Everyday Science Myths

Some "facts" survive not because they are true but because they are repeated. You have almost certainly heard that we use ten percent of our brains, that the Great Wall is visible from space, or that the tongue has a strict map of taste zones — and every one of those is wrong. This quiz is a small exercise in unlearning. Each question takes a comfortable, widely believed claim and checks it against what scientists actually find, then explains where the myth came from in the first place. That last part matters: myths usually start with a kernel of something real that gets stretched, mistranslated, or simplified for a headline. Knowing the origin makes the correction stick. Treat it less like a test and more like five quick myth-busts you can use the next time one of these comes up at dinner. You may be surprised how many you have been repeating yourself.
