Lightning and Gray Clouds

As the backbone of society, science has played a pivotal role in unraveling the mysteries of the universe. However, throughout history, it has also been plagued by various myths and misconceptions that can hinder your understanding and lead to inaccurate knowledge. It is crucial to debunk these “science myths” to ensure accurate information and enhance your comprehension of the world.

Shedding light on these falsehoods and delving deeper into the intricacies of scientific concepts can pave the way for a more comprehensive and accurate understanding of the world around us. Debunking myths for precise knowledge can be a tricky task. Some of these popular science fallacies, originating from old wives’ tales, need more scientific evidence. Others are simply based on misinterpretation or incomplete information. This blog will debunk the most common science myths that must be set straight.

Top 10 Science Myths Debunked

There are many science myths, but this blog will focus on the top 10 that are widely believed and passed down through generations. The following are the most common science myths that must be debunked:

Myth 1: Humans Only Use 10% of Their Brain

The truth is that humans use 100% of their brains, but not all parts of the brain are active simultaneously. Every aspect of the brain has specific functions, and different tasks require different areas to be involved. The myth likely originated from the fact that you do not fully understand the complexity of human brains.

Neuroscientific research shows that every part of the brain serves a purpose. Brain imaging studies reveal that humans use more than 10% of their brains, even when sleeping. Just like a car uses different components to function optimally, their brains operate similarly. We use other regions throughout the day for various tasks, utilizing their entire brain. This common science misconception highlights the importance of science communication and education to dispel myths and foster a more accurate understanding of their incredible brain.

Myth 2: The Great Wall of China is Visible from Space

Contrary to popular belief, the Great Wall of China, like most man-made structures, is invisible from space. While it is undoubtedly an impressive architectural marvel, it does not possess the magnitude to be seen with the naked eye from such a distance.

From space, astronauts can witness several prominent features of Earth, such as continents, oceans, and large-scale geological formations. However, the notion that the Great Wall of China is visible from space is simply a misconception. It is only visible from specific low Earth orbits with high-resolution imaging technology.

Myth 3: Bats are Blind

Bats are not blind, contrary to popular belief. Scientific evidence shows that bats utilize echolocation, a complex biological process, to navigate and locate prey. Bats create detailed auditory maps of their surroundings by emitting ultrasonic sounds and interpreting the echoes that bounce back.

Echolocation is a remarkable adaptation that bats possess, allowing them to emit sound waves and interpret the echoes to locate objects in their environment. This unique ability enables bats to navigate in the dark and detect and capture their prey with remarkable precision.

Myth 4: Lightning Never Strikes the Same Place Twice

Despite the prevailing belief, lightning can strike the same place multiple times, especially tall buildings or structures. This phenomenon can be explained by the science behind lightning strikes. When atmospheric conditions favor lightning formation, the path of least resistance is sought by the electrical discharge. Tall objects like buildings provide an elevated point that attracts lightning repeatedly, making them more susceptible to strikes. So, it’s not just a matter of chance; it’s a result of the natural electrical forces at play during a thunderstorm.

Myth 5: The Five Senses are the Only Way to Perceive the World

In addition to the well-known senses of sight, hearing, taste, touch, and smell, humans also possess other means of perception beyond these. These lesser-known senses include proprioception, which allows you to sense the position and movement of your body parts, and the vestibular sense, which helps you maintain balance and spatial orientation. These senses play crucial roles in daily life, yet they are often overlooked or underappreciated.

Myth 6: Cracking Your Knuckles Causes Arthritis

No scientific evidence supports the myth that cracking your knuckles causes arthritis. The popping sound that occurs when you crack your knuckles is attributed to the movement of the synovial fluid within the joint. When you pull or bend your finger to crack your knuckles, the joint capsule expands, causing a decrease in pressure within the synovial fluid. This sudden change in pressure leads to the formation of gas bubbles, which then collapse, creating a popping sound.

Myth 7: You Can Balance an Egg on the Equinox

The belief that eggs can only be balanced on end during the equinox is a myth. This misconception originated from the idea that the gravitational forces are aligned during this celestial event. However, in reality, with practice, you can balance an egg any day of the year. The ability to balance an egg relies on the egg and the surface on which it is placed rather than the equinox.

Myth 8: Sugar Causes Hyperactivity in Children

Although it’s a widespread belief that a sugar rush makes children hyperactive, scientific research suggests otherwise. The perceived link between sugar intake and hyperactivity is more psychological than physiological. A study published in the Journal of the American Medical Association found no significant differences in behavior between children who consumed sugar and those who did not.

Additionally, a meta-analysis of 16 studies on this topic, published in Critical Reviews in Food Science and Nutrition, found that sugar does not affect behavior or cognitive performance in children. The misconception may stem from the association of sugar-laden treats and desserts with special events and parties, which are naturally exciting for children.

Myth 9: The Full Moon Affects Human Behavior

This belief has been propagated through folklore and popular culture, asserting that the complete moon phase can result in strange or exceptional behavior in humans and animals. People often attribute erratic behavior, sleep disturbances, and even increased hospital admissions or crime rates to the occurrence of a full moon.

A comprehensive review of over 30 studies in the journal Psychological Bulletin found no consistent association between the phase of the moon and abnormal behavior. Furthermore, a study published in Current Biology, which analyzed sleep patterns during different moon phases, found that while slight variations in sleep duration and latency might occur, these changes were minute and inconsistent. The fascination with lunar effects is probably more related to the human tendency to seek patterns and connections, even where none exist.

Myth 10: Goldfish Have a Three-Second Memory

Contrary to the pervasive myth, goldfish do not have a three-second memory span. This misconception probably arises from observations of goldfish swimming in small bowls, seemingly forgetting their surroundings within moments. However, this could not be further from the truth. Scientific research has consistently demonstrated that goldfish have a memory span exceeding three seconds.

Studies have shown that goldfish can remember training they received up to a year earlier. For instance, a study published in the Journal of Fish Biology revealed that goldfish could be trained to press a lever at specific times for food rewards. Even after a year, the goldfish remembered the training. This research debunks myths and offers intriguing insights into the cognitive abilities of aquatic creatures. It emphasizes the need to treat them with the respect and care they deserve.

Why Debunking Science Myths Matters

Science myths can have far-reaching implications on society and scientific literacy. They can obscure the true nature of scientific concepts, hinder critical thinking, and foster misguided ideas about the natural world. When people believe in myths, they may develop skewed perceptions about science, undermining the importance of scientific literacy.

Accurate information forms the cornerstone of informed decision-making. When myths cloud people’s understanding, it can result in poor decisions that affect individual and societal well-being. From decisions about personal health to opinions on environmental policies, a clear understanding of science is fundamental. Dispelling myths can pave the way for a scientifically literate, informed society capable of making decisions that positively impact the world.

How to Identify and Combat Science Myths

Identifying credible sources is vital to debunking scientific myths. Here’s a guide to discern them effectively:

  • Look for credentials. Qualified authors usually have relevant academic degrees or professional experience.
  • Respected institutions or organizations typically publish second, reliable sources.
  • Experts in the field vet a piece of research through the peer review process before publication.
  • Evaluate the publication date. Science continually evolves, so recent sources often provide the most accurate information.

To verify information and challenge myths, apply critical thinking and the scientific method. Don’t accept information at face value; question it. Use tools such as fact-checking websites to verify information. Practice lateral reading by checking other sources to see if they corroborate the report. Remember, extraordinary claims require extraordinary evidence. Always be skeptical, ask questions, and demand proof. It’s the science way.


Debunking science myths reveals human general misconceptions about their world. These myths underscore the dire need for critical thinking and fact-checking in your everyday life. In an age where misinformation can spread quickly and widely, it is crucial to cultivate a necessary mindset, seeking accuracy over convenience.
