Why are some people racist and judge others by the colour of their skin? Is it some deep seated fear of the ‘other’ which has roots in genetic and cultural difference or are exposure to artificial factors constructed by politicians and the media to blame?

This week's Why Factor with presenter Jo Fidgeon explores the experience of racism around the world and in different societies. She finds out about the personal experiences of racism and how it affects peoples’ everyday lives. She also begins to understand how racism is perpetuated through generations and cemented through institutional racism.
