There have been quite a few threads here in Social Sciences that would benefit from the inputs from sociology; for example, much of the discussion on 'race'. I personally am unfamiliar with the key theories in sociology, and the major themes, solid results, etc. However, here are some questions that I think sociology may have some interesting answers to: - how are social groups defined and identified? - what sorts of such groups are there (classification schemes)? - how do social groups form? - what are the key drivers of inter-social group behaviour? - what factors contribute to the rise, and continuation, of inter-group conflict? - ditto, decline and diminution? - what leads to the decline and disappearance of a social group? - how relevant are the words 'race', 'ethnic group', 'caste', 'class', etc? Surely sociologists have developed a set of terms, a framework within which to discuss their studies, so recasting the above questions in that framework may be a good first step.
