We hope you Lefties are celebrating today.

Happy Left Handers’ Day!

NPR’s reporting on left-handedness covers two main topics: the causes of left-handedness and successful people who are left-handed (mostly presidents and baseball pitchers). 

This story, from a special series, Science Outside of the Box, takes an interdisciplinary approach to the question of left-handedness.

NPR’s Jacki Lyden talks to researcher Chris McManus who examined archived film footage of British people waving at the camera to see what he could learn about left-handedness, society, and life in the Victorian era.

Scientists think that most left handed people are mirror image twins where one was absorbed by the other in the womb.

I’m left handed.  I’ve always kind of wondered what my twin would have been like had I not eaten them.

I literally just realized I’m the evil twin.

Why Being Gay is Like Being Left-Handed

-Society assumes you’re right-handed unless you say otherwise

-Society makes products specifically for right-handed people and expects left handed people to “just adapt” to using right-handed products

-When a product is made specifically for left-handed people, right-handed people don’t understand why someone who is left-handed would specifically need that as a left-handed product

-Sometimes people try to make you use your right hand instead, claiming that using your left hand is “wrong”

-People get stunned when they notice that you’re left-handed, and feel the need to ask you questions about your left-handed “lifestyle”

-When a left-handed person mentions that they’re left-handed, a right-handed person will say “I don’t tell people that I’m right-handed, so why do you need to announce to the world that you’re left-handed?”

-Children of a left-handed person will ask their parent why there aren’t books, tv shows, or movies about their family, because each character is portrayed as being right-handed

Study finds lefties are worse off than righties, economically speaking 

If you’re left-handed, you’re in for a rough life.

A new study by a Harvard University economist spells bad news for the 12% of people in the world who are lefties: Lefties earn a considerable amount less money than their right-handed peers. Upon examination of data from the U.S. and the U.K., Harvard professor Joshua Goodman found that lefties earn between 10% and 12% less every year than righties do.

The pay gap between lefties and righties becomes even starker when examined through the gender lens.
