(Updated March 26, 2021) We humans love anecdotes. In fact, here are some fun facts for you:
1) Three out of five people are likely to share an anecdote they found on their social media feed.
2) One on three will find a way to bring it up in a future conversation.
3) Only 13 of 27 take the time to verify whether the incredible fact they just read was in fact too good to be true.
Oh, and in case you haven’t already figured it out, these are just dummy stats that I made up on the fly.

Still, it’s not that far-fetched to think that if there’s one thing people love more than getting smarter, it’s looking at more intelligent. More often than not, the easiest way to do this is to drop some random, out of this world, hyper specific scientific fact designed to leave everyone in awe.
Unfortunately, this also means that many so-called “facts” circulate without any fact checking. And as they repeat themselves out of the blue, the line between fact and fiction blurs faster than you can say “fake news!” “
Here are five of the many, many pieces of “science trivia” that don’t quite hold up when real science – or sometimes, even just common sense – kicks in.
Myth # 1: You only use ten percent of your brain.
Made: There are many ways to dispel this long-held myth. Indeed, the neuroscientist Barry beyerstein willing Seven. Conclusion: we use 100% of our brain… and perhaps the easiest way to prove it is from a practical point of view.
Think about it. What exactly are we talking about when we say “ten percent”? Are we talking about a physical region of the brain? If so, then what’s the point in leaving 90 percent unused? From an evolutionary standpoint, it would make absolutely no sense for our brains to be this big. In fact, the brain consumes about a fifth of our body’s energy, although it only accounts for two percent of the human body’s weight. Or do we assume that our neurons stop receiving signals from other neurons when we hit that “ten percent” quota?
Moreover, no existing study or research supports this silly idea. Also, if this is really the case, then any brain injury or head trauma that does not reach that “ten percent” magic zone should not hinder mental performance.
Myth # 2: It takes seven years to digest chewing gum.
Made: Nope. In fact, you’re just going to poop him straight away. Seriously.
It is true that today’s gum uses synthetic polymers. However, things that are less than 2cm in diameter usually exit the digestive system safely. This myth was invented by your parents to prevent your teen from swallowing chewing gum, and for good reason. While this wad of chewed gum does not semi-permanently live in your gut, it can certainly be a choking hazard, both for children and adults.

Myth # 3: Goldfish have a memory duration of three seconds.
Made: Research shows that contrary to popular belief, a goldfish’s memory lasts beyond a few seconds. In fact, an experiment has shown that they are able to remember things for as long as Five months!
If you own some of these shimmering swimmers yourself, you’ve probably noticed how much they tend to come to the glass of their tank when you walk into the room. What they are exhibiting is in fact associative learning. Your pets have come to associate human presence with feeding time, so they will come closer in anticipation of a delicious goldfish larva. The fact that commercially available goldfish food doesn’t even look like anything they would eat in the wild is proof of this.
In other words, it’s time to stop believing a myth that a fifteen-year-old boy managed to refute with a simple experiment.

Myth # 4: The color red makes bulls angry.
Made: Red alert: This is absolutely false. It’s not the red cape (or muleta) worn by a matador who charges his horned enemy in a bullfight. Rather, this is the way the cape moves that enraged the bull. It has been shown that bulls will charge on a moving cape regardless of its color; red happens to be the preferred color for muletas because it helps to hide the blood (whether it is that of the matador or that of the bull) much more easily.
Still not convinced? How about this: just like other types of cattle, bulls are color blind to red (and green).

Myth # 5: Bats are blind.
Made: You’ve probably heard the expression “blind as a bat”, usually to insult someone else’s supposed poor eyesight. The truth, however, is that on the 1,300 known bat species, none of them are completely blind.
In reality, different species of bats have different levels of visual acuity. Some of the very small bats (microbats) tend to have poorly developed eyesight. On the other hand, larger bats (megabats) have much better eyesight; in fact some of them can see three times better than we can. As for echolocation (the ability to determine the position of an object through sound waves and echoes), many bat species use it in tandem with real vision to hunt for food, especially in the dark caves.
Oh, wait. We are pretty sure this we can not see. (Image: ministicks.com)
