Thanks for the phrase "incessant overgeneralization" -- I didn't even realize I was looking for that. It seems that this is something the social sciences are inherently at risk of, given how closely the topics are to our everday lives.
In the hard sciences, for example, the problems that people work on are often less complex and more removed from everyday human life. I think this causes for much less over-generalization to occur.
Over-generalization is common beyond the social sciences as well. It is often found in the basis given for false dichotomies, which are not uncommon in discussions of how to write software. It is also apparent in many of the claims made by clickbait titles.
