I fully agree with your comment. The article in The Economist seems well-supported by credible research, including the 2017 survey by the Royal Society for Public Health, to which you verified their claims on social media's impacts on mental health. Other sources you obtained, such as UC Davis Health, Yale Medicine, and the National Library of Medicine, support this very notion that excessive social media can be the cause of such issues as anxiety, depression, and self-esteem problems. The fact-checking and cross-referencing of credible studies performed show just how the legitimacy of the claim of this article stands upon solid ground for its evidence-based foundation.
