ABSTRACT
It can be argued that when choosing the best from among the survivors of screening (the choice set) the decision maker should use all that he or she knows about each option’s attributes. What the decision maker knows includes both what was known at the time screening took place as well as whatever has been learned since then. However, it is not difficult to imagine decision makers failing to behave in this way. They may assume that because the members of the choice set all survived screening, the criteria used for screening must have been met, and therefore those criteria cannot be used to further differentiate among the survivors. However, convenient though this assumption may be, it does not wholly justify ignoring the relative amounts to which the survivors satisfied the screening criteria when the time comes for prechoice evaluations and the final choice of the best option.
