Human brains are hardwired to believe lies and conspiracy theories that have been brought about by politicians, dictators and social disruptors, according to a new book that analyses the power of language on people’s brains.

The book "Politics, Lies and Conspiracy Theories", by Marcel Danesi Professor of Semiotics and Linguistic Anthropology at the University of Toronto, Canada, analyses the speeches of dictators including Mussolini, Stalin, and Hitler, as well as prominent hate groups.
