ABSTRACT

It is often said that we live in uncertain times, or an uncertain world. One way to look at uncertainty is as a state of mind, in other words as the condition of being uncertain or having doubt. ‘Uncertain’ means not known or established, questionable, not determined, undecided, or not having sure knowledge. If, in most instances, a state of mind is the result of the environment, or, alternatively, the information we use to create this state of mind, ultimately it is information that can contribute to uncertainty or reduce it.
