1) Share why you think have the alignment that you do, and how relevant of a descriptor you think it is.
I generally test Lawful Good. I have a definite internal code that I live by, and am somewhat old fashioned about my notions of honor. I believe that we have a responsibility to go beyond not doing harm, to actively doing good, even when it's not the easy or convenient thing.
Admittedly, my commitment to my personal code exceeds any interest I have in rules or authority figures. I'm usually oblivious to those, and occasionally disregard the ones I feel are stupid. I don't usually actively challenge the rules, but would rather just bend the system if I feel I'm being prevented from doing something that really ought to be done. Generally speaking, I recognize the necessity for rules without swallowing the kool-aid that all what's lawful is good.
I suppose the downside of Lawful Goodness is a certain narrow-mindedness. I'm admittedly not terribly sophisticated when it comes to moral questions--my thinking tending towards the monochromatic--and am somewhat resistant to excessive philosophizing or thought-exercises. Relying on my code and my intuition is what feels the most natural to me, so it's what I go with.
Do you think it is more, less, or equally as relevant as the MBTI/Jungian typology or the Enneagram?
I think it provides a macro-perspective that the other two systems do not, giving a sense of how the individual functions in society. I guess MBTI kind of gets at that as well, but the picture it presents at that level is still of a collection of individuals with a relatively lesser sense of how they all relate to each other.
Would you take this system into consideration when it comes to whom you date?
Not explicitly. Having said that, I think that as someone who is Lawful Good I recognize I can be intolerant of someone whose shit is lacking in the values department. I couldn't be serious about someone who wasn't "Good" simply because I wouldn't be able to respect them. There are certain things you simply can't compromise on.
