I'd love to see a study comparing the attention spans, anxiety level, and overall mental health of that 37% relative to the other 63%. They might be slightly less informed, but I'd bet significantly healthier (mentally).
This would be a terrible study to try to ascertain the impact of the internet on mental health. You would be comparing two populations who are completely different in many many ways.
I know poor people getting into 200% APR loans because of not getting a job during COVID and no math knowledge for refinancing smartly. If you think the bottom 50% is not anxious all the time, you are lucky to live in the 1st world.
The vast majority would of the people in that place would laugh at western problems and mental illnesses. I'm from similar background, trust me.,it comes off as extremely elitist.
