Interestingly, human irrationality is a hot topic in economics at the moment. Behavioural economics it's called, on the cusp of economics and psychology.

It's a very hot topic.

Put simply, behavioural economics argues that human beings' decision-taking is guided by the evolutionary baggage which we bring with us to the present day. Evolution has made us rational to a point, but not perfectly so. It has given us emotions, for example, which programme us to override our rational brain and act more instinctively.

Someday we'll look back on this moment and plow into a parked car.

I actually profoundly think the world's a better place when economics is fairly boring... The more boring the better.

But beginners to the World Economics Forum have to understand there is no single Davos experience, and there is no single Davos community either. There are numerous tribes who interact only at a minimal level.
