Quotables from Nate Silver:
our early estimates ... weren’t based on a statistical model. Instead, they were what we [call] “subjective odds” — which is to say, educated guesses. In other words, we were basically acting like pundits, but attaching numbers to our estimates. And we succumbed to some of the same biases that pundits often suffer, such as not changing our minds quickly enough in the face of new evidence. Without a model as a fortification, we found ourselves rambling around the countryside like all the other pundit-barbarians, randomly setting fire to things.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
