Single Story

While listening to the TED talk I found myself both agreeing and disagreeing with this idea of a "single story". Initially I agreed because frequently there are single stories or party lines that get fed to us and when you actually research the topic you find out that there were a million other voices that got ignored in favor of one idea. However, it was that thought that made me question the conclusion even as I came to it. Is an idea a "single story" of sorts? When you hear an idea or story don't you automatically internalize it in one way or another and make it different? Even if it's just the difference between laughing at something or not, or agreeing with a statement or remaining silent--doesn't that change the way other people see it (or hear it, read it, etc.)?
