[Problem] In the past, it has not been possible to detect objects that are experienced similarly by people, on the basis of potential awareness. [Solution] This brain information processing device is provided with: a receiving unit that stores one or more items of brain information that includes brain activity information, which pertains to the activity level of a brain when objects are shown to a subject, and object information pertaining to the objects, and receives the brain activity information pertaining to the activity level of the brain when the objects are seen by the subject; an object information acquisition unit that acquires one or more items of object information corresponding to one or more items of brain activity information, which approximates the brain activity information enough to satisfy a predetermined condition; and an output unit that outputs the object information acquired by the object information acquisition unit. The brain information processing device uses information for advanced brain activity indicating potential awareness to detect objects that are experienced similarly by people.
