Lefties historically have had a tendency to get left behind. Until relatively recently, being left-handed was stigmatized , sometimes as an abnormality or sign of weakness. Left-handed children were forced to learn to write with their right hands, often to their significant disadvantage. For one thing, lefties have comprised roughly 10 percent to 15 percent of the general population for many thousands of years. The fact that the trait has remained stable over many generations suggests that left-handedness is not an evolutionary weakness, as many psychologists of the past believed. But handedness does come with certain physiological and neurological differences. Research remains incomplete, but here are some things we know about the unique cognitive and psychological profiles of the left-handed:.
10 Things Lefties Do Better
One really interesting factoid that I picked up was from a scientist who believed that left handed people tended to be more independent as a result of having to adapt to a world which is largely built for right handed individuals.

Since prehistoric times, left-handed individuals have been ubiquitous in human populations, exhibiting geographical frequency variations. Evolutionary explanations have been proposed for the persistence of the handedness polymorphism. Left-handedness could be favoured by negative frequency-dependent selection. Data have suggested that left-handedness, as the rare hand preference, could represent an important strategic advantage in fighting interactions.
However, the fact that left-handedness occurs at a low frequency indicates that some evolutionary costs could be associated with left-handedness. Overall, the evolutionary dynamics of this polymorphism are not fully understood. Here, we review the abundant literature available regarding the possible mechanisms and consequences of left-handedness.

Lefties make up about 10 percent of the general population. But researchers have found that in populations with certain mental disorders, that rate goes up. Previous studies have found that people with psychosis had a 20 percent likelihood of being left-handed, though a small study in the journal SAGE found the rate of psychotic lefties may be even higher.
For those with mood disorders such as depression or bipolar disorder , the rate of left-handedness was close to average, at 11 percent.

The internment of a ship at Sutton Hoo represents the most impressive medieval grave to be discovered in Europe. But who was buried there and what did it reveal about this period in history?

This paper is about a little studied aspect of Humanity and one of the last unorganized minorities in society. It x-rayed handedness and its types. The frequency of left-handedness is greater in Euro-American than in oriental cultures and restrictions on using left hand are ingrained in the belief system and social interpretation in a given culture. The descriptive research approach was used to unravel what the Bible and the Quran say about Left-Handedness.
The right hand is mentioned positively times in the Bible, while the left hand is mentioned only 25 times, all negatively. The dominant hand is always stronger than the other arm, and 90 per cent of people are right handed. By implication, in the vast majority of people, the right hand is stronger. Thus, the Bible uses the right hand as a symbol of strength and honor and stated that in the left hand are riches and honor.

D r Michael Proulx, from the department of psychology at the University of Bath, said: “This study is unique in giving us a look into a private behaviour in a private culture with implications for all people. It turns out, we as humans are similar even if our social values differ. This is specific to the functions in the left cerebral hemisphere, located in the emotion and decision related areas of the brain.
Hormone levels, such as testosterone, might be unevenly distributed in each hemisphere, causing a bias to turn right. It is hoped the findings will feed into further studies of neurophysiological mechanisms of such behaviours.

One possible reason for the link between lefties and huge wealth? A study published in the Journal of Experimental and Clinical Neuropsychology JECN found that lefties possess key traits related leadership — including inhibitory control and working memory operations — which may make them better suited for business. You may have heard that left-handed people are more creative than right-handed ones, and there may be a grain of truth to the old adage.

Lefties seem to have some protection against ulcers and arthritis, according to a surprising study published in the journal Laterality: Asymmetries of Body, Brain and Cognition.
Study Reveals Why Lefties Are Rare
A person who is left-handed primarily uses his or her left hand, more so than the right hand; a left-hander will probably use the left hand for tasks such as personal care, cooking, and so on. Writing is not as precise an indicator of handedness as it might seem, because many left-handed people write with their right hand but use their left hand for other tasks.
Left-handedness, in comparison to the general population, also appears to occur more frequently in identical twins, and several groups of neurologically disordered individuals people suffering from epilepsy, Down’s Syndrome, autism, mental retardation, dyslexia, etc.
Research shows that men are more likely to be left-handed than women. Female left-handers seemed to be rarer than male left-handers.
But, the truth is, dominant-hand bliss is actually total BS for most left-handed people. The same goes for lovers. Give me a more intriguing, challenging object of curiousity any day over over an easy-to-operate system or device… therefore, dear universe, please gift me with a beautiful lefty to love.

Righties might have a more dominant left hemisphere, but lefties tend to have more symmetrical brains, processing information in both hemispheres.
But given all the years any given lefty spends struggling to adjust to the right-handed world, our left hemispheres are pretty kickass too.
