Much of what we "know" about the world isn't knowledge at all, just ideas repeated so often they become unexamined truths. From biology to technology, ancient diseases to modern innovations, our brains latch onto explanations that are simple, visual, or emotionally satisfying, even when the facts say otherwise. But by examining how one false belief leads into the next, we find a strange kind of map: not just of misinformation, but of the way human intuition can lead us astray.

Myths of Nature

Let’s start with one of the oldest and most widely believed myths: that camels store water in their humps. Contrary to popular belief, camels don’t carry water in their humps. they store fat. This fat acts as a reserve energy source, not a hydration tank. When metabolized, fat releases water as a byproduct, but it’s the camel’s oval-shaped red blood cellsthat truly help it survive dehydration by flowing more efficiently under stress.

This misunderstanding, mirrors how we mistake biological mechanisms in other organisms.Take carnivorous plants, for instance. People often believe they must consume insects to survive, when in reality, they don’t. While carnivorous plants like Venus flytraps do consume insects, they do so not to stay alive but to enhance growth in nutrient-poor environments. These plants are perfectly capable of surviving without eating animals, just like camels survive without water. In both cases, we assume that what a creature appears to consume must be its lifeline.

This same mistaken dependency appears in another popular ecological myth: that European honey bees are essential for human survival. The claim that humanity would perish without honey bees is emotionally powerful, but biologically false. While honey bees are indeed important pollinators, the major global staple crops, including wheat, rice, maize, sorghum, and soybeans—are wind-pollinated or self-fertilizing. Only about 30% of global food production depends on insect pollination. Much like with carnivorous plants and camels, we’ve overestimated a single input’s importance and underestimated the complexity of natural systems.

Next up are white ants. Despite their nickname, “white ants,” termites are not ants at all. Genetic analysis shows termites are highly evolved cockroaches, not members of the ant or bee family (Hymenoptera). The similarity in behavior; colonies, castes and queens, is a case of convergent evolution, not shared ancestry.

Myths of Well-Being

This confusion continues with diseases like leprosy, which many still think causes body parts to rot and fall off.

Leprosy, or Hansen’s disease, does not cause limbs to fall off. Instead, it causes nerve damage and inflammation, which, when left untreated, can lead to secondary injuries and disfigurement. The disease is also only mildly contagious, with 95% of people exposed to the bacterium never developing symptoms. The idea of visible, dramatic decay has overshadowed the less sensational, but far more accurate biological facts.

What people think is leprosy is actually a different condition recorded in the bible, often identified as "tzaraath" (also spelled tzaraat or ṣāraʿat in Hebrew).

A similar gap between popular perception and medical complexity exists with tuberculosis, which many think only affects the lungs. While tuberculosis (TB) is best known for affecting the respiratory system, it can also infect the spine, kidneys, lymph nodes, and central nervous system. This is known as extrapulmonary TB, and it complicates diagnosis because the symptoms vary widely. Both TB and leprosy show how our understanding of disease is often stuck in outdated imagery, rather than current science.

Sometimes, our misunderstandings of biology extend to the very fluids inside us. For instance, there’s a persistent belief that urine is sterile. Modern research using genetic sequencing techniques has shown that urine is not sterile. It contains low levels of bacteria even in healthy individuals. The misconception likely comes from standard urine tests, where low bacterial counts return “negative” results—suggesting complete sterility, when in fact the bacteria are just below detection thresholds.

Like many myths, this next one arises from a misinterpretation of medical testing, a trend we see again in the dangerous belief that someone having a seizure can swallow their tongue. It is anatomically impossible to swallow your tongue during a seizure. Yet this myth persists, often causing bystanders to force objects into a person’s mouth, risking choking, broken teeth, or injury. The correct first aid response is simple: gently roll the person onto their side, remove nearby hazards, and let the seizure pass.

Myths of Technology

The tendency to act quickly, even wrongly, and out of panic, also fuels the modern tech myth that putting a wet phone in rice will fix it. Although popular, rice has never been proven to dry out phones effectively. In fact, it's no better than air-drying, and can leave residue or starch particles inside your device. Silica gel or other desiccants are far more effective.

Speaking of gels, powders, and other mixtures; the phrase “ashes to ashes” evokes a powerful image of the body returning to dust; a poetic closure often invoked at funerals. But when it comes to modern cremation, that comforting phrase is misleading.

Modern cremation takes place in a specialized chamber called a retort, which reaches temperatures of around 1400 to 1800°F (760 to 980°C). Soft tissues such as skin, fat, and internal organs, are rapidly incinerated by the extreme heat and reduced to gases and vapor. These components completely combust, leaving no residue. What’s left behind after cremation are bone fragments, not ashes in the traditional sense. These bone fragments are then collected from the retort and placed into a machine called a cremulator, which grinds the fragments into a fine, sand-like powder that resembles gray or white ash. So when you receive an urn with "ashes," what you're really receiving is ground bone.

Just as we oversimplify modern technology, we often oversimplify historical technology, assigning inventions to single individuals when the truth is far more collaborative.

Despite common belief, Thomas Edison did not invent the light bulb, nor did Henry Ford invent the automobile or the assembly line. Edison improved the bulb and made it commercially viable; Joseph Swan was the one who built a working version first. Ford optimized mass production, but Karl Benz, founder of Mercedes Benz, built the first modern automobile.

Conclusion

From camels’ humps to cremation remains, from bee pollination to bladder bacteria, the myths we carry often share one trait: they’re visual, dramatic, narratively satisfying.

By tracing how one misunderstanding leads to another, we begin to see a deeper pattern, not just in the myths themselves, but in the way we construct reality.

And once we begin replacing these myths with facts, we don’t lose wonder—we gain a better understanding of just how strange, complex, and surprising life can be.
