I personally feel like most of the problem is exploitation.
When the news has some piece, "New research blah blah blah," you and I and most of our peers know that "new research" is unlikely to stand up to the test of time. Yet it's breathlessly reported by one station, and derided as nonsense on another station.
When the weather report predicts no rain, and it rains, you and I and most of our peers know that the prediction wasn't wrong, that we're just talking about likelihoods.
When polls predicted a 99% chance of Hillary Clinton winning, you and I and most of our peers know that the polls weren't wrong. Sometimes chance comes out that way. Plus, reporting those polls probably impacted the outcome.
The news, and politicians, and talking heads, want our outrage because that's engaging. So they exploit us, by misrepresenting research, science, polls...
Which erodes trust in authorities.
And yes, sometimes authorities did horrific things. Like the Tuskegee Experiment. Or silencing Li Wenliang. Or MK-Ultra. Gulf of Tonkin. Red Flags.
