Well, one factor you have to take in is that the 'News' is served up in a particular way. Firstly, there's overkill on it. Like the internet, it's swings and roundabouts. One the one hand, you may not be shocked at stuff that might go on in your personal experience - due to knowledge of events on the news. But the sheer scale of the amount of news is beyond anything the normal human brain can assimilate, so you are simply not being fair on yourself by exposing yourself to all this, it isn't normal.
I mean, in the 15th century, what 'news' would you get? You'd be stuck in a village all your life and never go further afield. Okay, so you would die in your 40s if you even got that far, and of Black Death but... Ditto for many actually even 100 years ago, not that much news, and without TV it would be on the basis of making the effort to read a paper.
The other thing is, the 24 rolling news cycle tries to make it like the hit parade of decades ago, with a big kerfuffle and 'straight in at no 8 this week' or 'now for some breaking news' - it aims to raise your dopamine levels and stress levels too.
Finally one common denominator of all this news is that mostly you and I can do very little about any of it, we have no sense of agency - so of course the overall feeling is that of despair and being out of control, hardly a nice way to think. It breeds anxiety, almost like those Times supplements that bang on each and very week about health tips and stuff, it's too much, also book reviews where you feel you ought to read the suggestions but never get to it.
I know if I didn't watch the News it wouldn't make any difference to the outcome of events, but I don't feel that, it's like the fan watching a football match, he kids himself his tension affects the result. It also really is a form of entertainment but not a healthy one.
For some reason I can't get on X/Twitter on my computer of late and feel happier for it - but does that mean I am being selfish and blind for not keeping in with it?
