I was thinking along the lines of words that carried the concept of implied doubt rather than requiring it through inference. I had been reading LessWrong and noticed someone talking in the comments about how the writing lacked nuance due to the need to make points clear. It got me thinking about the need for words that allow for this nuance in a way that doesn't disrupt flow. When I read the call to expand vocabulary I figured I would ask, since I felt my thoughts and his post were tangentially related. I'm sorry for not being as clear as I could have been.
