Confirmation bias, which refers to unintentional and unknowing selectivity in the use of evidence, belongs to the major problems faced by organizations. In this article, we discuss job rotation as a natural solution to this problem. In a nutshell, adopting job rotation provides an organization that is plagued by confirmation bias with a more reliable informational footing upon which to base its decisions. Job rotation, however, also comes with a cost, e.g. a loss of productivity or a disruption of work flows. We study this trade-off and identify conditions under which job rotation and specialization are each optimal.
