Rationally Inattentive decision making extends general Bayesian statistical decision-making under uncertainty to the case when the decision maker has several options for obtaining extra information about the environment, before making optimal action based on all his information. In contrast to classic models of Bayesian decision making and in this framework, perception and action get into a reciprocal interaction. The term was first coined by Noble laureate Christopher Sims to develop a model to justify sluggish Macroeconomic adjustments in economics. However, general problem goes beyond and includes various situations encountered in the study of networked control systems, artificially intelligent and automated systems, brain and cognitive sciences and behavioral economics.
