Rather than poor theory of mind what about good understanding of economics. The cost of absolutely clear context is too high to bear in many situation, it is often better to get the message across in whatever way works for those who are also in the know.. that way collaboration can cheapen the cost of constructing context. Of course if there is an off-the-shelf context available that you can refer to then there is no communication problem in the first place.
