Yeah, as science I have serious doubts about sociology. As a way to form an ontology it's plausibly worse than vernacular tradition. Please prove me wrong and point me to high quality sociological studies. I want to believe we have practical tools to deal with the future of our species.
This is just an example of a well-known recent sociology paper that can appeal to science-minded people unfamiliar with sociology.
By the way, it's a danger to rely too much on mathematical formalism as a heuristic for deciding whether a research field is scientific or valid. String theory for example lacks empirical evidence (and maybe even the possibility of empirical validation altogether).
In general I agree. However many studies in this field had been large scale enough with low variance that effect is not ignorable. Given similar results, it appears reproducibility is also high.
