Malcolm Gladwell spoke a couple of years ago at a conference I attended and I was hooked. He has an original way of looking at the world that makes you re-evaluate what you believe and have accepted as fact.
One of my favorite quotes is, "But what I have sensed is an enormous frustration with the unexpected costs of knowing too much, of being inundated with information. We have come to confuse information with understanding."
So maybe we can learn from Gladwell how to encourage practical problem solving without getting into the bind of always having to have more information.
