My favourite is the story that there was mass panic over a radio broadcast of War of the Worlds where everyone thought a real alien invasion was happening. I heard this story as a kid and really thought this was a cruel prank played by the radio station.
In reality, they made it clear at the beginning of the broadcast, and twice during, that it was fictional. Not that many people were listening and most of the people who were, were aware it wasn’t real. A few idiots freaked out and it somehow turned into a story of mass panic. It was propaganda by newspapers to discredit radio.
The idea that eating carrots helps your eyesight came from WW2 Britain. It was an intentionally spread lie to cover up for the fact that they had radar.
I thought it was changing the light colour of the cockpit lights from white to green.
I don’t get how spreading the claim that carrots help your eyes covers up having radar, it feels non sequitur …
It’s the explanation for why the Allies could spot their planes in situations where they would otherwise not be easily visible. If it happens a few times you might write it off as luck, but if it keeps happening over and over you might get suspicious.
With that said, I don’t think they really bought the carrots thing. Both the Allied and Axis powers knew about radar and how it worked. It’s just the Allies figured out how to build and deploy their systems first.
Radar was used to see incoming German planes, even during the night.
I belive Remote viewing is similar.
