You can build a statistical model and that's all well and good, but if you're dealing with a new type of financial instrument, for example, or a new type of situation - then the choices you're making are pretty arbitrary in a lot of respects.

I think a lot of journal articles should really be blogs.

I actually buy the paper version of The New York Times maybe once or twice a week.

I think people feel like there are all these things in our lives that we don't really have control over.

Midterm elections can be dreadfully boring, unfortunately.

The problem is that when polls are wrong, they tend to be wrong in the same direction. If they miss in New Hampshire, for instance, they all miss on the same mistake.

A lot of things can't be modeled very well.
