For example, you might use them to determine whether smoking causes cancer, or carbon dioxide causes global warming – or more locally, whether cutting Universal Credit reduces unemployment.

The brain has evolved to seek out cause-and-effect relations in the world around us, and assemble them into a graph just like this. It learns the relationships by obser…
