We go through life and learn each day, but sometimes we can be factually wrong in what we believe. Research shows that we tend to embrace information that supports our beliefs, even when it's wrong, and scientists call this "confirmation bias." Sifting through what's true and not can be especially hard online; luckily, there are communities that help debunk common misconceptions and myths.
The "Learned Wrong" is a subreddit dedicated exactly to that, with a mission of "Clearing up misconceptions and outdated information you might have been taught across history, science, [intimacy], health, and more."
From serious science stuff like myths about the ozone layer, to more light-hearted ones like our teachers telling us we won't always have a calculator in our pockets or how periods really work, here are the most interesting things people have unlearned thanks to this online community.

The last step is T — tracing the claim to its original source. Let's take the "We use 10% of our brains" claim — what was its origin? The claim was first made in 1907, when the founder of American psychology, William James, suggested in one of his books that the human brain has far more potential than we use. There are claims that Albert Einstein swore he could access more than 10% of his brainpower, but there are no direct quotes from him.
