... I don't think you finished your sentence, but what I'm saying is that people should be (and subconsciously are) always assigning a probability to every event, or at least every event that rises to the level of their attention, regardless of how little concrete information they have about its likelihood of occurrence. If they have very little information, or a lot of information, that will be reflected in the numerical value of that probability. If an event is very uncertain, it means that the probability should be very high in entropy.
