Nice post! I really enjoy thinking about the mind, if that's not some sort of oxymoron. It's true about choice and attention blindness. There have been studies that show people are happiest, most satisfied having chosen - i.e., having eliminated all their choices.
I wonder a little about a certain kind of preppy. The kind that's very into art - will major in it - but doesn't collect it. I wonder if that's a kind of paralysis brought on by the knowledge that there's so much out there.
But perhaps I digress... on the other hand, this kind of preppy also will show similar symptoms in their wardrobe. The clothing will be fine, but also... unimaginative, if I may be permitted to say so...
