The book maps the impact of conspiracy theories at the international political level.It shows how a conspiracy theory travels from the sender through communication channels to the receiver, influencing the processes of construction and deconstruction of the interpretation of the surrounding reality. It therefore serves as an instrument of information warfare to create international advantage, generate profits, or achieve ideological goals. The book presents academic reflection on a socially important problem – conspiracy theories, their patterns of dissemination, and their impact on identity formation.This book is of key interest to scholars and students of conspiracy theories, global governance, global security, international studies/ relations, and social psychology.
