We are all addicted to forecasts. The soothsayer, the oracle, and the entrails of chickens played their allotted role in supposedly divining the future in more primitive times. Today, we may laugh at these displays of superstition. Yet, we seem to take seriously those "experts", who purport to make forecasts of climate change over the next thirty years, or of the economy and financial markets over the next twelve months, or even two years.
