Are Left-Handed People Smarter?

Left-handedness has long been associated with skill and intelligence, from Aristotle and Mozart to Marie Curie, Bill Gates, and Barack Obama. According to the Indy100, a fresh study has now once more connected a left-hand preference with greater mathematical aptitude, making left-handed people more likely to be geniuses.

So, what does "hand preference" actually mean? It's not just about which hand you write with; it's also about which hand you use the most for a variety of tasks, like waving and catching. You may actually prefer using your left hand if, for instance, you write with your right hand but shake hands, wave, or brush with your left.

IFL Science claims that people who prefer using their left hand typically have a more developed right hemisphere, which is beneficial for processing and comprehending spatial awareness and mental representations of objects.

Additionally, left-handers have a larger corpus callosum, the bundle of nerve cells that connects the two hemispheres of the brain, suggesting that they process information more quickly than right-handers because of their superior connectivity between the two hemispheres.

According to one theory, this is because right-handed people live in a world that is designed for left-handed people, which forces left-handed people to use both hands, increasing the connectivity between the two.

So how does this increase the likelihood that left-handers will be brilliant? IFL Science tested 2,300 individuals of various ages in a series of experiments with varying degrees of mathematical difficulty.

Each participant was required to complete the same questionnaire to determine their preferred hand. The findings revealed that there was no difference between left- and right-handers while performing "basic arithmetic." However, left-handers outperformed the others when it came to tackling challenging problems.

Extreme right-handers, or those who stated on the handedness test that they prefer to use their right hand for all tasks, underperformed in all of the experiments, according to the findings, in comparison to moderate right-handers and left-handers.

In conclusion, left-handers clearly have an advantage when it comes to difficult and complex mathematics. However, the study serves as a reminder that hand preference encompasses more than simply the hand you write with and instead includes the hand you use most frequently for a variety of tasks. Therefore, extreme left-handers and right-handed writers who also prefer using their left hand for other tasks may share a similar brain structure.

That's all for now. Thank you for taking time to read this blog.
