The premise here, that there is some underlying objective version of reality when it comes to consuming works of art (wine, food at restaurants, TV images, or even haircuts.) is extremely flawed. This article is like comparing the price of haircuts to the amount of hair removed. Yes, there is a metric, but I'm not sure it has meaning.
You drink wine or eat in a nice restaurant for the experience you receive, not for where the food comes from. Expectations are part of that experience, sure, but trying to assign it all to "expectations" is just a rhetorical dodge. How can anything experiential not involve expectations? It can't. It's ludicrous to think otherwise.
These things are not evidence of you not being so smart, they are evidence of the wonderful experiential nature of being alive. Isn't it great that we can plan and dream about a very inexpensive upcoming trip to the mountains and end up having a better time than somebody who spent 100 times as much for a much longer holiday? Or that we can spend an extra 40 dollars on a bottle of wine and imagine how much better the experience will be -- thereby increasing our eventual enjoyment? There's nothing dumb or not-so-smart about this. This is the human experience. Anybody who has ever spent any time around children understands that this subjectivity is a huge part of our makeup. In fact, to suppose that somehow this would be news to anyone is to assume the audience thinks of themselves as super-rational machines. Perhaps that's the problem: I'm not a member of the target audience. Still, I didn't like it. These books are the kinds you read and end up thinking "People are really broken! They are pretty stupid!" which is most likely the same damn thing you thought before you picked up the book in the first place.
