Blink: The Power of Thinking Without Thinking by Malcom Gladwell

I heard Daniel Negreanu say during the WSOP ME webcast that he was reading this book. I picked it up and found it very interesting with applications in poker decision-making.
Blink pertains to the act of decision-making and how snap judgments made under stress by our unconscious minds are sometimes very reliable. Our unconscious mind weeds through the extraneous information and zeroes in on the pertinent information. We know something, but we don't know why we know it.
I'm reading the book now, and it reminds me of those gut instincts poker players get when they just know a guy is bluffing or not. It's a skill that can be developed.
If anyone else has read it, I'm curious what you think.
