Unimpeachable sources of information. You can’t drag the majority of the herd away from their crack addiction for confirmation bias. People love to weave narratives in their head that suit their state of cognizance. This has been well studied. And the underlying “cognizance” in any Democratic society is a result of the structure controlling what people think as opposed to what they do. Why? Because you can’t control what they do. The goal of those running the country is to get the leadership element of the population to drink the Koolade. Most of the time it doesn’t matter, but when a the leanings of the society become too severe and a tails event intervenes, bad things will happen which result in massive change against the current extreme.
The type and degree of change is reasonably predictable as long as you remain outside the confirmation bias echo chamber. It’s all about possibilities and not restrictions. Conservation of the trend in place eventually results in massive imbalance and pain. Only under pain does meaningful change occur. I like to say that, “ no one ever jumped off os a 100 story building because the were making too much money and they were too happy.”
