The foregoing modifications to epistemic logic fall broadly within the scope of the subject which has come to be known as bounded rationality – c.f., e.g., (Simon 1957; Simon 1972; Rubinstein 1998; Gigerenzer and Selten 2002; Kahneman 2003). This development can be traced to work in decision theory and cognitive psychology which attempts to take into account that human agents face resource limitations in everyday decision making. The attempt to develop models of decision which take resource limitations into account is sometimes presented as a counterpoint to the normative models of rational choice which are often employed in economics and political science. In this context, decision making is often modeled as a form of optimization. In particular, it is traditionally required that fully rational agents be able to find an optimal choice among an array of alternatives,  the potential infeasibility of carrying out a search amongst them notwithstanding.
