Programs, devices and methods for estimating entrainment pressure within a group for a given behavior

摘要

To provide a program, etc., for estimating peer pressure in a group to a prescribed action.SOLUTION: Provided is a program for causing a computer to function that is installed in a device that estimates peer pressure in a group to the decision making of a user u from a plurality of other users u', the program causing the computer to function as: influence probability calculation means for calculating, for each user group, influence probability (u'|u), with regard to a prescribed action c, that indicates positional or attributional proximity; individual peer pressure calculation means for calculating, for each undecided user u not having made decision, individual peer pressure SP(u|Gma) received from each of other decided users u'(=1 thru Gma) having made decision; and group peer pressure calculation means for calculating group peer pressure SP(Gmi|Gma) by multiplying the sum of individual peer pressure SP(u|Gma) on all undecided users u(=1 thru Gma) in a group by a ratio of the number of decided users to the number of undecided users.SELECTED DRAWING: Figure 1
