There are many fake journals that you can pay and then they publish your research even it is not worth to be published. So there are many fake citations for some research works. Also there are published papers with a team of authors that they have a pact to put their name in each other's papers even they don't have any idea about the subject of the paper. It means they cite many irrelevant papers to a research. That's sometimes one cannot trust these citations criterias. Ofc there are high quality journals too. But in general could we say a research is high qualified based on its citations number? What's your suggestion to distinguish a good research from a bad research?
