Does being left-handed mean anything? (2023)

Why is it rare to be left-handed?

In fact, one of the more unusual hypotheses to explain the rarity of left-handedness is that a genetic mutation in our distant past caused the language centres of the human brain to shift to the left hemisphere, effectively causing right-handedness to dominate, Alasdair Wilkins explains for io9 back in 2011.

Other studies have found that non-right-handers experience more negative emotions. Both findings could be due to the fact that non-righties are more likely to have unusual brain lateralization, which could affect the way their brains process fear and anger.

“When we're left-handed, our right brains are usually dominant, and that's where creativity and intuition are centered. So it's often easier for us to be creative than logical.

Research shows left-handed people may have a lower risk of developing ulcers and arthritis. They may also recover more quickly from strokes.

McManus which found that the Netherlands has one of the world's highest prevalences of left-handedness at 13.23 percent.

This revealed that the 10 percent rule does not hold steady across states. In fact, McManus writes, “The highest rates of left-handedness are in the north-east, in Maine, Vermont, Massachusetts, and Connecticut, whereas the lowest rates are in the mid-West, in Wyoming and North Dakota.”

The “American Heritage Dictionary of the English Language” cites the conventional wisdom that the word “southpaw” originated “from the practice in baseball of arranging the diamond with the batter facing east to avoid the afternoon sun.

Why? A lefty's curveball can be a nasty pitch against right-handers, but it can also throw lefties off too. The curve can head straight for the batter then break at the last second, causing the hitter to instinctively back off.

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.

For example, if both parents are right-handed, there is a 1 in 10 chance of having a left-handed child. If the father is left-handed, the odds are 2 in 10.

A 1967 study by Douglas found no evidence to correlate mathematical ability with left-handedness or ambidexterity. The study compared the people who came in the top 15% of a mathematics examination with those of moderate mathematical ability, and found that the two groups' handedness preferences were similar.

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.

You may have heard that left-hand dominance is a sign of a learning disability. Rest assured, in most cases, left-handedness is a normal part of child development. While it is possible for left-handedness to coexist with learning disabilities or other health concerns, this is the exception and not the rule.

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.

Hand preference probably arises as part of the developmental process that differentiates the right and left sides of the body (called right-left asymmetry). More specifically, handedness appears to be related to differences between the right and left halves (hemispheres ) of the brain.

What does the Bible say about left hand?

Truly, I say to you, they have received their reward. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. And your Father who sees in secret will reward you.”

Left-handed athletes have an advantage in sports that involve aiming something towards an opponent, whether that's a baseball or tennis ball, or a contact sport such as boxing.

The question of whether left-handedness could be inherited was answered in 2007 when scientist Clyde Francks announced the isolation of a gene—called LRRTM1—that contributes to left-handedness. Francks' research suggests the gene is inherited on the father's side.

This is most likely because the left and right hemispheres control motor action on the opposite sides of the body. While this relationship is not straightforward, it would appear that, in most cases, handedness and brain lateralisation go hand in hand (pun intended).

Both left-handed pitchers and batters do better in baseball. Since the majority of hitters are right-handed, lefty pitchers are considered valuable. A curveball from a left-hander breaks inside on a righty – a harder pitch to hit.
