Let me start with this one. This is an old one but unfortunately (or fortunately) I only watched it recently. I watched it because I was talking to a friend about this author - Chimamanda Ngozi Adiche. She recommended her book- The Purple Hibiscus and Americanah, which is on my to-read list for this year. She is a young writer from Nigeria and this TED Talk was in July 2009 and is called 'The danger of a single story'.
This is such an eloquent presentation on something we all tend to experience (standing on either side) this in our everyday life- listening to a single side of a story. The agenda of 'someone' else is to share that single story and if we don't make that attempt to hear and look at the other side, we make our own assumptions. For instance, in this she takes us through her journey as a child and her interests in books and reading. It tells us how impressionable we are as people (more so as a kid) and every time we listen to only one side of the story, we make 'wrong' assumptions and sometimes even carry a prejudice that can change our way of looking at the world.
