That is a very good question Donuel. I would not advocate for History as a social science, or any other kind of science. But I would strongly recommend that anyone seriously contemplating the study of history enroll in a school that has a rigorous department of studies in historical research methods. I have taught a course of this nature and many students find it difficult at first, but once they become adept at recognizing their own biases and illiminating them, they find the research and writing of history much more satisfying.
I have a great respect for the study and research methods of Science, but I think that the study of science is quite different from the study of history, although there are some basic rules to be applied in the study any discipline.
What I often see in these threads are comments by people who really don't seem to read much history and perhaps do not understand that it is a discipline and how hard one must work at it.
