Imagine that one day you're watching CNN and a breaking news story comes on saying that Diane Sawyer, anchor of ABC's World News with Diane Sawyer, has suddenly quit.
In an interview, Sawyer says the reason she quit was because ABC was demanding, via the White House, that she read a story at the beginning of every newscast that says citizens are rioting in the streets of New York and the National Guard must be called in to restore order.
The problem is the streets of New York are quiet.
Every generation of humans who has ever lived thinks they Know Things For Sure, and they make Big Decisions, Life & Death Decisions, based on these Things They Know For Sure.
And then later, when they are part of history, successive generations inevitably laugh at them.
