Researchers at the Oxford Internet Institute, who said their study was the largest of its kind, said they found no evidence to support “popular ideas that certain groups are more at risk” from the technology.
However, Andrew Przybylski, professor at the institute—part of the University of Oxford—said that the data necessary to establish a causal connection was “absent” without more cooperation from tech companies. If apps do harm mental health, only the companies that build them have the user data that could prove it, he said.
The scope of this study is way too broad. People use the internet for countless different things, and in many ways using the internet is a daily requirement. They need to focus on specific buckets like news, social media, gaming, etc, of which there are mountains of evidence to show they can cause mental health issues
