On the whole you should rarely read papers, you want to read a whole literature in an area. Academics embedded in the field can do this easily. Academics outside of an area know to do this, and to bounce things off an expert to make sure you have the context and aren't over-indexing on a flashy result. Everybody learns the painful lesson in grad school to not just read a paper and believe everything will work as it says.

Somehow the general public and policymakers got the idea that if a paper gets published in any non-fake journal, this is an official endorsement that it's 100% correct, everything in it can be read in isolation, and it's safe to use all claims in the paper to direct policy immediately.

I think academia is partially to blame for encouraging people to believe this rather than insisting on explaining the nuances of how to interpret published research. On the other hand, nobody wants to hear a message that things are nuanced, and they will have to do costly hard work to get at the truth.

I think a world where "you can take any published paper at face value...without going direct to primary sources and bouncing it off an expert in the space" would be great, but it never existed, and it's just fundamentally impossible.
