@jesusmargar @tomw It is constantly happening! Science is so full of absolute sh*t papers, that finding the actual science is like looking for a needle in a haystack.
Today, unless you know someone from that very field who can guide you, you will spend weeks if not months going through crap papers trying to figure out what are actual results and what is just made up stuff. Good luck to find anyone if that field has not seen any active research in 30 years.
@attilakinali mmmh that's not my personal experience as a researcher. I agree about the bad papers but Q1 JCR journals hardly ever have any. I am yet to see an auto-generated book or paper in mathematics.
