Reactions to textual content posted in an online social network show\ndifferent dynamics depending on the linguistic style and readability of the\nsubmitted content. Do similar dynamics exist for responses to scientific\narticles? Our intuition, supported by previous research, suggests that the\nsuccess of a scientific article depends on its content, rather than on its\nlinguistic style. In this article, we examine a corpus of scientific abstracts\nand three forms of associated reactions: article downloads, citations, and\nbookmarks. Through a class-based psycholinguistic analysis and readability\nindices tests, we show that certain stylistic and readability features of\nabstracts clearly concur in determining the success and viral capability of a\nscientific article.\n
