Prediction
When I am dealing in future things, I am not free from prediction to explain what is going to happen. But the thing is that it is very hard to pick a correct one to match exactly what is happening in the future. And if I put a time frame into a consideration, it could be a lot more difficult than I imagine. So I am gathering all kinds of informations I can get to examine and to justify what possible outcomes would be like, based on maximum rationality I can possibly arrange. However, I am also fully aware that is not good enough all the times. Rather, I could be wrong any time soon.
But it does not mean I have to concentrate on a preference judgement unless that is a personal matter. It would be better off I put my efforts into developing precision up to a level I can reach, although I am not entitled to grab absoluteness out of it.
