Abstract

While Rational Choice Theory (RC) may be understood as a theory of choice, which does not necessarily reflect actual deliberative processes, rule-following behavior is definitely based on a certain form of delibera- tion. This article aims at clarifying the relationship between the two. Being guided by instrumental rules, i.e., rules reducible to the maximiza- tion principle, is perfectly consistent with the fundamental behavioral assumptions of RC. But human individuals use other forms of rules in decision making, especially tie-breaking rules and coordination rules. It is argued that within RC no satisfying account of such rule-following behav- ior can be given. In particular it is impossible to determine suitable pref- erence orderings such that coordinating may be understood as maximizing relative to these orderings. Still, once there is coordination, following a coordination rule may be perfectly consistent with the basic assumptions of RC. So there might be a more complex theory of action that incorpo- rates RC as well as a satisfying theory of rule-guided behavior.
