You mean like how Big Oil, Big Auto, etc, and the mainstream media teamed up to deny climate science for over a half a century, bringing the health of the planet and its inhabitants to an existential cliff (or off the cliff)?
Everybody claims they've "got the science and the facts" nowadays (the more convincing ones even have slick graphs and charts). Most everybody on the interwebs and mainstream media (including this forum) believe they see the world wholly and see it clear. The problem today with social media is that the message is no longer tightly controlled/spun by 5-6 entities, as in the past--that's why it feels like we live in a "post truth" world now. It's confusing/frustrating/maddening for anyone who thinks about it for a second: we each have to find our own truth now, and there's a million different truths and 50 sides to the same coin, and it's this huge war between Big Money, Special Interests, and us little people (most of whom have the functional literacy of a 7-yr-old).
Like Charlie Munger (Buffett's right-hand man) says: "Show me the money, and I'll show you the outcome." There's lots of money out there swirling around trying to convince us, manipulate us, prod us, scare us, etc.
It's awfully hard these days to figure out what the "truth" is, if there is any. My whole life I've been told climate change is a hoax, but I'm still fairly certain it's the biggest threat facing humanity right now; it's why I'm invested in TSLA.
But maybe I'm wrong...
