None of the terms of euphemisms for anything.
People anticipate the future by developing and employing models of what is going on.
One can be certain either because certainty is warranted or because it is unwarranted. If certainty is warranted, then there are not going to be any discrepencies that matter between the anticipated state and the actual state when it occurs. For the particular area of concern, the world works in a regular and predictable way, AND the person concerned with the outcome has the information and cognitive capabilities required to work out what the predictable outcome is. That is, there has to be both ontological and epistemological basis for that certainty. So epistemological uncertainty is probably the most strategic line of attack.
