From an article in the New York Times on the new Museum of the American Revolution just before it opened in Philadelphia:

“We’re trying to take a page from science museums, which are better than history museums generally about asking questions of visitors, and being more interested in raising questions than providing answers,” said R. Scott Stephenson, the [Museum of the American Revolution's] vice president for collections, exhibitions and programming. “Usually with a history museum, it’s more like history as found facts. This is more like: ‘Dinosaurs: Are they like birds or reptiles? Let’s look at the evidence.’”
