Talk to a randomly selected group about libraries and you will get the same 'ole ideas. That's why librarians have to tell people what to think about libraries.Every so often some very talented visionary will echo the statement that they don’t listen to focus groups or conduct market research because people don’t know what they want. I think that this idea can be applied on the ground as much as in far-off visions of very smart people. One doesn’t have to be ahead of his time to realize that non-experts or amateurs are often totally clueless and/or grossly misinformed about a given subject or occupation. Many times, these folks will even overestimate their competence or knowledge of the item under consideration..
