The idea that humans only use 10% of their brain is a common misconception. It has been perpetuated by movies, TV shows, and other forms of media throughout the years. However, this claim is not only false but also misleading. The belief that we only use a small fraction of our brain capacity has no scientific basis.

The misconception has been around for more than a century. William James, an American psychologist, was the first to mention this theory in his book “The Energies of Men” in 1908. The myth then gained popularity in the 1920s with the emergence of self-help books. From there, it grew into popular culture and found a permanent place in the media.

The Brain and its Functions

The brain is one of the most complex organs in the human body and it controls almost everything we do. It is the center of all our thoughts, emotions, and actions. It is responsible for interpreting information from our senses and generating responses to the world. The brain also controls our body’s internal systems such as breathing, blood circulation, and digestion.

The brain is divided into different sections with each section being responsible for different functions. The cerebrum is the largest part of the brain and is responsible for conscious thought, movement, and sensation. The cerebellum is responsible for balance and coordination. The brainstem controls automatic functions such as breathing, blood pressure, and heart rate.

The Myth Debunked

Studies have shown that all areas of the brain are active and used for different purposes. Whether we are running, talking, or simply resting, different areas of the brain are engaged. Even when we sleep, the brain is still active. Brain imaging technology such as MRI and PET scans has allowed us to investigate the brain in unprecedented detail. These imaging techniques have revealed that the brain is always working and that every part of it is in use.

In fact, the idea that we only use 10% of our brain is so far-fetched that it is almost laughable. If we were using only a fraction of our brain capacity, then it is unlikely that we could perform even basic functions such as breathing or walking. Any damage to even a small part of the brain can have serious consequences on our ability to think, move, or perceive the world around us.

The Source of the Myth

While the myth of only using 10% of our brain has been debunked, it is worth exploring how it became popular despite its lack of scientific foundation. The rise of self-help and personal development in the early 20th century was the catalyst for this myth. Self-help books like “The Power of Positive Thinking” and “Think and Grow Rich” promised people the ability to unlock their full potential, and the myth of only using 10% of our brain was one of the ways in which this promise was made.

The idea that we were not using all of our brain capacity offered hope to people that they could become smarter, more creative, or more successful. The myth also appealed to the notion that humans have untapped potential waiting to be discovered. However, the reality is that there is no evidence to support this idea.

The Importance of Understanding the Brain

Understanding the brain is crucial to advancing our knowledge of the human body and tackling diseases that affect it. By studying the brain, scientists can treat and possibly cure illnesses such as Alzheimer’s disease, Parkinson’s disease, and stroke. However, to do this, we need to move past the myth of only using 10% of our brain and understand that every part of the brain is crucial to our physical and mental well-being.

Furthermore, understanding the brain can help us to improve our education system, develop treatments for mental illness and improve our understanding of human consciousness. The brain is a vast and complex organ, and we are only just beginning to scratch the surface of what it is capable of.


In conclusion, the myth that humans only use 10% of their brain has been debunked by scientists using advanced imaging techniques. The brain is a complex organ, and every part of it is active and used for different purposes. It is important to move past this myth and understand the brain for what it is. By doing this, we can tackle diseases such as Alzheimer’s and Parkinson’s disease, improve our education system and develop treatments for mental illness.

  1. I’m glad to see that this persistent myth has finally been debunked. It’s comforting to know that I’m using all my brain power, and not just 10%. Although, if I was only using 10%, maybe that would explain why I sometimes forget where I put my keys!

    1. Thank you for your comment. It’s always great to hear from someone who is interested in learning more about the brain and its capabilities.

  2. Thank you for writing this informative post about the myth that humans only use 10% of their brain. I appreciated how you debunked the myth and explained the importance of understanding the brain for medical advancements, mental health treatments, and education improvement. One improvement that could be made is to include more visual aids, such as infographics or diagrams, to enhance the reader’s understanding of the brain and its functions.

    1. Thank you for your positive feedback and suggestion to improve the article. We will definitely take your suggestion into consideration and work on including more visual aids in our future posts.

  3. This is an informative article explaining the myth that humans only use 10% of their brain. However, it could have been beneficial to include information on how scientists are currently trying to use brain imaging technology to explore the brain even further and how we can continue to use this technology to understand the brain’s complexities and improve mental and physical health. Overall, it is important to understand that the myth of only using 10% of our brain is not accurate and that every part of the brain is crucial to our overall well-being.
