Michael Rosen and Dr Laura Wright interview the eminent US linguist George Lakoff about the new political words coming out of the US right now, mainly from the alt-right, and the effectiveness of Trump's use of language. George Lakoff is the former Distinguished Professor of Cognitive Science and Linguistics at the University of California at Berkeley. His thesis is that people's lives are significantly influenced by the central metaphors they use, whatever their political beliefs, and that how information is framed is crucial in how it is received.
