In the realm of education and personal development, certain misconceptions have gained unwarranted popularity. Here, we delve into four of the most persistent learning myths, examine their origins, and highlight why they lack scientific backing.
1. The Myth of Learning Styles (“VARK” Model)
The belief in learning styles posits that individuals learn best when content matches their self-identified preferences—visual, auditory, or kinesthetic (VARK). This idea has dominated educational discussions, with many educators encouraged to tailor teaching methods to these styles. However, research conclusively debunks this notion.
Key Evidence Against Learning Styles:
- A consensus among scholars (Kirschner, 2017; Pashler, 2008) shows no scientific support for the “matching hypothesis.”
- Dr. Robert Bjork of UCLA explains that the concept not only lacks merit but can hinder effective learning by promoting a fixed mindset.
- A TED talk by Dr. Tesia Marshik (University of Wisconsin-La Crosse) highlights how belief in this myth persists despite contradicting evidence.
Why It’s Problematic:
- Teachers waste valuable time and resources tailoring lessons to non-existent styles.
- Students may develop a false sense of limitation, believing they can only learn in specific ways.
Clarification on Multiple Intelligences: Howard Gardner’s theory of multiple intelligences is often misused to support learning styles. However, Gardner himself has stated that his theory is not about matching teaching methods to purported learning preferences.
2. The Left-Brain vs. Right-Brain Myth
The myth claims that people are either “left-brained” (logical, analytical) or “right-brained” (creative, emotional). This oversimplified view has permeated education, workplace training, and popular culture, but it’s scientifically inaccurate.
Debunking the Myth:
- A study titled “An Evaluation of the Left-Brain vs. Right-Brain Hypothesis” found no evidence supporting the dominance of one hemisphere over the other in shaping personality or abilities.
- Neuroscience confirms that both hemispheres are highly interconnected, working in tandem for nearly all cognitive tasks.
Implications of the Myth:
- Promotes stereotypical thinking about abilities.
- Undermines the understanding of how creativity and logic often coexist in problem-solving.

- TED-Ed lesson by Elizabeth Waters, which explains why this myth persists and why it’s incorrect.
3. The 10% Brain Usage Myth
The idea that humans only use 10% of their brains has been a staple of popular culture and self-help books. Movies like Lucy perpetuate this myth, suggesting untapped potential if we could “unlock” the other 90%. Yet, this claim is unfounded.
Scientific Reality:
- Brain imaging technologies, such as fMRI, show that all parts of the brain have some level of activity, even during rest.
- Neurologist Barry Gordon (Johns Hopkins) dismisses the myth as “laughable.”
- John Henley (Mayo Clinic) asserts that over a 24-hour period, nearly all brain regions are active.
Origins of the Myth:
- Misinterpretations of William James’s writings.
- Misquotes attributed to Einstein.
- Misuse by the self-help industry.
Why It Matters: Belief in this myth can lead to misguided efforts to “unlock potential” rather than focusing on practical cognitive development techniques.

- SciShow’s video featuring Hank Green debunking the myth.
- Scientific American article: “Do People Use Only 10 Percent of Their Brains?”
4. The Learning Pyramid Myth
The Learning Pyramid suggests specific retention rates for different learning activities, such as:
- 10% of what we read.
- 20% of what we hear.
- 90% of what we do.
While visually appealing, this model lacks empirical support and has been widely criticized by researchers.
The Origin Story:
- In 1946, Edgar Dale proposed a “Cone of Experience” without percentages.
- Later iterations added arbitrary figures, often attributed to the “National Training Laboratories,” which admits it cannot substantiate the claims.
Problems with the Model:
- Retention is not linear or easily categorized.
- Actual research on memory and learning does not support these fixed percentages.
Critiques and Clarifications:
- Dr. Lieb Liebenberg and Pedro de Bruyckere have highlighted the inconsistencies and lack of scientific foundation.
- Learning is complex and influenced by various factors, including prior knowledge, engagement, and context.

Conclusion
Understanding and challenging these myths is essential for effective learning and teaching. While such misconceptions can seem harmless, they often divert resources and attention from evidence-based practices. By focusing on what research truly supports, educators and learners can foster environments that promote meaningful and impactful learning.
