ABSTRACT
1 As decision rules and heuristics can be used as a technique for dealing with cases of complete ignorance of the initial probabilities of possible outcomes, the reader might be inclined to pitch his hopes for useful guidance a little higher. Again, I think he will be disappointed. But before pronouncing judgement, we shall illustrate with one or two simple examples represented as payoff matrices, where the choice of the projects is to be made given the payoffs that are dependent on varying states of events.
