 : I am in agreement with what you are saying, the problem (for me at least, having a somewhat broader and yet more distant view than most) is that hand in hand with ""Doing it Right"" is the clear assumption that everything else is ""Doing it Wrong.""  It is quite impossible to separate the ""how"" and the ""why"" since the ""why"" is based on an assumption that DIR is the ""revealed"" word, rather than just one splinter of the tree that works well in certain circumstances.  Philosophically, DIR is so defined by arguments as to what it is not rather than by what it is that, funny as it sounds, a good case can be made for much of DIR, when applied to open water, for example, is a classic ""equipment solution to a skill problem.""  It is not clear to me how this can be handled in an encyclopedia situation except by saying that DIR exists, is controversial for a number of reasons, and here are some links to websites that describe it.
