This is not a scientific report of a study, but a popular piece based on multiple studies. In an academic article every material claim has to be supported by data or previous literature. The claims have to be well specified and the study must be (or at least should be) explained in enough detail that reader can understand more or less exactly what was actually done. This tends to make very annoying reading, but also makes it clear that the results very rarely are as straightforward, generalizable and strong as presented in a popular article.

The main study report linked in the article seems to be so well paywalled that it is not available via my university's library nor sci-hub.

Also scientific studies tend to be heavy on jargon, and if they weren’t they would be significantly longer reads, and become extremely tedious for someone who is steeped in the discipline and therefore has the most reason to read the study.
