I was sitting at a table at a sports club the other day where a young fella had put down his phone. It lit up and I saw a terrifying stack of notifications, 20+ messages per app, more apps than space on the lock screen. If I get one then I read it and it I get too many that I don't read then I stop them because they're clearly about something I'm better off reading at my leisure rather than being alerted.
My iPhone looks like that because you have to manually interact with or swipe to clear notifications to remove them
from the stack. And usually I get all the information I need by looking at the preview.
I recommend turning off most notifications in the settings except the ones you absolutely need for your work and family. iOS has a pretty good level of granularity.
