You can also get causation and correlation reversed. Think about it: "The longer a teen uses (per day) smartphone the more he/she is depressed" could also be "The more depressed teens tend to have more smartphone use per day because they are depressed".
- rowanG077 3y agoThis would imply depressed kids get smartphones earlier. Which is a pretty large unexplained leap.

Could also be a proxy for how involved they are with their kids school (the private schools all try to de-emphasize phone use and some exclusive private schools here in the valley ban them altogether).
