You're supposed to have a probability for everything. The closest you can do to not guessing is give every possibility equal probabilities, in which case you'd lose honor even faster than normal.

You could give yourself honor equal to the square of the probability you gave, but that means you'd have incentive to phrase it in as many questions possible. After all, if you gave a single probability for what happens for your entire life, you couldn't get more than one point of honor. With the system I mentioned first, you'd lose exactly the same honor.
