Meanwhile in China, there are numerous article-factory-journals that are pay to publish, you can put your shoddy work in those and amp up your publication count easily. Surely, these exist in the USA, but are career scientists at major institutions utilizing these shady Chinese journals? There is evidence that some of these Chinese journals are publishing straight up BS, which is especially easy to do with data analysis where you could "clean" your data easily. Perhaps it is a cultural or political difference, but I don't see nearly as much rigorous self-reflection of Chinese scientists on this front?
Second issue, grants: publications are a small slice of this story. Science departments (not humanities) in universities are MAJOR revenue generators for the University. My university took 1/3 of your grant straight off the bat, to cover overheads like shiny facilities and administration and marketing. Meanwhile, the scientists themselves may make huge salary bonuses or advance their tech/staff substantially when they have substantial grants. So, getting a grant is great for you personally, and improves your chances of further grants.
So, is it really that surprising that there may be pressure to publish at all costs, to p-hack, to reach for those low-impact journals despite their lower reputation/impact, given both universities and scientists are BOTH massively financially benefited from this incrementalism? Does it really pay to reach for pie-in-the-sky, fundamental sea-changes in your field? It seems like a high variance, high risk strategy that only very bold, well-funded, devil-may-care scientists would employ.
