The Internet is plagued by a viral optical illusion that claims to identify whether you are a “right-brain” or a “left-brain” depending on whether you see a fish or a mermaid, because most people see a donkey or a seal instead. .
The viral optical illusion is represented by a series of purple lines against a blue, purple and green gradient backdrop, with the figure giving a divisive response reminiscent of those emanating from the famous blue or gold dress.
According to a photo of the illusion circulating on social media, the people who see a fish are “right-brain”, while “left-brain” individuals are the ones who see a mermaid in the lines.
However, so many individuals, including Harry Potter Author JK Rowling, pointed out that the illusion resembles narrower animals than a donkey or a seal.
“But it’s a donkey,” the author tweeted on March 19, with the response being liked more than 143,000 times.
Others noted that the image was a seal, with actor James Dreyfus responding: “Or a seal. No fish, no mermaid. At all.”
The hundreds of respondents who agreed with Rowling asked a person to recognize that many more people see a donkey or a seal than a fish or a mermaid in the illusion.
“Does anyone see a mermaid? Or, in fact, a fish? It’s a donkey or a seal, sure ??” they wrote, while another said, “First look, donkey. Second look, seal. Never a fish OR mermaid.
The debate also made its way to TikTok, where a user shared a photo of the illusion and said, “I saw this on Twitter. If you have a right brain, you will see a fish. If you have a left brain, you will see a mermaid.And all I see is a damn horse.
While most people were resolute in their belief that the optical illusion portrayed a seal or a donkey, others were madly concerned about their inability to see the mermaid or fish.
“It’s a seal, thank you, so now I have no brain or what?” One person commented on the joke, while another wrote on Twitter: “My brain is broken because I do not know how anyone can see a fish or a mermaid. I see the donkey when I try, but all I see is a seal.
Others note that the illusion is not new, because a version of the drawing, without the colored background, has long existed and is referenced in a 2010 study, published in British Journal of Developmental Psychology about children with autism. In the study, children were asked to determine if a similar line image represented a donkey or a seal.
“Not even sure why this image is on Twitter. This seal / donkey optical illusion is like 100 years old,” one person remarked.
According to Harvard Medical School’s health blog, it is also possible that the theory that individual personality traits reside in an area of the brain is a myth. The blog says that it is typically believed that those who are “right-brained” are intuitive and creative free thinkers who tend to “experience the world in terms that are descriptive or subjective”, while those who are “left-minded” -brained “,” tend to be “more quantitative and analytical”.
However, the blog also notes that there has been “little or no evidence to support the theory”, and that it may be a myth.
“In fact, if you’ve done a CT scan, MRI scan, or even an autopsy on a mathematician’s brain and compared it to an artist’s brain, you’re unlikely to find much difference,” the blog says. “And if you did the same for 1,000 mathematicians and artists, it’s unlikely to produce a clear pattern of difference in brain structure.”
While the university recognizes that more studies need to be done to determine the accuracy of the left / right brain concept, it notes that the authors of a recent study concluded that the notion of some people is “more left-brain or right brain is more of a speech figure than an anatomically accurate description ”after finding no evidence to support the theory when looking at the brain scans of more than 1,000 people between the ages of 7 and 29.
