Propaganda has proven throughout history that it can be a powerful tool to pull the wool over people’s eyes and have them believe things that are fake, and in some cases, even deadly. Look no further than World War II to see just how devastating it can be.
Someone asked the internet, “What’s something you once believed only to later realize it was propaganda?” and netizens revealed the devious disinformation that had them fooled for years. Dive into this collection of some of the most jaw-dropping examples.

Gaius_Catulus replied:
This is one of my absolute favorite myths because of its origin. So many interesting pieces of counterintelligence work during that era.
Edit: well I went to read more details including the link of the parent comment, and it seems I have myself fallen for the myth that the carrot story was intended primarily for counterintelligence! Apparently it was intended more to get the public to eat more carrots, so it really was more propaganda. Of course they also couldn't really come right and and say they had aircraft interception radar, so they had to come up a plausible-sounding story anyway, but it's very unlikely to fooled many Germans, if at all.

The War on [Substances]

New York opened dozens of prisons in my area. Prison Guard is the most common job in my family.
If 85% go back to prison, it means it doesn’t work.
