You're listening to "Our Inhuman Condition", the podcast where we shine a light onto a simple but ultimately troubling question: why do ordinary people do evil things? In this episode, we're going to look at Dehumanisation - how it happens, why it happens and how it has led to some of humanity's darkest days. To answer these questions, we're going to visit hospital wards, Trump rallies, volcanoes and chair factories (?).
