thank you. >>> george lakov has been studying political messaging for years. he's a linguist at uc berkeley. he joins us to talk about how democrats and progressives are confused. linguistically, size up donald trump for me. >> he knows how not just to speak, but how to change your brain and effect your brain. he's a super salesman, and he's very good at it, and you need to know a little bit about your brain. ideas don't float in the air, if you have a world view, your understanding of the world in general, then that's a lot of neural circuits. those neural circuits are fixed. once they're fixed, they become what you might call a neural filter, you can only understand what your brain allows you to understand. if you have only one world view, you're stuck to understand things that fit that world view. and if information comes in that doesn't fit it, it will be either not noticed, ignored, ridiculed or attacked. >> people choose to have one world view? >> not necessarily. a lot of times they're brought up with it. >> he could expand his world view if he wanted t

we're glad you joined us, george lakov in a moment.
