We humans spend lots of time studying and analyzing the most essential moments of our history. After all, many of us strive to better understand our past and the world we live in. But knowledge also includes failure. While some people keep their factual mishaps low-key, others loudly declare their silly (and usually false!) opinions, making people smack their foreheads in disbelief.
Whether it's thinking that the Berlin Wall worked or that learning about WWII is bad for your mental health, some people clearly had a hard time with history, and it shows. Enter the subreddit r/FacePalm, self-described as "a gallery of inexplicable stupidity". The moderators ask the members to share screenshots of human idiocy, all for your amusement.
