Mars Briggs is based on this of union, you know, personality types as well. There's a richness and depth in there that I think can get overlooked. Some tools will expose different differences to people than others. And the EN and Mars Bricks things give you some a framework. But if you just limit yourself to one, when that one doesn't really help and serve you as well,. it might for some, it might for others. For some people,  if you try to kind of like, exhaustively cover humanity and everyone's differences with those, you're obviously going to be caught out.
