No, your teachers probably weren’t trying to pull the wool over your eyes. In some cases, science has advanced. For example, Pluto is no longer a planet. In other cases, your teachers were probably just misinformed. For example, being taught that *insert-name-of-your-country’s-historical-heroes-here* were the good guys in the story. But it’s okay; we’re here to bring you up to date. These are 25 things you were misinformed about in school.
The food pyramid
For a long time it was considered to be the best dietary plan. Now, it has been updated to MyPlate because research has shown we should be consuming roughly equal amount of whole grains, lean meats, vegetables, and fruits.
There are only 5 senses
Besides the traditional ones, there is balance, pain, temperature, proprioception, etc.
Brontosaurus has been debunked
For several years, scientists claimed that the Brontosaurus never existed. Luckily for dino-lovers everywhere, its debunking got debunked. It’s true, Brontosaurus is a dinosaur again! (as of April 2015)
That doing well in school would lead to doing well in life
It’s not what you know, it’s who you know. This is why people join fraternities, sororities, clubs, associations, etc. However, nothing beats daddy’s business friends.
You will only use cursive handwriting in college
You probably won’t even use a pencil.
The tongue has different taste sections
Scientists have now shown that you can taste anything on any part of the tongue.
Cracking your knuckles will lead to arthritis
It’s a lie.
Note: to clarify, this is something of an old wive’s tale.
You need to learn math without a calculator because you won’t have a calculator with you all the time.
Not only will you have a calculator with you all the time, it will be more powerful than the calculators that took humans to the moon.
Columbus discovered the Earth was round
Not only did the Egyptians beat him to it, the Vikings were the first Europeans to discover America. And oh yea, they didn’t murder the natives.
Note: this wasn’t really debunked, but nobody wants to tell a 5th grader that the Native Americans were the good guys. Because that would mean the bad guys won…
Pluto is a planet
Nope, and for those of you who are mad about this, Pluto isn’t the biggest thing that far out, so why should it get the coveted Planet label?
Glass is a slow moving liquid
It’s an amorphous solid. And no, it doesn’t flow over time.
Wait until you see number 6! It may just surprise you.
You can’t start a sentence with “because”
Because reasons and stuff. Seriously though, in spite of what your English teacher told you, superficial grammar rules are not hard a science. They’re a human construct, and human constructs change.
Adults know what they’re talking about
Most adults still have no clue what they are talking about.
Sunlight powers all life on Earth
This was disproven when scientists discovered creatures that live around thermal vents deep under the sea. No sunlight required!
Veins are blue
No, blood is always red. The veins just appear blue. It has to do with the fact that only blue light can penetrate that deep into our body (past the fat layers). Also, arteries aren’t all that visible because they are deeper. If they were more superficial with thinner walls (like veins), and were therefore more visible through the skin, arteries would arguably reflect a similar color.
Electrons orbit the atom like little planets
Nope, just a probability cloud
Dinosaurs are extinct
While a lot of them are, one species survived. Today we call them birds.
Stomach ulcers are caused by stress and diet
The initial cause has actually been proven to be bacteria.
Note: stress and diet can exacerbate the ulcer.
Your country’s heroes were the good guys
No matter where you are from…Russia, USA, UK, Belgium, Greece, China, or any other country, the kings, generals, politicians, and explorers that your country venerates are the villains in the stories of another country.
Carrots are good for your eyes
And so is every other vegetable. The “carrots-are-good-for-your-eyesight” lie was spread by the British during World War II so that the Germans wouldn’t know how the British were shooting down all their planes. Hint: it was radar…not carrots.
You can’t rely on wikipedia for information
Over time, wikipedia has actually come to be a really good way to see the many sides of an argument, provided that you check the sourcing of everything and also the edit history. Many ideological battles play out over wikipedia and can give a lot more depth of understanding to various views that people hold, including the wrong ones.
The appendix is useless
Scientists have shown that when recovering from illnesses, the appendix actually helps the immune system by flooding your body with useful bacteria.
Women can’t make new eggs
According to recent research, it turns out they can.
You can’t produce new brain cells
Once again, you actually can. It’s called neurogenesis.
Dinosaurs had leathery, reptilian skin
Turns out they most likely had feathers, which makes sense considering the whole bird thing we mentioned earlier.
