I was going to link you to the q @gailcalled alerted you to. Just in case, I’ll repost my answer
As a social scientist (my future) and a person of biology and scientific research (my past), I can understand your criticism – it’s thrown around a lot in academic circles, this kind of attempt to discredit – however, as you note, the umbrella of social science covers a lot of areas that do utilize the ‘scientific method’ and all the ‘rigorous’ aspects that come with it. The early pioneers you mention understood that science, to them (and to me), didn’t just mean ‘get to facts using hypotheses, etc.’ because it was social science and wasn’t always having to do with questions that can be addressed that way. I like this part from wiki:
“The term may be used, however, in the specific context of referring to the original science of society established in 19th century sociology. Émile Durkheim, Karl Marx and Max Weber are typically cited as the principal architects of modern social science by this definition.[4] Positivist social scientists use methods resembling those of the natural sciences as tools for understanding society, and so define science in its stricter modern sense. Interpretivist social scientists, by contrast, may use social critique or symbolic interpretation rather than constructing empirically falsifiable theories, and thus treat science in its broader classical sense. In modern academic practice researchers are often eclectic, using multiple methodologies (for instance, by combining quantitative and qualitative techniques).”
I think that no social scientist should put forth conclusions and state that they arrived at that conclusion using the scientific method if that wasn’t the method they used. However, I don’t think many social scientists do that – just like ‘normal’ scientists, they put forth theories about humanity, about societal patterns and understand that ultimately much of it is conjecture but the importance of the contribution of social science to me is invaluable. As a sociologist, I firmly believe that ‘regular’ science was NEVER objective in its trajectories and to this very day carries with it all the flaws of humans – that’s why many scientific ‘truths’ can be questioned by sociologists because there are social forces shaping science, affecting scientists and each period of discovery needs to be assessed within its social context. For example, my future research will be grounded on the work of social scientists who work on addressing evidence out there claiming to show sex differences between men and women – as it so happens, it is the regular scientists, in this contested topic, that are using VERY shady science, straight down to lies, which then gets disseminated to people and affects policy and educational options, etc. It is the social scientists in this field that have taken the task of debunking their faulty methodology, of asking about correct scientific method and whether all the steps were followed. So I am glad to be part of a field that often keeps the ‘objective’ scientists in check. Though, I call myself a sociologist rather than a social scientist because the emphasis, at least for me, is on the social rather than the science – but you will never hear me proclaim otherwise.
