Noted sociologist of religion Grace Davie gives a brief description of her work:

My work, like that of all social scientists, rests on the assumption that human living is not random. Why is it, for example, that Christian churches in the West are disproportionately attended by women? That requires an explanation.

This is a good starting point for describing the social sciences. There are patterns to human social life and we can’t rely on anecdotes or interpretations of whether there are patterns or how to understand them. We want to apply a scientific perspective to these patterns and explain why those patterns, and not others, exist. Then, we might delve deeper into level of analysis, theoretical assumptions, and techniques of data collection and analysis – three areas where the various social science disciplines differ.
