Abstract: An analysis that allows intuitively grasping a difference between an action of by analysis target person and an action by another task executor is achieved. There is provided an information processing device including an analysis unit that analyzes a tendency of a preference related to an action on the basis of action result data indicating a result of the action regarding a predetermined task, in which the analysis unit generates a similarity map representing a similarity between the actions by each of a plurality of task executors including an analysis target person on a two-dimensional plane on the basis of the action result data, and represents strength of a preference related to a type of the action selected in a heat map form in the similarity map.
