12 Things you learned in school that have since been proven wrong

Tongue taste maps

Do you remember dividing a scheme of the tongue into 4 areas: sweet, sour, salty, and bitter with an assumption that the taste buds located in these areas identify specific tastes? You should forget about this myth forever! Actually, there are 5 scientifically-identified basic tastes, and the entire tongue can sense them. The idea of the tongue taste map dates back to 1901 and has been proven wrong multiple times since then.
