My undergraduate degree was in history from a top 10 university. Only say this to illustrate that I respect and love history. I thought I was going to become a historian. That said, the field has practical limits not faced by the hard sciences. You can’t test or prove your theories in History and many other humanities/social science. The best you can do is provide evidence that an event occurred. It’s the inherent limits of the field. How do you conclusively prove the cause of the French Revolution or the reasons the Japanese surrendered in WWII? So how can you validate that any reinterpretation is forward progress and not just a change?
