      To the extent a system of thought exhibits qualities such as internal
      consistency, rigour and emphasis on 'consequences' then hard-to-varyness
      will emerge as a straight consequence of the fact existing principles
      will act as constraints on subsequent principles.

      It isn't a property of individual explanations. It isn't a quality of
      individual explanations. It is a quality of the relationships between
      principles.

      Nor is it an indication of how difficult or close to reality the
      explanations are getting. This is because a system of thought creates
      its own reality, the constraints on subsequent explanations are decided
      entirely by the legacy of former explanations.

      The substance of hard to varyness most closely reflects how easily new
      principles are added to the system. In the case of the PopperDeutsch
      system, new principles are added immensely easily and that is because
      there all forms of criticism involving external systems, such as
      scientific evidence, common intuition, real world events, history, and
      so on, the system has a veto over.

      So the major constraint on new explanations is that it must be
      consistent with what is already there. The major potential for criticism
      of new explantions come entirely from within the fold of popperianism,
      which means not of the kind that will be challenging the 'constraints'
      on that new explanation, but only the extent it conforms to those
      constraints.

      Principles like the jump to universalism are by definition actually
      described as "easy to happen", and for this reason new instances of
      jumps to universality in the system act as incredible constraints which
      generate immense forces of 'hard to varyness' but now the meaning of
      that because negative.

      It's worth noting that 'hard to varyness' in Science might be associated
      with brilliant difficult to find theories, but the reason is because the
      explanations have to cover so many bases and be consistent with so many
      things, all of which can be thrown out by a whole variety of kinds of
      criticism. They are not protected the way popperianDeutschian ideas are.

      In other systems, hard-to-varyness can be a bad thing. It's totally
      defined by how easily principles are added. IN metals, hard to vary
      means brittle. It can mean brittle for you too.
