9) Animals too have left handedness.
Research says left-handedness is not just restricted to human species, but seen in animals as well. Around 50% of cats and rats are left-handed, according to research. Veterinarian Janice Lloyd told ABC Australia that in her research, she found nearly 50% of dogs favoured their left paw.
10) 10-12% percent of the world’s population is left-handed.
The percentage of lefties across the world is slowly growing. Do you know there are 30 million left-handers in the U.S.? On average 10-12% of the world is left handed while 87% is right-handed. Scientists suspect that more people are born as lefties and then convert as righties later in life.
Professor Daniel M. Abrams and graduate student Mark J. Panaggio at Northwestern University created a model that shows the low percentage of lefties is due to the balance between cooperation and competition in human evolution.
“The more social the animal—where cooperation is highly valued—the more the general population will trend toward one side,” says Abrams, an assistant professor of engineering sciences and applied mathematics at the McCormick School of Engineering and Applied Science.
“The most important factor for an efficient society is a high degree of cooperation. In humans, this has resulted in a right-handed majority.” On the other hand, competition does the complete opposite and resulted in 10% of the people turning lefties.
11) Every August 13th has been celebrated as “Left-Handers Day” since 1996.
The UK based Left-Handers Club launched 13th August as the International Left-Handers Day in 1996 to increase awareness about the left-handed lifestyle.
Their website marks this as a day “when left-handers everywhere can celebrate their sinistrality and increase public awareness of the advantages and disadvantages of being left handed.” The day is celebrated with events since lefties make up only about seven to 10% of the world’s population. These events include celebrating a left-hander’s creativity, adaptability, and athleticism.
12) Some of the noteworthy political leaders in history are lefties.
Out of the last seven US presidents, 4 have been left handed. President Obama, Bill Clinton, George Bush, and Gerald Ford, as well as few Presidents in the past like James Garfield and Harry Truman, are also left handed. So, lefties are highly likely to be great leaders!
13) Their average salary is 9-19% lower than the right-handed people.
Statistics show that Left handed college graduates go on to become around 26% richer than their right-handed counterparts. A lot of royals are left handed too! Lefties in the British royal family include the Queen Mother, Queen Elizabeth II, Prince Charles, and Prince William.
However, a 2014 Harvard study revealed that the average salary of lefties is nine to 19 per cent lower than for right-handed people. The left-handed participants scored lower than righties on cognitive tests, and are more likely to have emotional and behavioural problems. Aside of that lefties tend to suffer from learning disabilities at a higher rate and complete less schooling. Altogether it lowers their ability to earn more than their right-handed peers.
14) They are better at 3D perception and thinking.
As mentioned earlier, the human brain is cross-wired meaning the left hemisphere controls the right-handed side of the body and vice-versa. So left-handers can boast they are always in their right mind. Because their right hemisphere of the brain dominant, which controls music, art, creativity, perception, emotions, and genius.
So left-handers are more likely to be creative and visual thinkers, better at 3D perception and thinking. This explains why there are more left-handed architects than righties.
15) 40% of schizophrenics are surprisingly left-handed.
Yale University researches concluded that around 40 per cent of schizophrenic patients were left-handed, with theories suggesting that brain laterality plays a role. This is one of the most uncool facts about left handed people.
16) They are also likely to get easily embarrassed.
According to research done by scientists from Abertay University in Scotland, lefties tend to feel more shy, inhibited, critical self-observers as compared to their right-handed counterparts.
