I sat this morning and was reading through the British paper....the Telegraph. It had an interesting piece on a medical study about PTSD in kids.
So, kids that sit and watch BBC and Sky News in Britain appear to have some chances of getting post-traumatic stress disorder.
All of this goes to the various clips that you see nightly.....even in the US (CNN, Fox News, ABC, CBS, MSNBC, NBC, PBS, etc). Most of us don't think about this. You see some bombed-out neighborhood in Syria, or some apartment complex burning away....but in the eyes of some kid, it's a pretty dramatic moment.
Resolving this? Well....how? You could go and make the network news folks only carry the dramatic stuff after 9PM. They (the journalists) would laugh at you and suggest that it will be a fairly undramatic news period from sun-up to 9PM (they are correct). You could forbid any images or video of dramatic news pieces (that would also make the whole news show concept pretty boring).
If you go and review nightly news coverage from the early 1980s.....there's rarely anything graphic or upsetting with what people typically saw. All of this graphic stuff....the kind of material to trigger PTSD....started in the past twenty years.
What happens now? Mostly nothing. No one wants to change the magic formula.
