Whether it’s a sixty-word tabloid piece about a TV star’s tiara falling off or a 350,000-word epic such as Anna Karenina, every story you’ll ever hear amounts to ‘something changed’. Change is endlessly fascinating to brains. ‘Almost all perception is based on the detection of change’ says the neuroscientist Professor Sophie Scott. ‘Our perceptual systems basically don’t work unless there are changes to detect.’ In a stable environment, the brain is relatively calm. But when it detects change, that event is immediately registered as a surge of neural activity.
