males
One biological effect on hand preference is known to be sex, with males more likely to be left-handed than females2,14. For example, in a U.S. dataset aged 10–86 years, the proportion of non-right-handers among 664,114 women was 9.9%, versus 12.6% among 513,393 men2.What exactly is this new theory Researchers say the steadily low percentage of lefties "is a result of the balance between cooperation and competition in human evolution." Humans have long had an evolutionary need to cooperate, such as when sharing tools or hunting in groups.Early right-handers had advanced language skills compared to late left-handers; however, early right-handers did not differ from late right-handers. Late right-handers and late left-handers were also not different on language level. Finally, cognitive and motor ability did not vary by handedness trajectory.
Are left-handed kids different : A 2022 Psychology Today article reported an excess of gifted children among individuals who are left-handed, higher scores on verbal-reasoning tests being one indication. It has been found that left-handers often exhibit good skills in communicating through language, and many of them are very creative people.
Who has higher IQ left or right-handed
Right-handers have negligibly higher IQ scores than left-handers: Systematic review and meta-analyses. Papadatou-Pastou M, et al. (2015). Intelligence and handedness: Meta-analyses of studies on intellectually disabled, typically developing, and gifted individuals.
Why am I left-handed : It was initially thought that a single gene controlled handedness. However, more recent studies suggest that multiple genes, perhaps up to 40, contribute to this trait. Each of these genes likely has a weak effect by itself, but together they play a significant role in establishing hand preference.
Research suggests that between ten and twelve percent of the world's population is left-handed. Even though being left-handed might mean struggling with right-handed scissors from time-to-time, there are plenty of reasons being a lefty is pretty cool!

Lefties make up only about 10 percent of the population, but studies find that individuals who are left-handed score higher when it comes to creativity, imagination, daydreaming and intuition. They're also better at rhythm and visualization.
Are left-handed kids gifted
The authors compared the handedness of children in the normal IQ range (85-115) to that of the children in the gifted (greater than 130) and highly gifted (greater than 140) categories. There were no significant differences in the percentages of left- and right-handers in any of these groups.We also find robust evidence that left-handed (and mixed-handed) children perform significantly worse in nearly all measures of development than right-handed children, with the relative disadvantage being larger for boys than girls.Special or not, lefties are born, not made: Genetics are at least partially responsible for handedness. Up until last year, it was assumed that hand preference comes from asymmetrical genes in the brain—two hands, two brain hemispheres, one is dominant.
Although data suggested that right-handed people had slightly higher IQ scores compared to left-handers, the scientists noted that intelligence differences between right and left-handed people were negligible overall.
Is left-handed ADHD : 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.
Is it good to be left-handed : Some research has suggested that left-handers have unique qualities over their right-handed counterparts. For example, they are believed to be more creative and more athletic and to have better memories.
Are lefties different
The article reported findings in MRT imaging indicating left-handed people differ from their right-handed peers in three main areas of the brain, including the motor cortex for both sexes and the striatum and the white matter of the cerebellum in male participants.
In Western countries, lefties make up only about 10% of the population. Folks who favor different hands for different tasks (mixed handed) or who use both hands with equal skill (ambidextrous) are uncommon.8: Solve Math Problems
Given the lefty tendency toward excellence in divergent thinking, it's not terribly surprising that they also tend to do well in math. This has long been the line of thinking, and a 2017 study published in the journal Frontiers in Psychology has added more evidence to the pile.
What are lefties good at : Key Takeaways. Making up 10 percent of the population, left-handed people excel in various areas, including art, music, mathematics and sports like baseball and tennis. They even have a higher likelihood of becoming astronauts.
