Until recently we’ve only been able to speculate about story’s persuasive effects. But over the last several decades psychology has begun a serious study of how story affects the human mind. Results repeatedly show that our attitudes, fears, hopes, and values are strongly influenced by story. In fact, fiction seems to be more effective at changing beliefs than writing that is specifically designed to persuade through argument and evidence.
What is going on here? Why are we putty in a storyteller’s hands? The psychologists Melanie Green and Tim Brock argue that entering fictional worlds “radically alters the way information is processed.” Green and Brock’s studies shows that the more absorbed readers are in a story, the more the story changes them. Highly absorbed readers also detected significantly fewer “false notes” in stories—inaccuracies, missteps—than less transported readers. Importantly, it is not just that highly absorbed readers detected the false notes and didn’t care about them (as when we watch a pleasurably idiotic action film). They were unable to detect the false notes in the first place.
And, in this, there is an important lesson about the molding power of story. When we read dry, factual arguments, we read with our dukes up. We are critical and skeptical. But when we are absorbed in a story we drop our intellectual guard. We are moved emotionally and this seems to leave us defenseless.
