> Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world

This insinuates that the human brain can not cope with overflow of bad news. That's wrong. For instance, I stopped consuming horrible news media for the most part. So I get fewer bad news in. I also don't watch everything on youtube either; rather than watching a video where person xyz lost family members abc in some crash, I watch and study surstromming reaction videos (these are fascinating to me, because of group behaviour and also individual's showing varied results here). I can select what I do and watch; the whole article feels as if someone had a need to publish a paper rather than make an objective observation. Publish or perish days...
