Bluechromis and Lee: you both make good points. So what is the solution? First off, the news has always focused on the worse things that happened. That's not new. Should we reduce it? Post less photos of the mayhem.
If youngsters today don't care about traditional news, are they getting it differently, and if so aren't they affected by it similarly? After all people think, act and vote based on what they hear regardless of the source. I'm sure plenty of people have taken measures to reduce forest fires. And while w we may not be able to di anything personal regarding many issues, voters are taking positions on both sides of most issues.
I don't have a panacea. There is a reasonable amount of evidence about the effects of overexposure to toxic media measurably harms people's health. There is information about how skewed and distorted the media reports are. It was interesting to me that the BBC was so much less negative. I'll watch that more now. It would be good if such information were more widely known.
It seems the entire way that truth in society is established is changing. It is often now not about how objective facts give evidence for something or disprove something. I am going to try not to get too political about this, but there is a shift now where more people feel the truth is established by the authority of the person or institution saying it. For such people, the ideal of journalism striving to share facts in an unbiased manner may not be highly valued. They may not believe the media should try to be neutral but should promote certain viewpoints.
It may be that journalism has never been perfectly unbiased. But it is a matter of degree, from pure propaganda in a police state to a semi-free press in more democratic countries. Also, historically in a free society, people had the option to consult several different media sources that would not be likely to share the same biases to try to triangulate the truth. Now many media sources are controlled by a small number of huge corporations that are not shy about skewing reporting to their benefit. We need to try to convey to people that regardless of one's views, there is a terrible risk it putting our understanding of truth entirely in the hands of another person or organization because we give away a huge amount of our power that way.
But the world is an immensely complex place, and typically, the truth about what is happening is not a black-or-white thing but is more nuanced and complex. In the vast majority of history, humans have lived in small bands, villages, or communities that were not so complex. This is compounded by the way that reportage focuses on scattered events, not on larger-scale trends that may shed light on many things.
It may be that, daunted by that complexity, some people resort to simplistic explanations. It takes mental effort to evaluate several sources of information to try to make determinations about what explanations are most valid. There is evidence that people that have extreme biases against certain groups engage in what psychologists call "low-effort thinking." It is easier to think, "all the other people are bad, and all my people are good." than to grasp the reality of it, which is always more complex and ambiguous. We need to convince people somehow that, in the end, it is worth trying to seek the truth.
