Some traditional beliefs about left-handedness are bad, such as in Germany, where people often say “he has two left hands” if he’s clumsy and doesn’t do things well. In the past, people used to find ways to “turn” left-handed people around so that they could join the predominantly right-handed world, so that they could use things like scissors and can openers more easily and look less different. Now, however, people don’t care so much about left-handedness. Many famous people with major achievements are left-handed, such as Goethe, Madame Curie, Mozart, Napoleon, Newton, Kafka, etc. Many scientists have also said that it makes no sense to “turn” left-handed people around. If a left-handed student is suddenly allowed to use his right hand, his writing speed will be difficult to catch up with his right-handed classmates, and his academic performance may drop as a result. That’s why teachers in German schools nowadays don’t “order” a left-handed student to switch to the right hand. Are you really smarter? After counting a number of left-handed celebrities, it has been suggested that left-handed people are smarter. Is this really true? Germany’s Focus Online reported on the 13th, citing a study by University College London, that a survey of 11,000 British children’s hand habits and IQ showed little difference between the average IQ of left-handers and right-handers. Left-handers, however, seem prone to extremes, with a significantly higher percentage of extremely gifted and poor academic achievers. ”The average IQ is the same, but the distribution is different.” said McManus, who conducted the study. According to Focus Online, the results of the annual U.S. math placement test also prove this, with left-handers mostly concentrated at the better and worse ends of the achievement spectrum. Another study shows that in the U.S. workplace, the wages of left-handed people with higher education are 10 to 15 percent higher than those of right-handed people. Why this result is unknown at the moment. Some speculate that it may be because left-handed people need to learn to develop new ideas and solutions earlier in order to adapt to a predominantly right-handed society, which in part stimulates their creativity and ingenuity. More prone to schizophrenia Left-handed people may seem more likely to be geniuses, but they may also be more prone to the other side of genius: insanity. British researchers had found in 2007 that left-handed people may be more prone to schizophrenia, and there is evidence that a gene often found in left-handed people may increase people’s risk of developing schizophrenia. However, researchers believe that left-handed people should not worry about this because many factors can lead to schizophrenia, and the gene found in the study is just one of many. What’s more, there are similar studies that argue against the idea that the risk of schizophrenia is not increased in left-handed people. In fact, many studies on left-handedness are still only at the statistical level and cannot definitively confirm the cause-and-effect relationship, so left-handed people should not worry too much.
