Does form follow function?

When you look at the outside of a building, can you tell whether it is an art museum, or a library, or a theater? Most people can't.
A recent study shows that many modern public buildings no longer follow the famous rule in architecture: form follows function. The idea behind this rule is that people should be able to understand the purpose of a building, its function, from the way it looks, its form.

The researchers in the study believe that when buildings clearly show their purpose, visitors can more easily find their way, and city life is more comfortable and understandable for everyone. Some architects today are more interested in designing buildings to catch out attention than to tell people what goes on inside.
