Psychology Today reveals how storytelling helps persuasion.
Peter Guber writes (excerpt):
[T]elling purposeful stories is certainly the most efficient means of persuasion in everyday life, the most effective way of translating ideas into action . . . .
. . . Stories, on the other hand, are state-of-the-heart technology—they connect us to others. They provide emotional transportation, moving people to take action on your cause because they can very quickly come to psychologically identify with the characters in a narrative or share an experience—courtesy of the images evoked in the telling.
