To judge a person's constitution precisely by a computer.

The system presents to a user a constitution judgement table (S31 and S33) and, based on the result of answers by the user to the questions listed in the constitution judgement table, selects one of the ranks to quantify an intensity of tendency which the user shows for contents of each item with regard to each of a plurality of items with which judge the user's constitution and display it (S32 and S34). Further the system calculates points by rank according to the result of selection of rank for each item and according to an allotment of points given to each rank at the time of selection beforehand and sums up a plurality of points calculated for each rank of all the items (S35 and S37). According to what is a distribution pattern of a plurality of total points obtained in that manner and reflects a state of dispersion of the plurality of total points, the system classifies the users' constitution into one of the plurality of predetermined types and makes a judgement (S36 and S38).
