Brian O Ogbonna Sometimes, it may not be required by the type of research you are doing. For example, book reviews may not need that.

Nice question. Kindly note that you are the one that just called it a symbol of quality. Others called it weakness of the study. However, there is no single published fact with limitation.

There are many Scholars who are not Professional Researcher. When they review your manuscript or comment on the limitation of your report, you will easily notice that they are highly judgemental and possess average understanding of the concept of science.

I think study limitation should be included in every publication as it open doors to other researchers to go deeper in the subject and find solutions or recommendations for these limitations. However, it should not be considered as weaknesses by reviewers or a reason to reject the paper.

Perfectness in research is a myth. Therefore, showing a research limits and limitations are a sign of perfect imperfectness.
