Here is a passage from the Introduction to MADE TO STICK, by Chip Heath and Dan Heath. The text of the entire introduction can be found at

After this passage, I will give a few thoughts of my own about how this bears upon the challenge we are facing in dealing with this Bushite crisis.
Tappers and Listeners
In 1990, Elizabeth Newton earned a Ph.D. in psychology at Stanford by studying a simple game in which she assigned people to one of two roles: "tappers" or "listeners." Tappers received a list of twenty-five well-known songs, such as "Happy Birthday to You" and "The StarSpangled Banner." Each tapper was asked to pick a song and tap out the rhythm to a listener (by knocking on a table). The listener's job was to guess the song, based on the rhythm being tapped. (By the way, this experiment is fun to try at home if there's a good "listener" candidate nearby.)
But here's what made the result worthy of a dissertation in psychology. Before the listeners guessed the name of the song, Newton asked the tappers to predict the odds that the listeners would guess correctly. They predicted that the odds were 50 percent. The tappers got their message across 1 time in 40, but they thought they were getting their message across 1 time in 2. Why?
When a tapper taps, she is hearing the song in her head. Go ahead and try it for yourself — tap out "The Star-Spangled Banner." It's impossible to avoid hearing the tune in your head. Meanwhile, the listeners can't hear that tune — all they can hear is a bunch of disconnected taps, like a kind of bizarre Morse Code.
It's hard to be a tapper. The problem is that tappers have been given knowledge (the song title) that makes it impossible for them to imagine what it's like to lack that knowledge. When they're tapping, they can't imagine what it's like for the listeners to hear isolated taps rather than a song. This is the Curse of Knowledge. Once we know something, we find it hard to imagine what it was like not to know it. Our knowledge has "cursed" us. And it becomes difficult for us to share our knowledge with others, because we can't readily re-create our listeners' state of mind.
The tapper/listener experiment is reenacted every day across the world. The tappers and listeners are CEOs and frontline employees, teachers and students, politicians and voters, marketers and customers, writers and readers. All of these groups rely on ongoing communication, but, like the tappers and listeners, they suffer from enormous information imbalances.
The subtitle of MADE TO STICK is "Why Some Ideas Survive and Others Die." Or it might be put: Why some ideas catch on and others don't.
In general, I recommend this book, which is (and describes itself as being) a kind of successor the Gladwell's THE TIPPING POINT. (I read Gladwell's book around the time I was first getting ready to launch NoneSoBlind.)
In the specific passage quoted above, the Heath brothers are introducing the concept of "The Curse of Knowledge," and true to their own credo, they use a vivid and concrete example to bring the matter to life: the story of "The Tappers and the Listeners." The Tappers consistently over-estimate how readily the Listeners will recognize the Whole (the actual tune) to which the Tappers are alluding (through their rhythmic tapping.)
