Why Was 'Left' Considered Evil? The association of the directional left with evil is likely attributed to the dominance of right-handed people within a population, and consequently the awkwardness of motions made from the left side of the body. Such darkness wasn't always attached to that side, however.
Left-handed people are said to be good at complex reasoning, resulting in a high number of lefty Noble Prize winners, writers, artists, musicians, architects and mathematicians. According to research published in the American Journal of Psychology, lefties appear to be better at divergent thinking.
Handwriting is considered the most challenging daily activity for left-handed children to perform, I can confirm. My baseline orientation (writing on the line) and spatial awareness was a struggle in grade school.
Overall, individuals with ADHD had a 27.3 percent chance of being either left-handed or mixed-handed compared to 18.1 percent in the general population. So the results suggest that the effects are smaller than for the autism spectrum, but generally go in the same direction.
They have an advantage in tennis, baseball and boxing, for example, because righties have a tough time predicting their less familiar moves. Lefties also have their own special day on the calendar.
Babe Ruth. The Babe is probably the most famous left-handed slugger of all-time.
Some children experience them from early stages of literacy education, while others occur at a later stage while reading texts. In comparison to right-handed people, left-handed people are 2.5-3 times more likely to have difficulty in mastering written speech -- in both writing and reading.
Left-handedness occurs in about 8% of the human population. It runs in families and an adoption study suggests a genetic rather than an environmental origin; however, monozygotic twins show substantial discordance.
Why Is It Harder for Lefties to Hit Lefties? Lefty batters have an advantage on right-handed pitchers, but in a lefty-lefty matchup, it's the pitcher that usually has the edge. Why? A lefty's curveball can be a nasty pitch against right-handers, but it can also throw lefties off too.
First Chronicles 12:2 seems to reference bowmen who were ambidextrous. When the Bible refers to left-handed people, it speaks of left-handedness as an advantage, not a weakness. While it is not as honorable as sitting at someone's right hand, sitting at the left hand is still a position of honor.
Sinistrophobia is the fear of things at the left side or left-handed people. Sufferers may avoid using their left hand, touching someone else's left hand, or touching an object which has come into contact with a left hand.
Wright and Hardie (2012) found that left-handers reported higher levels of state anxiety but there was no difference in trait anxiety. They also demonstrated that when Trait Anxiety was controlled for, left-handers still showed a higher level of state anxiety compared to right-handers.
Infield and Catcher
Baseball administrators and coaches almost never give left-handed players a chance to play second base, shortstop, third base or catcher. Left-handers have a clear disadvantage at those positions.
In their analysis of 144 handedness and brain laterality studies—accounting for a total of nearly 1.8 million individuals—University of Oxford psychologists Marietta Papadatou-Pastou, PhD, and Maryanne Martin, PhD, found that males are about 2 percent more likely to be left-handed than females.
A single gene might be passed from parents to children to influence which hand a child favours. If a particular version of this gene is inherited, the child may be more likely to be left-handed, depending on reinforcement and other environmental influences.
The genetic proposal to explain hand preference states that there are two alleles, or two manifestations of a gene at the same genetic location, that are associated with handedness. One of these alleles is a D gene (for dextral, meaning ¿right¿) and the other allele is a C gene (for ¿chance¿).
If two parents are right-handed, their offspring has a 10% chance of being left-handed. However, if one or both parents are left-handed, the chance of their child being left-handed becomes higher at 18 to 22% and 27%, respectively.
Eleven percent of the population is born left-handed, and if they seem different, it's because they are! Learn six tips for raising a left-handed child.
As demonstrated with her regal right-handed wave, our current monarch, Queen Elizabeth, is no southpaw — but plenty of her relatives/ancestors are/were. These include her great-grandmother Queen Victoria, her dad King George VI, her mum the Queen Mum, and her grandson, William.

Left-handedness in and of itself is not a cause for concern, especially if there have been other left-handers in your family. If you feel worried that your child may have a learning disability, however, it is important to talk to your pediatrician right away.
If the mother is left-handed, the odds rise to 3 in 10. And if both parents are left-handed, the child has a 4 in 10 chance of being left-handed. If a classic dominant-recessive model were in play, then left-handed people would only have left handed kids. But they don't even have left-handed kids most of the time!
