Being a domesticated species, we’re most interested of all in the cause and effect of other people. We’re endlessly curious about them. What are they thinking? What are they plotting? Who do they love? Who do they hate? What are their secrets? What matters to them? Why does it matter? Are they an ally? Are they a threat? Why did they do that

The place of maximum curiosity – the zone in which storytellers play – is when people think they have some idea but aren’t quite sure. Brain scans reveal that curiosity begins as a little kick in the brain’s reward system: we crave to know the answer, or what happens next in the story,

The evolution of our strange, extremely other-obsessed brains has brought with it weird side-effects. Human obsession with faces is so fierce we see them almost anywhere: in fire; in clouds; down spooky corridors; in toast. We sense minds everywhere too. Just as the brain models the outside world it also builds models of minds. This skill, which is

When designing a character, it’s often useful to think of them in terms of their theory of control. How have they learned to control the world?

We experience our day-to-day lives in story mode. The brain creates a world for us to live in and populates it with allies and villains. It turns the chaos and bleakness of reality into a simple, hopeful tale, and at the centre it places its star – wonderful, precious me – who it sets on a series of goals that become the plots of our lives.

The mythologist Joseph Campbell said that ‘the only way you can describe a human being truly is by describing his imperfections.’

Meaning is created by just the right change-event happening to just the right person at just the right moment.
