We librarians already know this. That’s why people love looking at the books behind the circulation desk that have just been checked in. Someone already made the choice to check out those books. It doesn’t matter if it was a bad choice, because sometimes just not having to make a choice is what is important! Do your book displays prevent people from having to make a choice? Are they as novel as the Yellow Books Display? Do you have 3 sub-menus though which your web users must drill down?
Still not convinced that choice can hurt and make people feel stupid? Take a look at this configuration of Firefox! Egads.
