished and new behavioral habits can be trained even with a higher neuroticism trait, which is probably the most difficult. It is even advisable to develop balance in all 5 traits. Good luck :)
