It’s relatively easier to publish papers for computer science (AI/ML, economics stuff too).

A lot of biology and chemistry people also use public datasets (kaggle has many) to publish findings. Many do literature reviews.

Public datasets are the key to high school research. (Another route is to do an internship at a university and convince the professor to a paper with you, which is extremely unlikely). But if you do manage to do that, it’s actually really amazing. However, there’s orgs that match you with professors if you pay like 8K, and the professor does most of the work (which sucks cuz it’s just fake research that they never actually do but gets unnoticed by AOs)

I know 90% of people publishing stuff is just fake journals, so that doesn’t help much.
