" Denning says that the idea of telling stories initially violated his intuition. He had always believed in the value of being direct, and he worried that stories were too ambiguous, too peripheral, too anecdotal. He thought, “Why not spell out the message17 directly? Why go to the trouble and difficulty of trying to elicit the listener’s thinking indirectly, when it would be so much simpler if I come straight out in an abstract directive? Why not hit the listeners between the eyes?” The problem is that when you hit listeners between the eyes they respond by fighting back. The way you deliver a message to them is a cue to how they should react. If you make an argument, you’re implicitly asking them to evaluate your argument—judge it, debate it, criticize it—and then argue back, at least in their minds. But with a story, Denning argues, you engage the audience—you are involving people with the idea, asking them to participate with you. "
