It’s common knowledge that scientific papers are – well sometimes hard to get through. Even as an experienced researcher who might partake in a journal club, you often struggle to completely understand a difficult paper.
In this brief article, we’ll discuss our best tips on what to do when you come across a paper that is too difficult to understand.
Scientific papers are hard to read because they contain:
When reading a scientific paper, you may find unfamiliar terminology and concepts even techniques, which can discourage you from reading further.
One way to tackle this problem is to take a quick break when you start to get frustrated with it.
After you’re ready to open the paper again, take your time to investigate the unfamiliar terms or concepts and write them down. To understand them, you may have to find and read some additional papers, or you may need to open your textbooks to refresh your memory.

Pro-Tip: Look for review papers on these topics. Review papers can be helpful in breaking down new concepts to help give you a better introductory understanding. For unfamiliar techniques, check the list of references and read the cited papers containing the details about the techniques.
A paper can also be hard to read due to the high density of information presented in one article. Unlike a sentence in your textbook, a sentence in a scientific article can have a combination of two or more complicated ideas.
To absorb the content of the paper, it’s not enough to just highlight the important information on the paper—you must take notes.
However, avoid rewriting each sentence used by the author. Use your own words to capture and process the information you read.

Pro-Tip: You can also make a special notebook, dedicated for literature review. This notebook can be useful for future use when you need to prepare your own manuscript and cite relevant papers for the introduction part.
Oftentimes, no matter how much effort and time you put into reading a certain paper, it‘s still hard for you to understand it. The best way to handle this problem is by discussing the paper with your mentor, postdocs, or other graduate students in your lab. They may share their knowledge and helpful insights to help you understand the paper.
