Intelligence is a multifaceted human trait, influenced by a myriad of factors, ranging from genetics and environment to nutrition and education. A recent scientific study from Russia offers an intriguing perspective on the correlation between ear shape and IQ in children. This finding resonates with ancient folk beliefs such as “big ears denote a high-ranking official” and “blessed with good fortune, intelligence, and prosperity.”
Do Bigger Ears Indicate Higher Intelligence?
A research group led by Professor Mustafin from Kazan Federal University (Russia) conducted a large-scale study on children and made a notable observation: children with larger ears tend to have higher IQ scores compared to their peers with smaller ears. The researchers attribute this to enhanced sound reception, information processing, and brain reflexes.

Not only the size but also the asymmetry between the left and right ears seem to play a role in cognitive tendencies. Specifically:
- Children with longer right ears tend to exhibit superior talent and cognitive abilities in mathematics, physics, and natural sciences.
- On the other hand, those with larger left ears lean towards linguistic prowess, literary and artistic sensitivity, and a more humanist mindset.
Ear Size and Hearing Ability: An Undeniable Correlation
Ears are not just gateways for sound reception; they also significantly impact hearing ability, which is pivotal in a child’s learning process and intellectual development. Research suggests that infants with larger ear flaps often possess superior hearing acuity, enabling them to receive auditory information more clearly and swiftly.

This correlation becomes more pronounced as we age. Individuals with larger ear flaps tend to maintain better hearing acuity in their senior years, facilitating continued social engagement and cognitive activities.
Additionally, slight asymmetry between the ears can reflect uneven brain development, influencing one’s propensity for logical or creative thinking.
Scientific Validation of Folk Beliefs
The Vietnamese folk belief, “big ears denote talent,” is not entirely baseless. From a modern perspective, physical attributes like ear shape can indeed provide some insights into cognitive abilities, albeit in specific contexts.
- Genetics
- Education
- Environmental influences
- Nutrition
- Lifestyle and learning habits
If your child doesn’t have the so-called “ideal ear shape,” there’s no need for concern. Providing a positive environment, ensuring proper nutrition, and encouraging mental and physical exercises can foster holistic development, enabling your child to achieve success in their pursuits.
