> When conducting a systematic literature review, researchers usually determine the relevance of primary studies on the basis of the title and abstract. https://link.springer.com/article/10.1007/s10664-008-9075-7

Edit: On top of that, the second study you linked talks about "Altmetric attention scores of the RAs were used to measure the online attention they received". This indicates to me that they studied public interest from the non-academics and not among the academics. Of course, articles submitted to the scientific journal are primarily aimed at the academics in that field. This abstract is an example of how I would bin the article without reading it because it seems to study something I am not interested in. But again, I would not dare comment on its results because I have not read it.
