Haidt, Chapter 3

Chapter 3 has many more examples of how people reach snap judgments.  The most interesting experiment, though, is the one at the end:  Instead of letting people respond to a moral dilemma (and an argument about the dilemma) right away, the experimenters forced people to wait 2 minutes before responding to the argument about the dilemma.  People actually changed their minds when they paused to think.  Besides being a hopeful statement about human nature in general, it's also a counter to the zeitgeist about the power of our subconscious.
