- maybe being better at breaking new intellectual ground requires some kind of ability that can also be applied to explaining things? like maybe some people are just smarter than others, either inherently or as a result of their training and experience, in a way that generalizes to both tasks
- maybe the things that most strongly impede people from breaking new intellectual ground also impede them from explaining them clearly? candidates might include emotional insecurity, unthinking devotion to tradition, and intellectual vanity (wanting to look right rather than be right)
- maybe the people who suck at explaining their own ideas don't get access to the cutting-edge developments that they would need to break new intellectual ground? shannon had the great good fortune, for example, to spend a lot of the war at bell labs conducting cryptanalysis, rather than sleeping under a dunghill on the battlefield or on the assembly line making artillery shells
