Abstract
According to dual process theory, there are two systems in the mind: an intuitive and automatic System 1 and
a logical and effortful System 2. While many previous studies about number estimation have focused on simple
heuristics and automatic processes, the deliberative System 2 process has not been sufficiently studied. This study
focused on the System 2 process for large number estimation. First, we described an estimation process based
on participants’ verbal reports. The task, corresponding to the problem-solving process, consisted of creating
subgoals, retrieving values, and applying operations. Second, we investigated the influence of such deliberative
process by System 2 on intuitive estimation by System 1, using anchoring effects. The results of the experiment
showed that the System 2 process could mitigate anchoring effects.
