Explanation: In WW2, Britain spread word that carrots improved night-time vision, and that its pilots were eating lots of carrots, in order to ‘explain’ why they were intercepting Nazi planes over Britain so reliably at night.

In reality, they’d figured out how to fit radar on their fighter planes, and wanted to keep that a secret for as long as they could. The hope was that Nazis keeping tabs on civilian British news would fall for the ruse, and buy UK plane radar a little more time undetected.

Carrots may prevent nutritional deficiencies that lead to poor night-time vision, but they aren’t going to make your MK1 eyeballs into NODs.

You know, I’ve heard that story a bunch of times, but nobody ever says the conclusion. How long did it work?
I don’t think the Brits ever figured out if it was successful OR unsuccessful. Propaganda can be funny like that. XD
There’s evidence that the nazis at least knew about the claim, but everything I’ve ever found backs you up 100%, there’s no evidence that the nazis ever fell for or or dismissed it. I can’t imagine anyone gave it more than a minute’s thought though, like even back then it was pretty transparently silly.
This lie was repeated for years in American pop culture, so I think then and future generations of Americans fell for it more than the Germans did.
i mean, that tracks lol
