Not the submission process, not reviewer #2, not the editor. Writing the abstract of the paper is often a far greater challenge. And there’s one simple reason for that: most people have a hard time figuring out what’s important for the reader. I ‘ll be sharing tips in next posts - stay tuned!

Tip 4: Make it EASY. Avoid “empty” statements or fancy writing (that’s coming from sbd struggling with their fluffy writing habits). A good writer (in general and especially in science) does just one thing: makes sure every reader understands. Accurate, clean/short sentences, specific, **EASY**.

Tip 3: Be “conservative” (it’s the only case where I recommend it 😝). Stick to the big picture, yes, but by presenting the data that you actually have in the paper. Don’t overpromise. *Don’t present potential interpretations as results*. Don’t make a general discussion - be very specific and clear.

Tip 2: Ask yourself what you would like to read in an abstract of a study on an area that you ‘re not familiar with. The point of an abstract is not to show you have a lot of data nor present every new observation you made; it’s rather to help the reader get the major question and the major answer.

3rd: conclusion/impact/implications
1 sentence is often enough; sometimes 2 are necessary. Provide a short, concise conclusion - what is the punchline? Do you have sth *important* to comment on regarding implications? Could be therapeutic implications or a finding that changes a dogma. Be specific.
2nd: the findings
The longest and main part of your abstract. Here you should explain:
i) what you did and how
ii) what you found
An effective abstract doesn’t bombard the reader with details; you can’t describe all your results. Stick to major.
*Must*: use friends from other fields as beta readers
1st: 1-2 (max) sentences - intro
Present the known and its caveat. It can be as brief as 1 sentence (we know x, but y (somehow linked to x) is unknown) or 2 sentences. My view is that abstracts with more than 2 introductory sentences rarely work well. Specific, clear, only the absolutely necessary.

Tip 1: Follow a tight structure
There’s not only one way, but there certainly is a “safe” and always successful recipe. Your abstract consists of 3 parts:
1st: 1-2 (max!) sentences - intro;
2nd: the longest - the findings;
3rd: 1 sentence (2 could work, but often unnecessary) - wrap it up.
