There seems to be a lot of news around about digital devices paired with some age group leading to emotional or mental damage. TVs have been around 70 years. I'm not convinced devices are a relatively damaging factor in mental health development. Would I rather my child be using a phone or drinking lead-laced water or smoking? The evidence for chemical and biological consequences are more clear-cut and those took decades of measurable evidence. Studies, like these, seem more like trying to fit an assumed conclusion by plausibly random selection bias. Are these studies narrowing the field at all?
