Chapter 8: On the Origins of Propaganda: Bio-Cultural and Evolutionary Perspectives on Social Cohesion

This chapter recasts propaganda as a socially evolved trait that helps to establish identity and social cohesion. Propaganda emerged as the organization of human groups grew beyond those linked by genetic kinship and toward ones connected by shared ideas and beliefs. By generating cognitive dissonance, propaganda builds upon a reliance on identity systems. Experiments that examine the neurotransmitters oyxtocin, vasopressin and serotonin provides a physiological explanation for the effects of propaganda. This chapter illuminates the use of propaganda in constructive memory formation, altruistic punishment, recursion, diplomatic speech, advertising, and many other forms of socialization.
