Why vague may be better than precise

In the past I've wondered why communications among the key players in the CME community tend to be so vague and open to interpretation. Just today I ran across an article that further helped me better understand why sometimes it's actually beneficial to keep it vague: Read Wired's In Praise of Vagueness. This sums up the main point:

"Sometimes, precision is dangerous, a closed door keeping us from imagining new possibilities. Vagueness is that door flung wide open, a reminder that we don’t yet know the answer, that we might still get better." Which is basically what Dr. Kopelow has said to me when I've asked him to get specific on some of the finer points of ACCME regulations. I get it. It's still frustrating, but I get it.
