The world is changing at an incredible speed. No matter whether in the social, political, economic or technological field; the upheavals that have ushered in the Age of Collective Individualism are so enormous that they ultimately raise the question of whether human beings themselves have not also adapted or developed as a result. This book affirms this and, with the theory of Homo stimulus, would like to offer a first basis for discussion about a possible conditioning of human individuals, in an epoch characterized by Stimulus Society and Behavioral Capitalism.
