Even on hard, if you understand the terminology, the fake ones are mostly gibberish.

If you don't understand the terminology, any paper is gibberish :) but I agree, I can detect fake ones fairly reliably in biology, but not in e.g. astronomy.

You don't even really need to know the terminology to detect the fakes.

Right, I could pick out all the hard ones for fields I'm comfortable with, but struggled for some of the easy ones in fields I was less familiar with.
