I suspect shared access to the conceptual referents of words would help with that specific problem, yes.
I suspect (with Feynman) that it would make only a small difference.
In particular, I suspect that if we did that we'd run more often into the currently-masked problem that everybody thinks about things a little bit wrong.

(People seem to differ in their interpretations of "telepathy," so I've started trying to develop the habit of Tabooing the word. The irony of this in the current context does not escape me.)
