Abstract

According to the dual process theory, there are two systems in the mind: an intuitive and automatic System 1 and a logical and effortful System 2. This study focused on the System 2 process for large number estimation. First, we constructed a process model of estimation. The model, corresponding to the problem-solving process, consisted of creating subgoals (System 2), retrieving values (System 1), and applying operations (System 2). Additionally, a knowledge network was used for the estimation process. Second, the results of an experiment based on our model showed that the deliberative System 2 process did not improve the value estimated by the intuitive System 1 process.
