RE: Surviving A Post Truth World
I stopped watching the news a decade ago for the same reasons as you. If something important to me is happening, like the vote on BREXIT, for example, I then go off and educate myself as much as possible before making a decision.
However, even that process is not infallible as, in retrospect, we can see that much of what both sides said was lies. Also, people were strongly making predictions about stuff they couldn't possible predict.
Your Trump example highlights another problem, even when you do try and find alternative information. I know you wrote briefly but it highlights how personal perspective plays apart.
Being from the UK I know that there is a huge anti-Trump feeling here and people have actually marched to show they do not want him here. So, from my perspective, I would think that he's not coming because he finally sees that he's not welcome here. And that's my personal bias.
But critical thinking can never be independent of the thinker so, although even if I could find out all there is to know about something, I'm not necessarily going to come see to the truth. Even if there is such a thing. Things are rarely that clear cut.
Checking the facts assumes that there are some solid facts and in most cases I don't think there are. Not when there's a human element.
And, doesn't quantum science show us that even in the material world there are not hard facts. What is seen is affected by the observer.
