This is an example of an out-of-sample problem. As easy as it might seem to avoid this sort of problem, the ratings agencies made just this mistake. Moody’s estimated the extent to which mortgage defaults were correlated with one another by building a model from past data – specifically, they looked at American housing data going back to about the 1980s.

Nate Silver Quotes

Who needs theory when you have so much information? But this is categorically the wrong attitude to take toward forecasting, especially in a field like economics where the data is so noisy. Statistical inferences are much stronger when backed up by theory or at least some deeper thinking about their root causes.

The most basic tenet of chaos theory is that a small change in initial conditions – a butterfly flapping its wings in Brazil – can produce a large and unexpected divergence in outcomes – a tornado in Texas. This does not mean that the behavior of the system is random, as the term “chaos” might seem to imply. Nor.

What makes them so tragic is the gap between what his characters might like to accomplish and what fate provides to them. The idea of controlling one’s fate seemed to have become part of the human consciousness by Shakespeare’s time – but not yet the competencies to achieve that end.

I lived the poker dream for a while, and then it died. I learned that poker sits at the muddy confluence of the signal and the noise. My years in the game taught me a great deal about the role that chance plays in our lives and the delusions it can produce when we seek to understand the world and predict its course.

The way to become more objective is to recognize the influence that our assumptions play in our forecasts and to question ourselves about them.

Scientific progress is harder to measure than economic progress.32 But one mark of it is the number of patents produced, especially relative to the investment in research and development. If it has become cheaper to produce a new invention, this suggests that we are using our information wisely and are forging it into knowledge.

In any contentious debate, some people will find it advantageous to align themselves with the crowd, while a smaller number will come to see themselves as persecuted outsiders. This may especially hold in a field like climate science, where the data is noisy and the predictions are hard to experience in a visceral way. And it may be especially common in the United States, which is admirably independent-minded.
