Blink

Striker, a reviewer for Amazon from India writes:
Gladwell says, "A world where snap judgments and thin-slicing is taken seriously is a better place." I know some people who might object to that viewpoint, particularly when it comes to decision-making in foreign policy, but if you want an entertaining read, fast-paced, rich in entertaining anecdotes and some unusual scientific research, then BLINK is worth picking up.

I am loving Blink. It basically explains how, when we tap into our/the subconscious, we access really profound knowledge. He illustrates how trustworthy these gut feelings are (what he refers to as 'thin slicing').
He also shows where and when we are accessing the subconscious, how to do it, and why to trust it. Very useful.
