Here's a little piece of personal trivia for you -- my
husband is a screenwriter. So around our house there's no shortage of talk
about storytelling structure, and the bookcase is full of titles on the topic
like Joseph Campbell's classic The Hero with a Thousand Faces.
In short, I've heard a lot about the theory of how to spin a
great story. Which is why I found a recent blog post from psychologist and
author Susan Weinschenk so illuminating. In it, she delves not just into the
how of great storytelling but also the why -- why do these classic structures
affect us so profoundly? The answer, apparently, can be found in brain
chemistry.
