Do you really understand why you last changed your mind? Ideas can change the world, but world-changing ideas can take many forms: political speeches, turns of phrase, ad campaigns, activist slogans, scientific theories, cultural tropes, and more.

In This Will Change Your Mind, we explore where persuasive new concepts come from, as well as how they move into wider culture, changing the ways we think and act.

Written and presented by Chiquita Paschal and Ian Steadman. Produced by Sarah Myles.
