Here in the modern world, many of us are more aware than ever of how the media can shape our perceptions of reality. While most debate about "perception management" these days is relegated to the arena of political mudslinging, the truth is, there has always been a concerted media effort to shape how we see the world in the form of advertising. And as many national governments learned early on, the same media infrastructure built to sell us products can also be used to sell us on ideas.
If you're looking for a good example of how government initiatives can shape our idea of reality, you need to look no further than the air campaigns of World War II -- because if you're one of the millions of people that think eating carrots can help improve your vision, you've been duped by half-century-old wartime propaganda.
Not the wartime propaganda posters you were expecting?

British (and eventually American) pilots defending the U.K. from Nazi bombers were among the first aviators in history ever to be tasked with night-time combat operations. Less than four decades after the Wright Brothers first took to the sky, Allied pilots were fighting for their lives in pitch darkness over the European theater.
At the time, aviators had to rely on their senses, rather than on the suite of technological gadgets we use for intercepts in modern combat aircraft, but it wasn't long before the advent of onboard Airborne Interception radar (AI) gave the Brits the edge they needed over inbound Nazi bombers. The British also knew that announcing their new technological advantage would put the Nazi's to work on finding ways to counter it, so instead, they chose a very different track.
As Allied fighters started closing with and destroying Nazi bombers in increasing numbers despite the difficult to manage night sky, the English Ministry of Information launched a propaganda campaign aimed at convincing the world that their pilots had impeccable Nazi-hunting night vision thanks to a steady diet of -- you guessed it -- carrots.
Technically speaking, they're not wrong. A serious Vitamin A deficiency could make you go blind.

Like any good misinformation campaign, they needed to find a basis in fact to use as the bedrock for their campaign, and carrots are known to be a good source of Vitamin A. Technically speaking, eating more vitamin A won't do anything for an otherwise healthy person's vision, but not getting enough of it can cause vision problems. Because of this, it was easy for the Brits to twist the story away from eating carrots to avoid a Vitamin A deficiency, and instead toward the idea that eating enough carrots could actually make you see better at night.
The decision to use carrots was also informed by the nation's sugar rations limiting snack options for the U.K. populace. Carrots were a great snack for school kids to munch on and the nation had plenty of them to spare -- so selling the public on the idea that eating more carrots could turn your kid into a hawk-eyed fighter pilot benefited the war effort in ways beyond German perceptions.
It wasn't long before the idea of carrots improving one's night vision simply became carrots improving vision altogether. Soon, no one remembered where they first heard about carrots being so important to eye health and just started accepting it as the truth.
Amazing what a few posters can do.

Even today, mothers and fathers all over the world continue to tell their kids to eat their carrots because they're good for their eyes. This isn't because there's a great deal of Vitamin A deficiencies in the modern world, but rather, because we're still operating off of the familiar wisdom we gleaned from propaganda posters printed while Hitler was touring Paris.
Propaganda, it pays to remember, is little more than advertising paid for by governments, rather than corporations. We all know and accept the idea that advertising works (to the tune of 3 billion in the United States last year alone). Whether we like it or not, it seems that propaganda does too.
