Keep concepts stable
When discussing a potentially difficult topic, it can be easy to have an idea be a poorly defined pointer to concept-space. This is inevitable, and why we use intentionally ambiguous naming to avoid restricting growing or uncertain ideas, for example.
However, even if there is ambiguity or uncertainty in a given section of concept-space, we should still seek to keep that words are pointers to concept-space stable. This allows us to avoid the fallacy of compression.
