However,
Lefts more creative than right:
The myths on the left -handers have always existed. Nevertheless, Formerly persecuted. Furthermore, forced to become right -handed, left -handed were later considered to be smarter and creative people than right -handers. Moreover, But what does science say? Moreover, Researchers have traveled more than a century of studies conducted on the subject. Furthermore,
No, left-handed are no more creative than right-handers, according to a study by researchers from Cornell University (New York). Similarly, To reach this conclusion. Meanwhile, the latter peeled over a hundred years of study that explored the links between left -handers and creativity.
A “simply unfounded” idea
This meta-analysis is based on nearly 1000 scientific articles published since 1900. It reveals that laterality has little effect on the three most common laboratory tests to detect a divergent thought. Divergent thinking, or creativity, is a method of thinking used to produce lefts more creative than right creative ideas by considering many possible solutions.
The available scientific data even show that right -handers have a slight advantage on certain tests, compared to left -handers.
« If we examine literature as a whole. the assertion that the left -handers are creative is simply unfounded », said Daniel Casasanto, Associate ProfessorAssociate Professor of psychology and co -author of the study published in Psychonomic Bulletin & Review The scientist affirms that in reality, it is right -handers that are over -represented in the professions requiring increased creativity.
Where does this belief come from?
There are scientific reasons to believe that left -handed. which represent around 10 % of the population, would have an advantage in mattermatter creativity. The latter. which can be defined by the ability to explore many possible solutions to a problem in a short time and establish lefts more creative than right unexpected connections, is more favored by the right hemisphere of the brain. However, left -handed people generally have a dominant right hemisphere.
This false belief was also maintained by another factor, the researchers argue: the exceptionalism of left -handers. We all know that left -handers are rarer than right -handers. Likewise, we consider that creative geniuses are rare pearls. One may explain the other.
What has also fueled this belief is the widespread perception that creative engineering is linked to mental illnesses. It turns out that left -handers, more likely to be artists, have higher levels of depression and schizophrenia.
« This idea that being left -handed. art and mental illness go hand in – what we call it “myth of the tortured artist “ – could contribute to the appeal and sustainability of the myth of creativity of left -handers », analyze Daniel Holy.
An urban legend fueled by biased lefts more creative than right studies
Finally. the researchers point out that this urban legend takes root in a small number of studies relating to limited or biased samples. Studies that often focus on two creative professions, art and music, where left -handers are over -represented. For Daniel Casasanto, it’s ” A common and tempting statistical error that humans constantly commit ”.
“We generalized by thinking that there were all these left -wing artists. musicians, and that left -handers had to be more creative. But if we conduct a impartial investigation into many professions, this apparent superiority of left -handers disappears ”he concluded.
