There is always a lot of talk going on about left-handedness. Many believe that left-handed individuals are more intellectual than the right-handed. Some studies state that this is a myth and others emphasize that it’s a fact. Only 10% of the world’s total population is left-handed. However, this group of people still find problems while operating certain things that are designed with right-handed people in mind. To resolve this issue, more and more manufacturers are designing products, like kitchen appliances, which can easily be used by lefties. So if you wish to know the answer to the question, “Are left-handed people smarter?” continue reading this blog!
How Are Some People Left-Handed?
It is said that the right or left-handedness of a person is determined well before their birth, while they are in the mother’s womb. Depending on the differences between the right and left hemispheres of the brain, the hand preference of a child is decided. According to several researches, the handedness of an individual depends on several factors, such as heredity, environment, etc.
In left-handed people, the right brain (or the right hemisphere of the brain) is more dominant than the left.
How Were Left-Handed People Treated in Ancient Times?
In the Middle Ages, there was a lot of discrimination between right and left-handed individuals. People with left-handedness were not treated with respect when compared to the righties. Left-hand preference was associated with witchcraft among women.
However, over the centuries, the approach towards lefties has changed, and today, they are usually associated with increased intelligence and better decision-making skills.
How Does the Brain of a Leftie Differ from That of a Rightie?
As discussed earlier, in a leftie, the brain’s right hemisphere is more dominant. But what other changes can we find in the brain of a leftie? Let’s take a look at the brain functions of a leftie.
Scientists state that the corpus callosum of a leftie is larger than that of a rightie. The corpus callosum is the region that connects the left and right hemispheres of the brain. It acts as a conduit that permits the flow of information from the left hemisphere to the right and vice versa. The difference between right and left-handedness is caused by the size of the corpus callosum. However, future studies need to be conducted to understand more differences in the brains of left and right-handed people.
Now that you have an idea about why certain people are born with left-handed traits, let’s take a deeper look at the answer to the question, “Are left-handed people smarter?”
Unique Characteristics of Left-Handed Individuals
People have always associated left-handedness with a higher IQ. But is this true? Come on, let’s discuss the unique characteristics of left-handed people!
Lefties are adept at “divergent thinking,” a process out of which creative ideas are born. Hence, they are considered to be more creative as well as innovative. Some studies claim that lefties have better intuition than righties. Did you know that lefties are also better at daydreaming? This might be another reason for their enhanced creativity (many ideas are born from daydreaming)!
1. Good at Sports
Many sportspersons are lefties, especially in games, like tennis, where one opponent faces the other. For example, take Rafael Nadal, who has won several Grand Slam titles in tennis. You will also find that lots of other sports celebrities are left-handed!
2. Excellent Artists
Michelangelo and Leonardo da Vinci are prime examples of left-handed people who have excelled in art. But we cannot say that all left-handed individuals are good at art!
Did you know that actor, Keanu Reeves, is left-handed? This Canadian actor’s skills know no bounds, and his acting career spans over 4 decades! He has several awards and accolades to his credit. However, in addition to being a leftie, Reeves has excelled in his field because of his dedication, hard work, and perseverance! Let’s look at more skills to find the answer to the query, “Are left-handed people smarter?”
3. Better Verbal Skills
It’s a general notion that cognitive skills are better in lefties. As far as language skills are concerned, the left and right hemispheres of the brain are better coordinated in lefties. So lefties might have better verbal skills when compared to right-handed people. Again, this is true in the opinions of some scientists, and more research is required to prove that this theory is valid.
James Baldwin, who was a great author, was left-handed. He has received several awards and accolades for his novels, essays, and poems.
4. Good at Hearing
Lefties are better off at hearing slow-changing sounds. The left hemisphere of the brain has control over the right hand, and vice versa. The left hemisphere is better at hearing sounds that change quickly, such as consonants. However, the right hemisphere, which controls the left hand, is more adept at hearing intonation and syllables, which are slow-changing.
5. Typing Skills
A majority of words on the QWERTY-layout keyboards are typed using the left hand. This makes lefties faster at typing when compared to righties. Thus, in jobs involving typing skills, left-handed people fare better than their right-handed counterparts.
Do Lefties Possess Better Spatial Ability?
Yes! Lefties possess better spatial ability than righties.
Spatial ability is the art of understanding the sizes, shapes, and movements of objects. It is a skill required to excel in the STEM (Science, Technology, Engineering, and Math) domains. Lefties have better spatial ability than righties because of the enhanced connection between the left and right hemispheres of the brain. Therefore, lefties are able to perform better in the STEM domains. Must Read: Study on Spatial Ability from the National Library of Medicine.
The Bottom Line
There is always a hot debate going on among people regarding the skills of lefties vs. righties. While there has been a lot of research being done about the enhanced skills of lefties in various fields when compared to their right-handed counterparts, we cannot conclude by saying that left-handed people are smarter than their opposites.
Lefties indeed possess certain skills that outsmart righties by considering some celebrities and their exceptional gifts. However, we must have more data while considering the two groups. And, we mustn’t forget the fact that only 10% of the world’s population is comprised of lefties. In addition, there are numerous right-handed people with immense talent in various areas. So more studies have to be conducted in this area concerning lefties vs. righties.
Frequently Asked Questions
1. Are left-handed people naturally smarter than right-handed people?
Not necessarily. Research has not found consistent evidence that left-handed people are naturally more intelligent than right-handed people. Intelligence depends on many factors, including genetics, education, environment, and life experiences.
2. Do left-handed people have a higher IQ?
Some studies have suggested that a small number of highly gifted individuals are left-handed, but overall research shows no significant difference in average IQ between left-handed and right-handed people.
3. Why are some intelligent people left-handed?
Left-handedness is linked to differences in brain organization rather than intelligence itself. Many highly successful and intelligent people happen to be left-handed, but being left-handed does not automatically make someone smarter.
4. Are left-handed people more creative?
Some studies suggest that left-handed individuals may excel in divergent thinking, which is associated with creativity. However, creativity varies widely among individuals regardless of handedness.
5. Which famous people are left-handed?
Many well-known figures have been reported to be left-handed, including Leonardo da Vinci, Marie Curie, Barack Obama, Oprah Winfrey, Bill Gates, and Paul McCartney. Their achievements result from talent, dedication, and opportunity rather than handedness alone.
6. Is being left-handed genetic?
Yes, genetics plays a role, but it is not the only factor. Scientists believe that both genes and environmental influences contribute to whether a person becomes left-handed.
7. How common is left-handedness?
Around 10% of the world's population is left-handed, although the percentage varies slightly by country and population group.
8. Do left-handed people think differently?
Some research suggests that left-handed people may process certain tasks differently because of differences in brain lateralization. However, these differences do not necessarily translate into higher intelligence.
9. Are left-handed people better at math?
Studies have produced mixed results. While some research found that a few mathematically gifted individuals are left-handed, most people perform similarly regardless of handedness.
10. Do left-handed people have better memory?
There is no strong scientific evidence showing that left-handed people consistently have better memory than right-handed people.
11. Can a person's dominant hand affect learning?
Most people learn equally well regardless of whether they are left- or right-handed. Teaching methods, motivation, and learning environment have a much greater influence on academic success.
12. Is it rare to be left-handed?
Left-handedness is less common than right-handedness, but it is a normal variation of human development and should not be considered unusual or abnormal.
13. Are left-handed people more successful?
Success is influenced by education, skills, perseverance, opportunities, and personal choices. There is no evidence that left-handed people are inherently more successful than right-handed people.
14. Can left-handed children become right-handed?
Some children may learn to use their right hand for specific tasks, but forcing a naturally left-handed child to switch hands is generally discouraged because it may interfere with normal motor development.
15. Should parents worry if their child is left-handed?
No. Left-handedness is a natural trait and is not a sign of developmental problems. Most left-handed children grow up healthy and perform just as well academically and socially as their right-handed peers.
16. Is left-handedness linked to any health conditions?
Some studies have explored possible associations between left-handedness and certain neurological or developmental conditions, but these links are generally weak and do not mean that being left-handed causes health problems.
17. Do left-handed people have different personalities?
No scientific evidence suggests that left-handed people share a specific personality type. Personality is shaped by genetics, upbringing, and life experiences rather than handedness.
18. Can you train yourself to become left-handed?
While you can practice using your non-dominant hand for certain tasks, your natural hand preference is largely determined by brain development and is unlikely to change completely.
19. Why do so many myths exist about left-handed people?
Because left-handedness is less common, it has fascinated people for centuries. This has led to myths about intelligence, creativity, luck, and personality, many of which are not supported by scientific evidence.
20. What does science conclude about left-handed people and intelligence?
Current research concludes that there is no clear evidence that left-handed people are smarter than right-handed people. Intelligence is a complex trait influenced by numerous biological and environmental factors, and handedness alone cannot predict a person's intellectual ability.
Therefore, if you ask us, “Are left-handed people smarter?” our answer is “They might be, but a lot more research is essential in the future to conclude.”
