15 Things That Should Be Common Knowledge Once And For All


While it’s impossible for one person to know absolutely everything, there are certain bits of information we should all have a basic understanding of. It’s called common knowledge and it’s defined as something that’s known by most people. There are quite a few things that should be common knowledge, but they aren’t. Have you been in awkward situations when you assume everyone around you should know a certain fact because you think it’s common knowledge? Then you try to crack a joke and everyone’s looking at you dumbfounded. Here are some examples from Diply that should become common knowledge once and for all.

Don’t feel bad if you were unaware of these facts! Everyone learns something new every day.

1. Rosa Parks wasn’t the first to refuse to give up her seat.

Claudette Colvin was just 15 years old when she refused to give up her seat on the bus to a white passenger. This happened nine months before Rosa did the same. Colvin said, “It felt like Sojourner Truth was on one side pushing me down, and Harriet Tubman was on the other side of me pushing me down. I couldn’t get up.”

2. Bowls are a terrible place to keep a goldfish.

One experienced fish owner says: “Goldfish bowls are the equivalent to putting your goldfish in the toilet and expecting him to show you his best colors, grow to the size of a softball, and never get sick — it just isn’t going to happen.” Makes me sad!


3. Your rear view mirror has a night mode.

If you’re driving when it’s dark outside and want to get rid of the glare from other vehicle’s headlights, there is a simple solution. You can push the tab on your rear-view mirror to activate it.

4. One large pizza is better than two mediums.

It’s not going to save you a lot of money when you buy two small ones! That’s why it’s best to go big on this one. It’s simple math, as the circle increases with the square of a radius.

5. Frankenstein is the name of the doctor.

Okay, this should be obvious to the book/movie lovers out there! While most people think the dude pictured below is Frankenstein, he’s actually just known as “The Monster.” The creator is Dr. Victor Frankenstein.

6. Most cats are lactose intolerant.

Cats and milk don’t actually go hand in hand. Even though they love it, a cat’s digestive system is not built to handle standard cow’s milk.


7. You can use your earbud headphones as a mic.

You can plug them into the mic jack of your computer or recording device.


8. You don’t need a rooster to make eggs.

Revelation? I was explaining this to a woman and she asked how chickens produce their eggs if there isn’t a rooster around. To which I replied, “You produce an egg every month, is there always a man around?” That made it click.


9. The phrase is supposed to be “for all intents and purposes.”

Not “for all intensive purposes”. Also, “could’ve” is not the contraction of “could of,” but of “could have,” okay?


10. A pony is not a baby horse.

Baby horses are called foals. Ponies are a small breed of horses. Both are cute, though! But not the same!


11. Our bodies tend to follow the Rule of Three.

The average person can go three minutes without air, three hours without shelter in extreme weather environments, three days without water, and three weeks without food.

12. You should chew aspirin if you’re having a heart attack.

Researchers in Texas found chewing aspirin instead of swallowing it reduced TxB2 concentrations by 50% in five minutes compared to twelve minutes. Amazing info!

13. “Organic” and “gluten-free” labels do not always equal healthy.

Organic sugar is still sugar and gluten-free fast food is still fast food. You need a bit of common sense for this! Fresh is always the best!
