QUOTE : Archaeology is a deeply conservative discipline and I have found that archaeologists, no matter where they are working, have a horror of questioning anything their predecessors and peers have already announced to be true. They run a very real risk of jeopardizing their careers if they do. In consequence they focus--perhaps to a large extent subconsciously--on evidence and arguments that don't upset the applecart. There might be room for some tinkering around the edges, some refinement of orthodox ideas, but God forbid that anything should be discovered that might seriously undermine the established paradigm.
