We just know that we know nothing

12 facts that people often get wrong

No one can claim to know everything, but most people go through life confident about certain things. However, some of these widely held beliefs are not actually correct, despite their popularity. Let’s have a look at some "facts" you might have gotten wrong!

The idea that insects—particularly mosquitoes—are not animals is widespread, but it’s also incorrect. In fact, insects are the most diverse group within the Animal kingdom, with more than a million species described and representing more than half of the animal population of the planet.

The mistake comes from not considering that "fruit" is not only a culinary term but also a botanical one. Botanically, a fruit is the part of a plant that develops from a flower and contains seeds. This makes tomatoes, peppers, cucumbers, eggplants, and many other foods that we call vegetables actually fruits in the scientific sense.

Countries have a political delimitation, while continents are divided according to geographical criteria. The Russian Federation is the largest country on Earth, bordering fourteen other countries and extending across eleven time zones. It spans across a good part of Eastern Europe, but also across the Ural mountains—one of the recognized borders between Europe and Asia—and stretches deep into northern Asia.

While cold weather isn’t harmless, it is not the direct cause of illnesses like the flu, which are caused by viruses. In colder months, people tend to spend more time indoors and often avoid ventilating rooms, creating conditions that make it easier for viruses to spread and cause illness.

Bats might not prefer to be out during bright daylight, but this does not mean that they are blind. In fact, many species have excellent eyesight, though it is adapted to low-light or nighttime conditions. On top of that, bats also use echolocation, which allows them to navigate and hunt with remarkable precision in complete darkness.

The belief that you must wait a full day before reporting someone missing is a myth popularized by movies and TV shows. In reality, the law does not require a waiting period. In fact, law enforcement agencies stress that the first 24 hours are often the most critical, so a missing person should be reported immediately.

Some man-made structures are visible from space without magnification, but despite popular belief, the Great Wall of China is not one of them. While it is quite long, being over 13,000 miles long, it is relatively narrow, and its earthy colors blend in with the surrounding landscape, making it nearly impossible to spot with the naked eye from orbit.

This one is tricky: Mount Everest is the highest mountain on Earth (29,032 feet)… if you measure the distance from sea level to peak. For the actual tallest mountain, the answer might vary depending on how you measure. Measured from base to summit, Mauna Kea in Hawaii is the tallest at 33,474 feet—though much of it is underwater. Mount McKinley (Denali) in Alaska rises about 18,000 feet from its base to the peak, making it the tallest mountain entirely above sea level. And Ecuador’s Mount Chimborazo, while shorter in height, is the farthest point on Earth from the planet’s center due to the equatorial bulge.

The Earth is tilted on an axis, which causes the amount of sunlight each hemisphere receives to change as it orbits the Sun. Because of this tilt, when the Northern Hemisphere is tilted toward the Sun and experiences summer, the Southern Hemisphere is tilted away and experiences winter—and vice versa. This is why the Southern Hemisphere celebrates Christmas during summer.

Standard medical advice is to gently guide a sleepwalker back to bed rather than waking them, but not because waking them is inherently dangerous. People tend to sleepwalk during deep sleep, so waking them up might startle them or cause confusion and disorientation.

Hair color and thickness are determined by genetics, not by shaving. Hair naturally gets thin at the ends, so when you shave it, the hair shaft appears to be thicker and darker because of the blunt cut. But it's just an optical illusion; the natural size of the shaft remains unchanged.

Coffee is a natural diuretic, meaning it can increase trips to the bathroom. However, the water in brewed coffee still contributes to your hydration and offsets its mild diuretic effect. If you consume coffee in moderation—3 to 5 cups a day, depending on your tolerance—you should be alright. However, drinking extra water on the side is never a bad idea.

Blame evolution: 10 reasons why cats are (not) the worst pets

Cats often get a reputation for being difficult, distant, or unreliable pets. People who grew up with dogs sometimes describe them as cold, stubborn, or uninterested in pleasing anyone. This list looks at familiar cat behaviors that can feel frustrating at first, especially to new owners. Seen more closely, these same traits help explain why cats fit comfortably into many homes and why millions of people continue to choose them as companions year after year. Continue reading to discover that your cat truly loves you!

Calling a cat by name and getting no response is a common experience. Unlike dogs, cats rarely come running just because they are called. This can feel dismissive, even rude, to owners who expect a pet to respond on cue.

What’s often overlooked is that cats evolved as mostly solitary hunters. They did not develop social behaviors centered on following leaders or responding to group signals. Studies and everyday observation show that cats can recognize their names and the sound of their owner’s voice, but they decide for themselves whether to react or not. For many people, this independence means fewer demands for constant interaction and a pet that is comfortable spending time on its own.

Many cat owners know the sound: a slow tap, a pause, and then a cup or pen sliding off the edge of a table. Cats often push objects while watching closely, as if waiting for the result.

This behavior is tied to curiosity and learning. Cats use their paws to test how objects move, whether they roll, wobble, or fall. This kind of testing is connected to hunting instincts, where judging motion and distance matters. While it can be annoying, it also shows that cats stay mentally engaged with their environment instead of simply reacting to commands or routines.

Some cats appear deeply committed to a favorite chair, window, or room, while paying less attention to following their owners around the house. This can be mistaken for emotional distance.

In reality, cats rely heavily on familiar spaces. Territorial behavior is well documented in feline behavior, and known areas provide safety and predictability. Many cats show affection by choosing to remain near trusted people within these familiar spots. Staying close without constant contact is often how cats express comfort and attachment. It looks like indifference. It usually isn’t.

Cats can learn routines, such as using a litter box or recognizing feeding times, but they rarely perform tricks or tasks simply to please people. Compared to dogs, they are often labeled "untrainable." Domestication helps explain this difference. Cats were domesticated much later than dogs and retained more independent behavior. Dogs were bred over thousands of years for cooperation with humans, while cats largely adapted themselves to human environments. For many owners, this means living with an animal whose behavior feels consistent and self-directed, rather than shaped by constant training.

Adult cats sleep a lot—often 12 to 16 hours a day. This pattern comes from their natural rhythm as predators that conserve energy between short periods of activity. Instead of constant attention-seeking, cats rest when nothing demands their focus. For many households, this makes cats easier to live with, especially for people who value quiet or spend part of the day away from home.

Cats frequently refuse foods that dogs would eat without hesitation. They are obligate carnivores, meaning their bodies are designed to rely on nutrients found primarily in meat. They require specific amino acids that plant-based foods do not provide. Their selectiveness reflects a digestive system shaped by evolution, not stubbornness. Once owners understand this, feeding routines often become simpler and more predictable.

Every new couch seems to be noticed immediately. Scratching furniture is one of the most common complaints about cats: sofas, chairs, and rugs often suffer. Scratching serves several purposes. It helps cats stretch muscles, maintain claw health, and mark territory using scent glands in their paws. While scratching can damage household items, the behavior itself supports physical comfort and well-being. Providing appropriate scratching surfaces allows cats to meet this need without constant correction.

Some cats nip during play or petting, especially when stimulation becomes too intense. It feels personal, but it rarely is. In many cases, cats show subtle warning signs first, such as tail flicking, ear movement, or muscle tension. Overstimulation, particularly around sensitive areas like the tail or lower back, triggers these reactions. Owners who learn to read these signals often find that cats communicate boundaries clearly and consistently.

Cats are often active early in the morning or late at night, which can interrupt your sleep. This crepuscular pattern comes from hunting instincts, as small prey animals are active at those times. Even indoor cats retain this rhythm. While it doesn’t always align with human sleep schedules, it also means cats can go about life without constant attention during the day, when many households are busiest.

Cats may ignore attention for long periods and then suddenly want closeness. This shift can feel confusing or inconsistent. They usually approach people when they feel calm and secure. Affection offered on their terms often feels different—and more noticeable—than affection given on demand. For many owners, these moments feel meaningful precisely because they happen by the cat’s choice rather than by routine or training.
