Humans don’t always behave as you expect them to. Sometimes their responses and actions are completely irrational – we don’t always make perfect decisions – but the model we base everything on is a rational one. Why? If we design our systems, our government, and all the products and services we use for perfect, rational people, is it any wonder they aren’t working? The Stanford academic and political advisor believes that change is possible and necessary: that we can create a more local, more accountable, more human way of living that will make us more productive, more fulfilled and ultimately happier.
