A diminished attentiveness state prediction system comprising: an eyeball movement/eyelid activity measurement unit that measures eyeball movement and eyelid activity of a subject, and obtains eyeball movement/eyelid activity data; an interval assessment unit that assesses an open-eye interval, a closed-eye interval, a blink interval, and a repeated occurrence interval on the basis of the eyeball movement/eyelid activity data; an eyeball movement/eyelid activity-related information calculation unit that calculates the microsaccade frequencies, etc., of the open-eye interval on the basis of the eyeball movement/eyelid activity data; and an attentiveness evaluation unit that determines an attentiveness evaluation, etc., for the open-eye interval, and an open-eye/repeated occurrence interval, which is the repeated occurrence interval, based on the microsaccade frequencies, etc.
