From superstition and stigma to celebration and skill

Left-handedness has long carried cultural weight—far beyond which hand holds the pen. For centuries, it’s been viewed with suspicion, framed as a weakness, or romanticised as a mark of creativity and talent.

Clean vs. Unclean in Ancient Cultures

In many ancient societies, hands were not equal. In Mesopotamia and Egypt, the left hand was reserved for unclean tasks and came to symbolise impurity. This division filtered into both religious and social customs: the right hand was the hand of greeting, oath-taking, and blessing, while the left was linked to taboo or dishonourable acts.

As one Egyptian saying put it: “The right hand gave blessings; the left carried burdens.”

Shadows of Superstition

Across many languages, the word for “left” has carried a shadow of negativity. In Latin, sinister once meant simply “left” or “on the left side”—a neutral marker of direction. But over time, especially in medieval Europe, the term gathered layers of superstition. The left became entangled with notions of clumsiness, misfortune, even evil. Because right-handedness was the norm, anything different was treated with suspicion. The left hand wasn’t just awkward—it was unsettling. To gesture with it could invite doubt; to write with it could mark you as unnatural.

That linguistic drift is how sinister shifted from a neutral term of direction into English’s modern sense of something threatening or malevolent—a curious twist of etymology. Other languages followed similar paths: in French, gauche means both “left” and “awkward.” These slippages in language didn’t just describe bias, they helped to shape it—reinforcing for generations the idea that left-handedness was something to be corrected, concealed, or distrusted.

Yin and Yang in Chinese Philosophy

In Chinese philosophy, the left side is aligned with yin—the receptive, intuitive, and quietly powerful force that complements yang. While everyday social norms often leaned towards favouring the right hand, this symbolic framing offered a more balanced way of understanding handedness. As one interpretation suggests:

“The left hand belonged to yin—receptive, intuitive, quietly powerful. A reminder that imbalance can still hold wisdom.”

The Push to Conform

Well into the 20th century, left-handed children were often forced to write with their right hand in schools—a practice that could leave lasting frustration or even impact motor coordination. In some professions, being left-handed was seen as a disadvantage: military training, industrial work, and sports all developed around right-handed norms.

I can relate to this, because without even realising it, I often switch between my right and left hand—having been taught at school to do everything the “right-handed” way.

From Stigma to Skill

Yet left-handedness has also been linked to creativity, adaptability, and strategic thinking. Many celebrated artists, leaders, and athletes—Leonardo da Vinci, Marie Curie, Jimi Hendrix, and Serena Williams among them—have been left-handed. The very adaptability demanded by a right-handed world may foster problem-solving skills and unconventional thinking.

Leonardo da Vinci’s Mirror Writing

Leonardo da Vinci, was a proud left-hander, he famously wrote in mirror script—right to left, so that his words could only be read with a mirror. Some say it was a practical trick to keep ink from smudging; others see it as a reflection of his unconventional way of thinking. “Leonardo da Vinci didn’t just write—he mirrored. His left hand shaped inventions, art, and a script that defied convention.”

As a child, I found myself doing the same—filling pages with backwards writing, without even realising I was echoing Leonardo’s left-handed adaptation. For me, it was play; for him, it became a signature of genius.

Changing Perceptions

In recent decades, attitudes have shifted. Specialised tools, sports equipment, and instruments are now widely available for left-handers. Annual events like International Left-Handers Day (13 August) celebrates the uniqueness of the left-handed experience, while research into brain lateralisation continues to challenge stereotypes.

Left-handedness is no longer something to “overcome,” but rather one of many expressions of human diversity—an example of how our differences shape the ways we see, create, and navigate the world.
