Malcolm Gladwell 3: The unheard story of David and Goliath

TEDSalon NY 2013
Malcolm Gladwell 3: The unheard story of David and Goliath (script)

Summary 

Underdog means the person or team considered to be the weakest and the least likely to win.
In the world, people like the story that underdog wins somehow. They are attracted by its victory as improbable.
Even in the Bible, there is a tale that underdog wins.
A young shepherd, David, doesn't look strong. He doesn't have arms and armor.
Goliath is a warrior. He is a giant, he wears in bronze armor and has a sword with his hand.
People think that a shepherd is weaker and underdog but they assume that he can't win. Then they can't think about the fact that a young shepherd has won well. It means that the true reasons are undermined and a wonderful story is born.
The speaker tells us that people have only judged by appearance before. In fact, there has been the rest of the story that we have unheard.
Judging by appearance, your apparent strength is, in fact, the source of your greatest weakness and you might have a sling in your pocket.
These will be as true of us always.
