Research papers containing abstracts that are shorter and consist of more commonly used words accumulate citations more successfully, according to a recent study published in the Journal of Informetrics.
After analyzing more than 200,000 academic papers published between 1999 and 2008, the authors found that abstracts were slightly less likely to be cited than those that were half as long. Keeping it simple also mattered— abstracts that were heavy on familiar words such as “higher,” “increased” and “time” earned a bit more citations than others. Even adding a five-letter word to an abstract reduced citation counts by 0.02%.
I have no idea if I use short words in my abstracts. I will have to look.
