Left-Handed Footballers at the FIFA World Cup 2026

The tactical demand for left‑footed players should, in theory, lead to a higher proportion of left-handed footballers at the FIFA World Cup 2026 – yet, left-handers are surprisingly scarce among the left-footed players.

The football World Cup is upon us again, and I have to admit that I have a mild football fever these days. I like to watch the occasional match, and the other night, while waiting for the match between France and Senegal to kick off, I found myself scrolling through some random clips of the French national team. What I saw was not really surprising. Just the typical “football stuff”. Players sprinting, kicking, shooting, celebrating, followed by taking selfies with fans or trophies.

Then, I came across a scene featuring Ousmane Dembélé, the central forward of L’équipe tricolore. In the clip, one could see the football star sitting at some gala event, wearing a fine suite, while a football jersey bearing his name was nicely draped on a table in front of him. He was supposed to sign it and so he took hold of a felt‑pen with his his left-hand and graced the jersey with his autograph.

That Ousmane Dembélé prefers to write with his left hand is not remarkable in itself. With around 12% of men being left‑handed [1], any starting line-up of eleven players – at the World Cup or anywhere else – should statistically include about one left‑handed player. And in a sport that mainly revolves around kicking a ball with one’s feet, a player’s handedness should anyway be largely irrelevant, right?

Yet, when I tried to find pictures of the other players of the French squad signing jerseys, fans, or contracts, I came across a curious accumulation of left-handers. Besides Dembélé, also Kylian Mbappé, Adrien Rabiot, Lucas Hernandez, Lucas Digne, Rayan Cherki, and the goalkeeper Brice Samba apparently prefer to use their left hand, suggesting that 7 out of the 26 strong squad – so, roughly 27% – are likely left-handers, more than doubling the expected value of 12%.

With such a small sample, it could easily be a coincidence – and maybe that is where I should have left it. But this finding stuck with me, and I even came up with a little hypothesis concerning the reason for this accumulation of left-handers.

Handedness is strongly associated with “footedness”, in that left‑handers are more likely to prefer their left foot while the vast majority of right‑handers favour their right [2]. To add some numbers: it can be estimated that roughly 60% of all left‑footed individuals should be left‑handed [3]. So, should there be any tactical demand for recruiting more left-footed players, this should – as a side effect – also increase the number of left-handers in a squad.

With which foot a player prefers to “handle” the ball is obviously very relevant in football. It affects the footballer’s playing style, the angles of the passes and shots, or the preferred movement patterns on the pitch. It also may determine the player’s positioning. Left-footed players preferably occupy positions on the left-side of the pitch, and team managers actively search for left-footed players to fill out these positions. If you pay close attention at the World Cup matches, you will find that virtually all left-backs – so those playing on the left side of the defence line viewed from the goalkeeper – are left-footed players. In case of the French squad these are, for example, Lucas Hernandez and Lucas Digne; two of the left-handers mentioned earlier.

Ousmane Dembélé’s footedness is, by the way, a bit more complicated. In a rather remarkable interview early in his career, Dembélé was asked about his preferred foot. His answer was that he was left-footed. Apparently not entirely satisfied with this answer, the journalist inquired why he then shoots penalties with his right foot – as he indeed does as can be seen in the featured image above. Dembélé replied: “Because I shoot better with my right foot.” Maybe this is also the reason why the webpages tracking the careers of professional footballers, such as transfermarkt.com, inform us that he is “both” footed. Or, should we just take his word for it and classify him as left-footed?

In any case, left- and both-footedness is far less common in the general population than right-footedness. Estimates suggests that only about 15 to 20% of men fall into this category [2]. When it comes to football, however, this percentage is nowhere near sufficient. Given the tactical systems most teams employ today, squads typically need three to four capable left‑footed players – around 27% to 36% of the starting line-up – to adequately cover all positions on the left side of the pitch. So, there seems to be a mismatch between the demand for left-footed footballers and the supply of naturally left-footed individuals. As a result, left‑footed players are well sought after, and there are indications for a selection bias in their favour already in young ages [4].

Also at this year’s world cup, the proportion of left‑footed players exceeds what one would expect based on the general population. A quick scan of the full squads of the top-ten teams of the FIFA‑World ranking, finds that 80 left- or both-footed footballers in the total 260 nominated players, so roughly 31 percent [5]. As can be seen in the Figure below, Brazil (11 of 26, or 42%) and Argentina (10 of 26, or 38%) are topping this unofficial left-footedness ranking, but all but two teams show a comparatively high incidence of left-footedness. Only in the English (19%) and the Dutch squad (15%) the proportion of left-footed players is in the “normal”, that is, the expected range.

Left-footedness and handedness of the top-ranked teams at the FIFA World Cup 2026. The footedness information was taken from transfermarkt.com; handedness was determined by finding pictures of the players signing autographs. Left-handed footballers who prefer the left foot, are unexpectedly rare. (Data source: transfermarkt.com, background image from https://pixnio.com/)

Coming back to my earlier hypothesis, the question is whether this high rate of left-footed players also results in an increase in left-handers? The answer is: apparently not! I was able to track down pictures or clips showing 255 of the 260 players of the ten top-teams while writing, and 30 of them were doing so with the left hand – notably including the better known stars Kevin De Bruyne, Joshua Kimmich, Alejandro Grimaldo, or Jordan Pickford [6]. However, this only made for 11.8% of all players, which is arguably very close to the expected 12% left-handers among men. So, no excessive amount of left-handed footballers at the World Cup!

Before wrapping up this excursion into the world of football, I could not resist taking another look at the relationship between handedness and footedness – and, to my surprise, left-handers were astonishingly rare among the left‑footed players. As the graph above shows, both Brazil and Argentina field sizeable groups of left‑footed players, yet each squad includes only a single left-hander. Even more striking, none of the nine left‑footed players on Belgium’s team appears to be left‑handed. Added up across all ten teams, 22 out of the 80 left- or both-footed players (28%) were left-handers: just about half of the 60% percent that could be reasonably expected [3].

It is difficult to say what might have caused this lack of left-handers among the left-footed players. The general need for left-footed players could have forced some right-footed right-handers at young age to practise their left foot to be able to occupy the positions on the left side of the pitch, so that they today appear left-footed. Conversely, many of the left‑footed right‑handers could be natural left‑handers who were retrained to write with their right hand at home or in school. However, the practise of retraining has luckily gone out of fashion in most countries and should not really have affected this generation of players which is born – or at least mostly raised – in the 21st century.

It seems the French squad – including Ousmane Dembélé – is just an outlier when it comes to left‑handed footballers, and my intuitive hypothesis turned out to be one of these misguided attempts of making sense of insufficient data. Among the top‑teams, there are indeed more left‑ or both‑footed players than expected, but this does not translate into a noticeable increase in left‑handedness at the FIFA World Cup 2026.

[1] The incidence of left-handedness is about 2% higher in men compared with women, so roughly 12%; see Papadatou-Pastou, M. et al. (2020). Human handedness: A meta-analysis. Psychol. Bulletin, 146, 481-524. https://doi.org/10.1037/bul0000229

[3] Even when factoring in that right‑handers outnumber left‑handers nine to one, the pattern still suggests that left‑footed individuals should, in principle, be left‑handed more often than right‑handed. According to the data from [2] of 100 men, about 12 should be left-handers of which 66% should be left-footed, so about 8 individuals. Of the 88 right-handers, 6% should be left-footed, so, roughly 5. Left-handed left-footers should outnumber right-handed left-footers 8 to 5 – in percentage, about 60% of all left-footed individuals should also be left-handers

[5] I extracted the data from transfermarkt.com; of note “both”-footedness is rarely reported, so I kept them together with left-footedness for simplicity

[6] Of the total 260 players, Kevin De Bruyne, Joshua Kimmich, and Kylian Mbappé are three of only eight left-handed footballers who are right-footed.

Handedness of Acclaimed Architects: Are Left-Handers More Talented?

By examining the handedness of acclaimed architects the post explores the popular belief that left-handers posses a greater artistic talent than right-handers.

Reading popular‑science articles, blog posts, or online discussions about left‑handedness, one regularly comes across the claim that left‑handers possess a special talent for artistic expression. Ask your favourite generative‑AI chatbot, and you will readily be informed that left‑handers are thought to be over‑proportionally often found in the “creative fields” including visual art, music, or writing [1]. You might even get offered a list of names of supposed left-handed artists as examples for this creative left-handedness, with the likes of Leonardo da Vinci, Pablo Picasso, Vincent van Gogh, Jimi Hendrix, or Lady Gaga, topping that list [2].

While it is not entirely clear where this popular belief in “creative left-handers” originated, one root appears to stretch back to a series of studies examining the handedness of architects. Conducted in the 1970s and led by John Peterson, these studies reported that left-handers were surprisingly common at the Department of Architecture at the University of Cincinnati [3]. Instead of the roughly 10% prevalence expected in the general population, about 29% of the academic staff and 16% of the school’s students were reported to be left-handers. Even more intriguingly, the left-handed students were also more successful. The rate of graduation was about 10% points higher in left-handers than in their right-handed peers.

It is not really surprising that these astonishingly clear findings were taken as evidence for a special talent for architecture among left‑handers. Peterson’s observations were accordingly cited as a key evidence for the formulation of a general theory about human brain development [4]. It was argued that both being left‑handed and having a strong visual‑constructive imagination were the result of an accentuated maturation of the brain’s right hemisphere. This maturation, in turn, was hypothesised to be driven by unusually high prenatal levels of the hormone testosterone.

The validity of this theory has been seriously questioned ever since its conception. Yet, it offers a good story which at the time made it a quite influential theory. So, it is not unlikely that it helped cementing the idea of “creative left handedness” both in the heads of many scientists and, via journalists, also in the public mind.

Considering the handedness of architects, it must be noted, however, that most later studies that attempted to replicate Peterson’s findings failed to do so. And, when I first started looking into the topic early last year, the idea of an excess of left-handed architects was already standing on quite shaky fundaments. Nevertheless, curious, as I was, I decided to have another look at it and I set out to find left-handers among famous architects. I thought if left-handers were indeed predestined to pursue a career in architecture, they should be particularly well represented among the men and women who have left a lasting mark on our cities.

The very first name I typed into “google” was Sir Norman Foster, the British star architect. Even if you are not familiar with his name, I am certain you have come across one or two of his buildings. The Millennium Bridge in London, the renovated Reichstag with its modern glass dome in Berlin, or the 2 World Trade Center in New York, are some of the more famous examples. When watching the first documentary I found about him [5], it became quickly obvious – literally within the first shots – that Foster was sketching his ideas holding the pen in his left hand. And, after consulting some more online material, I was quite convinced, he was, in fact, a left-hander.

Spurred on by this surprisingly quick success, I typed in some other names that came to mind, and I soon landed on the Swiss architect duo Herzog and de Meuron, the minds behind the Elbphilharmonie in Hamburg orThe Bird’s Nest, the stadion built for the 2008 Summer Olympics in Beijing. While one, Jacques Herzog, was clearly right-handed, the other, Pierre de Meuron, was writing and cutting ribbons with his left hand. Bingo! Another left-hander among the famous architects!

It was at this point that I decided to approach my hunt for left-handed architects a bit more systemically. Rather than randomly picking the names of architects that popped to my mind – a source which I was aware would soon run dry – I decided to go into the winner lists of various prestigious architecture awards. I started with the Pritzker Architecture prize, which is sometimes referred to as the “Nobel prize for architecture”, but soon went on to include other national and international awards and prizes in my search for relevant names.

Armed with a set of winners list I began scouring the internet for videos and pictures showing the various architects while they were writing, sketching, or drawing, so I could determine their handedness. And about 600 architects later, I crunched the numbers. Here is what I found [6]:

Only 8% of the architects were left‑handers (or ambidextrous) which was below rather than above the 10% one would expect in the general population. In other words, left-handed architects, like Foster and de Meuron, were not more common than expected.

However, many of the architects on the winners lists had been born and grown up in times in which left-handers were subject to retraining. So, it was not possible to exclude that some members of my sample had been taught, against their inborn preference for the left hand, to write – and maybe also sketch – with their right hand. Ignoring this historical trend would obviously result in an underestimation of the amount of true left-handers in my sample. I had to make sure that this was not the case.

Since the 1950s retraining has gone increasingly out of fashion[7] and by selectively excluding architects born before 1950, it was possible to minimise the effect of retraining on my results. And, doing so, the incidence of left-handedness was indeed increased in this younger cohort. Nevertheless, the corrected rate of 10% did not differ statistically from the expected population rate. Left-handers were also not unusually frequent among the younger architects.

In short, it appears that Peterson’s results stand out as an exception. Being a left-hander instead of a right-hander does not really increase the likelihood for becoming a succesful architect.

Coming back to the common belief in the creative left‑hander, the finding chips away one likely root for this belief, while adding to a growing body of evidence disproving it [8]. Also outside architecture, left‑handers, seen as a group, are neither more creative than right‑handers nor over‑represented in professions commonly considered “creative”. That is, left-handers are likely as talented as right-handers to pursue a career in visual arts, music, design, writing, or architecture.

The Irrational Fear of Left‑Handed Barbers

Historic UK newspapers reveal how left‑handed barbers and left-handed hairdressers struggled for acceptance within their trade.

Mirror, mirror, on the wall. Here I was again, staring at my wet-haired mirror image. My hairdresser had started his work, clipping away, hopefully following my earlier instructions. The necessary small-talk had started – how was holiday? the children? – but soon it had ebbed down again, and only the regular sound of the rapid snip-snip-snip of his scissors could be heard. Again and again, he gathered a small tuft of hair between his fingers before cutting it down to size. Watching this ritual a few rounds, it suddenly struck me: he was holding the scissors in his left hand. Was he left‑hander?

During one of my recent recreational excursions into online newspaper archives, I had stumbled upon a series of articles about left‑handed hairdressers and left‑handed barbers published in UK newspapers. Spanning more than seven decades, these pieces viewed together, offered a striking illustration of how attitudes toward left‑handers have shifted over time. I learned about the prejudice left‑handed hairdressers once faced and the societal obstacles they had to overcome in pursuing their passion for their trade.

The most telling article I found, was the one published in the London-based Pall Mall Gazette in November 1922 [1]. It claimed that many men were afraid of being shaved by left‑handed barbers. As evidence of this sentiment, the article presented an anonymous travelling salesman who, through his work, had encountered countless barbers across the country. The man admitted that he always felt uneasy when assigned to one who was left‑handed. He even confessed to fearing for his life, as though he were placing himself before a double-sinister version of Sweeney Todd [2], and revealed that he would even flee the barber’s chair without a shave whenever he realised he was in the hands of a left‑handed barber:

“Of course, it is foolish, but … I leave the shop on some pretext or other and go elsewhere to be beautified.“

The man’s fear is obviously the result of deeply-rooted prejudice, portraying left‑handers as clumsy and prone to accidents. This scientifically disputed stereotype did not only lead to fleeing customers and other awkward social situations. Apparently, it also manifested itself in the exclusion of left‑handers from certain professions, including hairdressing, as a series of newspaper articles from early 1938 vividly illustrates [3].

In a story unfolding across a couple of weeks, we learn about the case of William R. Shephard, a workless 24-year old from Sunderland, whose dream it was to pursue a career as hairdresser and barber. Accordingly he applied at his local UK government training centre, which at the time provided vocational training to unemployed youth, like him. The training centre, however, did refuse to take him up in the hairdresser programme. Referring to his left-handedness, they rejected his application. As William described it:

“When I was interviewed by members of the panel at the centre … it came out that I was left-handed, and they turned me down.”

Published in the politically left-leaning Daily Herold, the fate of the young man caused a “chorus of protests”. Several outraged left‑handed barbers wrote letters in his support, expressing that they failed to see any reason for banning William from the training programme. It even triggered some deeper journalistic investigations. The training centre was contacted by an unnamed journalist which led to the discovery that the Ministry of Labour had blacklisted left-handers from learning certain professions. Plasters, carpenters, tile fixers, wood-machinists, coach-body builders, sheet-metal workers, and also barbers and hairdressers were supposed to be right handed. Left-handers were barred from these jobs, just because of their handedness.

In the “best” case, this list had been compiled with safety issues in mind and it is not just an expression of prevailing anti-leftie stereotypes. The relevant tools and machines might not have been built to be safely operated with the left hand. But did this concern also apply for hairdressers and barbers? Possible problems with the scissors and shears that are usually made for right-handers?

This seems not to be the case, at least if we believe the words of an also interviewed hairdresser. As he put it, the tools of the trade are – at least with training – usable also with the left hand, and:

“A man who is naturally and actively left-handed should not find it a bar to hairdressing.”

Unfortunately, the articles do not reveal whether the protests actually had made a difference for young William. The general policy of excluding left-handers from hairdressing training, appears not have changed for a while, however, as an article from 1947 suggests [4].

Published in the Liverpool Daily Post, the piece informs us that a training centre – this time located in Aintree, North of Liverpool – was about to start a new women’s hairdressing course, and that one of the required qualifications was for the trainees to be right-handed. The journalist, a Jean Johnson, asked the centre for the reason behind this requirement, and got the following answer:

“Think of the alarm … which would attack a customer if he saw a left-handed barber coming at him with a razor”

Together with the journalist, we are left wondering what this argument has to do with women’s hairdressing. It appears, the prevailing prejudices were considered sufficient explanation by the training centre, while any good argument for excluding left‑handers was simply missing. Although not stated explicitly, one can speculate that the list barring left‑handers from the trade was still somewhat guiding the centre’s decisions. Yet rejecting left‑handed applicants at a government‑run training centre, without any comprehensible reason, could well be regarded as a form of institutionalised discrimination.

Luckily, times change, and forwarding history by about 20 years, there is evidence that the training centres’ policy had finally been adjusted. In an issue of the Daily Express from 1968, we are introduced to Roderick Robins from Swindon [5]. He was a young aspiring hairdresser, who had recently finished his education as hairdresser in a training centre in Bristol. The centre, according to a spokes person, had only recently accepter left-handers as hairdressers. And, they even had equipped Roderick with two pairs of true left-handed scissors.

So, one would have hoped, Roderick’s career as left-handed hairdresser was off to a good start. But that was unfortunately not the case. Although he was well-trained and had passed his final examination with success, no hair salon was willing to employ him because – you guessed it – of his left-handedness. He is quoted complaining:

“Hairdresser still treat left-handers and left-handed scissors as a joke … One man hired me on a week’s trial. Then he said there was no such thing as a left-handed hairdresser.”

Again, the article does not provide any clue about the fate of Roderick and his career. But we learn, that at least his “blonde girl-friend Judy,” happily volunteered as his customer (as seen in the feature image above).

In any case, Roderick’s story shows that in 1968 left‑handed barbers or hairdresser still were even more exceptional than left-handedness itself. In yet another article from the same year and published in The Derby Evening Telegraph, we even get a description of exactly how rare left‑handed barbers were at the time [6]:

“Like straight bananas, pink elephants and de Gaulle saying ‘Oui’ instead of ‘Non,’ the species [left‑handed barbers] would appear to be something of a myth”

The article does not fail, however, to present such a mythical creature to the reader. It is named Mr. Alfred Martin, a left-handed hairdresser who ran his own salon in a small town close to Nottingham, and who, according to his own assurance, never really had any problems with his handedness. I am not sure how poor William and Roderick might have felt reading this statement.

The final article I discovered on the topic is from 1996. In honour of the in the meantime introduced and celebrated Left-Handers Day, the Bicester Review ran a story about the hairdresser parlour Francine Salon [7]. We are told that the staff of this salon consisted of a crew of four talented hairdressers – the owner Francine Porter, her twin sister Jacqueline Huntley, a Kerry Barnes, and trainee Tracy Woods – all four of them left-handers! What are the odds?!

The article shows the hairdresser quartet smiling cheerfully at the camera (see cover picture above), and it is clearly meant as a light‑hearted piece to entertain the newspaper’s readers. Notably, it is the first article in my modest collection that does not invoke any prejudices about left‑handers or mention discrimination of any kind. The public attitude toward left‑handedness seem to have changed, and the narrative is no longer focussing on the negative stereotypes. Left-handedness does no longer really matter. Well, at least not to right-handers.

The practical everyday challenges of being a left-hander in a right-handed world do still remain. Francine offered a small glimpse into these challenges, recalling what she encountered at the beginning of her own career. She is quoted:

“When I was trained by a right-hander I had to look in a mirror … That helped me get my angles right.”

Manual skills, like making knots or using tools and scissors, are learned faster when the person demonstrating it – the model – has the same hand preference as the learner [8]. Observing the model in the mirror, and virtually reversing the model’s hand preference, sound like a viable strategy to improve learning the tricks of the trade.

Talking about mirrors “switching” handedness brings me back to my own hairdresser in the year 2026. I was just about to ask him about his experiences as a left‑handed hairdresser. Had he faced any challenges during his training? Had he ever encountered discrimination because of his handedness? But before opening my mouth, I decided to double‑check what I thought I had seen.

After engaging in an embarrassingly long struggle with the confusing nature of mirrors, I had to revise my initial conclusion. He was, in fact, operating the scissors with his right hand, after all. Not that it really mattered, of course, but still I felt a small sting of disappointment. He was just an ordinary right‑hander – just like myself.

In the original illustrations from 1846/1850 he was depicted right-handed, and in Stephen Sondheim’s musical adaptation from 1979, Todd is supposed to say “My right arm is complete again” when holding up the razor-come-weapon in his stretched out right hand.

Sinister Muppets: Why Miss Piggy and Kermit are Left-Handers

The post explores the reasons for why most of Jim Henson’s muppets are left-handers.

Browsing the catalogue of my favourite online library, I came across a book entitled Celebrated Left-Handers [1], which promised fabulous facts about these famous lefties. Curious as I am about all matters of handedness, I was intrigued and began leafing through the pages.

The book, published in 1999, was structured like a calendar. For each day of the year, it introduced a notable left-hander born on that date. There were many actors, sport stars, and various heads of various states, including a couple of U.S. presidents. I quickly realised, though, that the book was not always correct, as it featured a few – let’s say – honourable left‑handers, who almost certainly are right-handers. The then-prince-now-king Charles III of the United Kingdom, is one such example. The author apparently considered these celebrities important enough to grant them a place of honour among the genuine left‑handers.

One other of these supposed “lefties” can be found as entry on the 24th of September: Jim Henson, the American puppeteer. Should his name not immediately “ring a bell”, you will very likely recognise one or two of his creations, those anarchic characters Henson lovingly called muppets. You have likely encountered them in shows like Sesame Street or The Muppet Show. The stars of these shows, like Ernie and Bert, Kermit the Frog, or Miss Piggy, have left a lasting impression well-beyond children’s TV, and you might well have encountered them in other branches of popular culture .

Henson was, however, very likely a right-hander. He wrote and drew with his right hand and he, as you will see in a moment, controlled this puppets the way right-handers typically do. Although Henson certainly deserves to be mentioned in any book on celebrated people, the inclusion in this book on left-handers was very likely a mistake.

There were, nevertheless, a couple of lines in the paragraphs describing his work and life that caught my attention, as it suggested that one of his creations might well be a left-hander. It reads [2]:

“One of the earliest and most popular Muppets was … Kermit the Frog, who eventually became a kind of alter ego for the low‑key and essentially introverted Henson. Kermit was, like his creator, left‑handed.”

My curiosity was tickled, and I could not help but diving a bit deeper into this claim. I had to study Kermit’s handedness. So, rekindling my childhood fascination for Henson’s shows, I rewatch countless clips of Kermit acting on Sesame Street and in The Muppet Show – and indeed, it was true. Kermit clearly preferred his left hand, or whatever the frog equivalent of a hand his called by biologists. I found him holding micro- and telephones, pressing buttons, and even smashing cakes – always favouring his left hand. And during his iconic banjo routines, he strummed away with that same left hand leading the show.

And, to my surprise, Kermit was not the only leftie on the cast of these shows. Rather, most muppets seem to prefer their left hand. Bert, Ernie, the Count, Grover, Cookie Monster, Beaker, Floyd, Janice, Statler and Waldorf, all the characters I remembered from my childhood, turned out to be left-handers. Even Miss Piggy, the resident diva of the Muppet Show. You can watch her acting out her temperament, regularly hitting Kermit and other with her devastating left-hand swing.

As lively as Henson’s creations appear on screen, they are obviously just glove puppets. They are brought to live by the hands of various human puppeteers. And, it is not a very daring prediction to make that the Muppet’s left-handedness is, in one way or the other, reflecting the hand preference of these puppeteers.

So, I had to look at the puppeteers. As said, Henson was a right-hander, and so were most in his team. For example, Frank Oz, is a right-hander. He played among other the muppets Bert and Miss Piggy, and, by the way, also worked on the original Star Wars movies. Yes, in Yoda, his hand he had. And it turns out that right-handed puppeteers, like Oz and Henson, typically prefer to wear the glove puppet on their dominant right hand [3].

The picture below, which was taken at the recording of the Sesame Street, nicely illustrates this. On the left, you can see Frank Oz controlling Bert, the yellow fellow, who is a type of a glove-and-rod puppet. The glove part is the head of Bert, which is here operated by Oz with his right hand stuck in the puppet’s back. This leaves Oz’s left hand free to operate the rods or sticks controlling the hand and arm movements of the puppet. As Bert’s left hand is closer to Oz’s free left hand, Oz naturally prefers to use the left hand of Bert when interacting with the props or when gesticulating, making Bert appear to be a left-hander.

Similarly, on the right side, we see Jim Henson controlling Ernie, the orange chap. Ernie is a slightly different type of puppet than Bert as his hands are not controlled by rods. Rather he is a live-hand puppet, and has two gloves as hands, significantly increasing his manual dexterity compared with Bert, but also, as seen in the picture, requiring a second puppeteer when actions of both hands are required. So, Henson controls Ernie’s head with his right hand, while wearing a second glove representing the muppet’s left hand on his own left hand. Ernie’s right hand, in turn, is controlled by the second puppeteer wearing the glove – a process fittingly called right handing in the trade – which here is done by Daniel Seagren. Nevertheless, since Henson is the lead puppeteer of Ernie, it will naturally be him who leads the manual acting with his and Ernie’s left hand.

So, it appears, Henson’s muppets – and likely most other glove puppets – end up as left-handers simply because the nervous systems controlling them are usually right-handers. Right-handed puppeteers animate left-handed puppets.

Of course, not all people are right-handed, and the occasional left-handed puppeteer should animate right‑handed puppets. And, indeed, this seems to be the case. Louise Gold was one such puppeteer on The Muppet Show. She played various characters including the recurring Annie Sue – Miss Piggy’s younger pig rival. Gold used her left hand to control Annie Sue’s head and her right hand to guide the arm rods. Annie Sue accordingly turned out to be a right-handed muppet.

These observations enable us to speculate about the handedness of the muppets and puppets seen as a population. About 10% of the human population are left-handers [4], and there is no reason to doubt that puppeteers are somewhat representative for this population and exhibit a similar incidence rate of left handedness. The muppets controlled by these left-handers will likely appear right-handed, while the other 90% will typically turn out to be left-handed. In other words, in muppets right-handers are probably as infrequent as left-handers are among us humans.

Henson’s muppets, as most other puppets, are caricatures, accentuating our human quirks, anxieties, and peculiarities in their acting. Watching their shows, offers us a mirror, in which we can recognise ourselves or people we know. And, as for any proper mirror, left and right are also confused here, and most puppets appear left-handers.

Left-Right Confusion in Left-handers: The Case of Mr. Macdonald Hastings

Inspired by the case of the British journalist Douglas Macdonald Hastings, the post explores the phenomenon of left-right confusion in left-handers.

Douglas Macdonald Hastings (1909 – 1982)[1] was a British author, television broadcaster, and journalist. He became known to a wider UK audience through his World War II reporting for the Picture Post magazine, accompanying the troops during their campaign to liberate France. In the end of the 1950s, he also was a familiar face on the BBC programme Tonight, and over the course of his career he authored numerous books, including several detective novels.

According to piece he published in the London Newspaper The Evening News in April 1937, he also was a left-hander [2].

In this rather intriguing article, Hastings offers a glimpse into the life of a left-hander born in the early 20th century UK. He complains that the society he is living in, is biased against left-handers. In a world dominated by right-handers, left-handedness is considered a significant flaw:

Titel of Mcdonald Hastings article, published in The Evening News, April 27th, 1937. (source: https://www.britishnewspaperarchive.co.uk/)

“Just because right is might, anybody that isn’t right must be wrong”.

He recalls that he had been made to write with his right hand in school, against his innate inclination to draw and paint with his left hand. A common practise in schools of that time. But he also reports that these challenges did not stop with childhood. He describes the concerned look on the faces of his right-handed friends that appeared whenever he picked up a knife with his left hand to slice bread. These looks were often accompanied by well-meant comments that, however, unmasked the latent prejudices his friends held against him as a left-hander:

“it is certain that someone will warn me to be careful not to cut myself”

Surprisingly, however, Hastings himself appears not to be entirely free from such stereotypes. He starts the article with a strong warning about his ability to give directions, a deficit, which he directly attributes to his left handedness. It reads:

“If you chance to meet me in the street and, politely raising your hat, ask me the way, don’t believe a word I tell you. Better than that, if you hope to reach your destination, do precisely the opposite to my instructions. That is not because I don’t know the way […] Neither am I of an anti-social disposition. It is simply that I am unable to distinguish between left and right. I am left-handed.”

The phenomenon he describes is known as left-right confusion. It refers to a person’s difficulty in reliably and rapidly distinguishing left from right – whether on one’s own body or in external space, as for example, when giving directions. The reasons for suffering from this phenomenon are not known, but it is typically not tied to any medical condition. What is known, however, is that left-right confusion is remarkably common. Recent studies estimate that approximately 15% of the general population experience it regularly [3].

Supporting Hastings’ suspicion, some studies did indeed suggest that left‑handers experience left-right confusion more often than right‑handers. However, these earlier findings have not consistently been replicated, and modern accounts typically contradict the notion of a meaningful difference between left- and right-handers.

One recent example is a study by Hikari Yamashita conducted at the University of Osaka, Japan [4]. He tested each 64 left‑ and right‑handers in a map-navigation task. Participants were asked to follow a predefined route on a map placed in front of them and, at each of 32 turning points, they had to state whether a “left” or “right” turn was required. Left- and right-handers showed comparable performance: both the number of errors and the total time needed to complete the route were similar.

So, Hastings was likely wrong in blaming his left-handedness for the left-right confusion. It appears more plausible that he, by mere chance, had been a member of two minorities: the 10% of the population that are left-handers, and the 15% of population that mix left and right. It was a coincidence, not a causal relation in any direction.

Should you, like Hastings, often find yourself confusing left and right, he also offers a memory hook to help in such situations. Follow your heart! It usually beats on the left side of the body. Unless, of course, you happen to have an extremely rare condition called situs inversus [5], in which case the logic is naturally reversed. But that is a different story altogether.

Retraining of left handers: evidence from 19th century caricature

A caricature from 1856 reveals that the retraining of left handers was a recognised practise in 19th‑century Germany.

On one of my virtual excursions into the excellent digital historical library of the University of Heidelberg [1], I came across the weekly Bavarian-German magazine called Fliegende Blätter, so, Flying Pages. Founded in 1844, the magazine ran for more than 100 years, and was widely appreciated for its sure‑footed, satirical portrayal of the German bourgeoisie.

The caricature above, which I found in a 1856 issue [2], nicely reflects this sentiment. It is drawn by the physician and artist Ferdinand Schröder and entitled Das Mutterauge, the eye of a mother. And with this eye, the mother observes how her dear little boy Emil is about to hit his (likely) nanny with a stick. The mother does not like what she sees and, as every good mother would, decides to intervene, although for slightly different reason than expected.

“Aber lieber Emil, wie oft soll ich es Dir denn sagen?!“, she exclaims, “Schlägst Du schon wieder mit der linken Hand!!“

Translated:

“But dear Emil, how often do I have to tell you?! Again you are hitting with your left hand!!“

The dear son is using the wrong hand! He should rather hit the poor nanny with the stick in his right hand! This unexpected reason for the intervention is obviously meant as a social criticism. The servants do not really matter to those wealthy people. The seemingly trivial matter of the son’s hand preference is more important than the well being of the nanny. A moral bankruptcy.

The caricature does also show, however, that the retraining of left handers — the forced conversion of children to use their right instead of their preferred left hand — was “a thing” in mid-19th century Germany. Using it as a topic for mocking the rich people assumes that the reader is familiar with the concept. And indeed, it can be expected that retraining was quite frequently done at this time, and not only in Germany.

Today, we know that left handedness is at least partly determined by genetic factors [3], letting it appear barbaric to retrain a child against its innate preference. In the 19th century, however, it was usually assumed that handedness is just a matter of education and upbringing. And a person brought up well, so the common opinion, was to be right handed. A rule of proper etiquette. Real or want-to-be bourgeoisie parents had to train their children to write with their right hands. Raising a left-handed child, or being openly left handed, would have been a social embarrassment.

The retraining has luckily increasingly gone out of fashion, and left-handed members of Gen Z living in Europe or North-America will likely not have suffered through it. But many left handers of earlier generations[4] or of different cultural origin [5] have certainly experienced retraining. So, unfortunately, there are still too many out there with a first-hand experience of retraining.
