Yes I also think creation and destruction are intertwined and feed upon each-other. Just like many other pairs of apparent opposites.

I think it's not hard to come up with, describe and create questions that address specific stereotypes. IMO, the types reflect common patterns of several major human motivations and also what kinds of problems the associated drives and actions can lead to. How it can get out of balance. The individual types themselves of course are way simplistic. I have done lots of personality tests in my life, including more esoteric ones like this and more scientific ones, and never felt they were really mysterious. In my view, it's all based on creating stereotypes on whatever factors, then expanding and mixing them. Often there is a larger "system" it's all placed into as well as a context (i.e. motivations, cognitive styles, what sorts of interests and abilities people with certain natural motivations/traits tend to develop etc). I don't take these tests/ideologies very seriously but tend to enjoy them because I am fascinating by systems and the ideas behind them even if esoteric.
