It's so funny, I find that when my phone is on silent I check it more than if it's in front of me and I can see what notifications are popping up (and can dismiss them or open them). This was what a lot of high school students said when I was working with them and we asked them to keep their phones out of sight, it's almost like the FOMO was too much and they felt better keeping them in view. Like Peter, I feel better when I switch notifications off for most of my apps and only have the most necessary ones pop up like phone and text messages.
