Thanks to elegant research from some of the best scientists in the world, we are finally beginning to understand why stories wield unique significance for Homo sapiens - including why our brains are able to comprehend them in the first place.

If you have ever watched a child act out a story, you have observed something exceptional about the impact of stories on human behavior. Not only do we understand them, we move our bodies and limbs in tandem with the stories in our minds – even if, as is often the case, we know them not to be true. No other animal, so far as we know, possesses this remarkable trait.

The human relationship between story and behavior sheds new light on the question of whether a particular story is true or false. Better to ask - is it effective? If it motivates behavior, and that behavior impacts the individual and/or others, then the story is of consequence.

But stories aren't just play things. They are the root of our religions, nations, and the precious possessions of our cultures. We may sacrifice much in life, but we will often live and die for the right story. To understand why, we need to take a deeper look into how stories take up residence in our brains, and what happens when they depart. This is your brain on stories.
