Risk taking by decision makers–using card-based decision gaming to develop models of behaviour

This paper describes an experimental method for determining the value of different types of information to military decision makers. The experimental method used a simple scenario and a set of serials constructed from cards, each presenting a single piece of information and presented sequentially. Each of a number of pairs of players were taken through the scenario and asked to judge how they would respond to the situation. This paper extends on the method presented in previous papers to consider the case of a decision in which the response can both increase and decrease as more information is presented. This allows a more general military problem to be considered, that of risk-taking behaviour in response to the possibility of chemical, biological, radiological or nuclear events.
