Scientific "Facts" Were Taught In Schools That Later Turned Out To Be Wrong
Are there any scientific 'facts' that are proven wrong but are still taught at school? Not necessarily scientific, but here are 7 facts commonly told in schools that are completely wrong.
When you get older, EVERYBODY writes in cursive. My 4th grade teacher said over and over again, "The most wealthy and intelligent people use cursive. If you want to be successful you must learn how to write in cursive."
That different regions of the tongue are equipped with receptors for different tastes. I distinctly remember being shown taste maps in school.
Before the Columbus' era, everyone thought the Earth was flat. Not true; we've known the Earth was round since Ancient times; Eratosthenes calculated the circumference of the Earth, like, really fucking accurately in the 3rd century B.C.
That you swallow an average of 3 or so spiders In your sleep in your lifetime. It was actually a scientific study to see how fast fake information could spread.
People only use 10% of their brain. Imagine if every neuron in your brain fired at once, your head might literally explode. Our brains are kinda smart, the smell part isn't running when there's nothing to smell, it's in standby mode.
Peeing in a pool causes the water to change color because of something added to the pool
Blood is actually blue, but when we see it, it's red because as soon as it comes into contact with the air, it oxidizes and turns red. (This was shocking when i found it to not be true)
