It is sometimes claimed that the author's country is considered for processing the peer review. Generally, the authors of developed countries receive privilege more than developing countries.
It depends on the topic and where the peer experts are available. In developing countries, language and presentation skills often are a challenge, as English is not their native language.
Thank you for answering. Native languages of many developed countries are not English. There are many developing countries in which English language has reached at a standard stage. Research quality should be the main issue that can overcome the limitation of English and presentation. Many journals provide free language editing service.
How can anyone make sure that the author and the reviewer remain secret to each other? A reviewer who is really entrenched in his/ her subfield will know who is writing on which subjects. An author who is familiar with the field of her/ his analysis will be able to assign particular demands of a reviewer to colleagues who would most likely make such claims!
Oh my, I did not know that "nepotism, protectionism. plagiarism ..." may be involved in the process of "peer-review". Obviously, when humans act it can just be all too human, even if everybody believes it's a neutral process. What a surprise to a social scientist!
Double blind. I think it works, if the authors are not indicated and their cited articles are hidden in the references then it is very difficult to identify them.
Regarding the problem of language, consider that a poorly written manuscript is usually rejected simply because the reviewers fail to understand it, so I disagree with the statement " Research quality should be the main issue".
Hallelujah, a strong believer overcomes all obstacles!
In all articles that I have been asked to review no references were hidden. And besides, I don't need references to develop an idea who could be the author - the subject of the article is the best hint for someone who knows her/ his field of study.
The language problem certainly is a serious issue. However, were does "a poorly written manuscript" start when the author's mother tongue is not the language of the article to be reviewed and a native speaker is the reviewer?
