I’d say you’re not using the right filtering, which honestly takes a lot of practice and sheer luck.
Usually if I get garbage results, I try neuroscience -“top 10”, which would remove the generic top 10 reasons for X results. If it’s still self help garbage, then try more keywords like lecture, presentation, or theory. Some searches I straight up can’t figure out though, and the query ends up removing being a mess. In those cases, it’s worth trying again later and seeing if you’ve phrased it won’t.
Yeah there’s a lot of foreign influence, some of it successful as well:
