This exciting and original work is the first to apply cognitive linguistics to the analysis of political lies and conspiracy theories, both of which have flourished in the internet age and which many argue are threatening democracy. It unravels the verbal mechanisms that make these "different truths" so effective and proliferative, dissecting the verbal structures (metaphor, irony, connotative implications etc) of the words of a variety of real-life cases in the form of politicians, conspiracy theorists and influencers. Marcel Danesi goes on to demonstrate how these linguistic structures "switch on" or "switch off" alternative mind worlds.
