Nowadays, the rate of publishing review articles is increasing at a faster rate. It seems that researchers are leaning towards investing their time on reviewing published articles in their area of specializations than working on new research ideas. I don’t know if it’s because of its simplicity. However, I also see, on the other side, that review articles can also simplify the identification of research gaps. So, what’s your idea in this regard? What are the main benefits of review articles? Is there any situation where a review article has a comparative advantage of the original research articles? Where? And, how?
