Earlier quoted context omitted.
There is an obscure topic where I have read basically every single dissertation, study, etc on that topic (or even just articles that mention it). It is very noticeable how much briefer older publications were. It would be impossible to do that today. I guess I could have an LLM just summarise all the papers…
What's the reason for this? Publish-or-perish? Papers have to be more thorough? Extra junk tacked on for the sake of showing lengthier papers?
There are also appendices, which reviewers aren't required to read. If there's something relevant that doesn't fit in the main body and you don't put it in the appendix, reviewers will point it out and ask for it, and it will influence their grades.
In the end, publishing papers these days is about convincing reviewers rather than actually writing a good paper. And you usually have reviewers asking for all sorts of things.
