This is a byproduct of mass/social media exploiting that mechanic in individuals to keep people tuned in. Fear, obligation or guilt gets to 99% of people. Let's talk about Fear.
Everyone I know with anxiety issues is terminally-online or, before the internet, tuned in to the news every waking minute of their day. They are hyper-aware of the dangers of the world and are always in a falsely-heightened state of arousal.
It makes the world feel smaller and more dangerous than it actually is. It sucks that people are dying in Ukraine. But you don't live there, and have probably never even met a native Ukie. We aren't supposed to react to danger on the other side of the planet. But we're exposed to it and more nonetheless while powerless to do anything about it. It's reinforcing helplessness.
No animal can function this way. It would eventually become so skittish and paranoid it will start making mistakes, and run directly into the crocodile pit while trying to escape a yapping poodle.
The ignorant aren't immune to anxiety because they're retarded; they're tending to the lot in life they do have control over and reacting to dangers that directly threaten them.
The worst self-induced anxiety offenders are the ones who seek out other peoples' conflicts to involve themselves in.
