Explaining routinized decision making -: A review of theories and models

We review theories of preferential decision making and apply them to explain and predict the choices made by experienced individuals. Specifically, we focus on decision problems for which the actor already has a potential solution or routine available. We start with a brief overview of research evidencing the manifold ways in which such routines can influence the decision-making process. We then develop a classification of decision theories and examine their explanatory power, that is, the extent to which they can give post hoc explanations for routine effects. Finally, we narrow the analysis down to those theories that explicitly address routinized decision making and examine to what extent they are able to make a-priori predictions of routinized decision making. The review reveals that the arsenal of theories as a whole possesses a high potential to derive posthoc explanations of routine effects with the help of some auxiliary assumptions. However, there are only a few decision theories that explicitly incorporate the influence of routines on choice. Examination of their predictive power reveals that we currently are not able to precisely predict information search, evaluation and context influences on choice in routinized decision making.
