Information search and mental representation in risky decision making: The advantages first principle

Abstract:In three experiments the problem is investigated how people identify early in the decision process those alternatives that are worthwhile to be examined in more detail. We assume that decision makers employ the Advantages first Principle: They first search for information about positive outcomes and then focus their information search (e.g., for negative consequences or for risk defusing operators) on those alternatives that appear attractive after this initial evaluation. In Experiment 1 (120 participants), initial information about consequences was varied for eight alternatives (no information, positive consequences, negative, or mixed for four alternatives). In all conditions, the great majority of participants followed both aspects of the Advantages first Principle. In Experiment 2, 60 participants decided in two quasi‐realistic scenarios with two alternatives each. Initial information was presented so that one alternative had better positive consequences, worse negative consequences, or both. In all conditions, more information was searched for in the initially better alternative. In Experiment 3 (20 participants) the Advantages first Principle was not only confirmed for a scenario but also for choices in traditional gambling tasks with two and eight alternatives, respectively. Participants could win or lose real money. Copyright © 2010 John Wiley & Sons, Ltd.
