I once had a leftie writing contestant. She was so grammatically smart I only taught her the rudiments of writing: outlining, making topic sentences, inserting facts and figures, ending it right and presto! She brought us to national fame.
One of the more memorable years in our tandem were the division, the regional and national press conferences.
The last she made it was when we won the prestigious national On-The-Spot-Essay Writing Contest sponsored by the Knights of Rizal in Baguio City shortly before she transferred school to pursue her senior high.
Are left-handed individuals really that smarter?

It is estimated that between 10% and 13.5% of the population are not right-handed. While a few of these people are equally comfortable using either hand, the vast majority are left-handed.
Hand preference is a manifestation of brain function and is therefore related to cognition. Left-handers exhibit, on average, a more developed right brain hemisphere, which is specialized for processes such as spatial reasoning and the ability to rotate mental representations of objects.
Also, the corpus callosum – the bundle of nerve cells connecting the two brain hemispheres – tends to be larger in left-handers. This suggests that some left-handers have an enhanced connectivity between the two hemispheres and hence superior information processing. Why that is, however, is unclear. One theory argues that living in a world designed for right-handers could be forcing left-handers to use both hands – thereby increasing connectivity. This opens up the possibility that we could all achieve enhanced connectivity by training ourselves to use both hands.
These peculiarities may be the reason why left-handers seem to have an edge in several professions and arts. For example, they are over-represented among musicians, creative artists, architects and chess players. Needless to say, efficient information processing and superior spatial skills are essential in all these activities.
How about in handedness and mathematics, fellas?
Who’s smarter — righties or lefties?
Shana Lebowitz says: As is so often the case with social science research, the frustrating answer is “it depends.”
But there are certain cognitive domains where left-handed people do seem to excel. One such area is called “divergent thinking,” or the ability to generate new ideas based on existing information.
That’s according to 1995 research by psychologist Stanley Coren, which was cited more recently in a New Yorker article. Coren conducted several experiments that suggest left-handedness is associated with superior divergent thinking, at least in men.
In one experiment, nearly 1,000 men and women had to think of ways to combine two commonplace objects not typically used together, like a pole and a tin can. In another, participants had to organize a series of words into as many different categories as possible. Results showed that left-handed men performed better on these measures of divergent thinking than right-handed men — although there was no such difference for women.
Coren was able to effectively rule out the possibility that lefties are simply smarter overall by administering a test of convergent thinking, which involves applying existing knowledge and rules to come up with a correct answer. Participants had to indicate which word in a series didn’t fit the pattern — and righties performed slightly better.
In the paper, Coren notes that his results might help explain why lefties are more common among mathematicians, architects, artists, and chess experts.
More recent research, cited in the New Yorker article, has found that lefties demonstrate superior spatial skills, mental flexibility, and working memory.
So, are you a leftie, fella?
Cheers! You have all the reasons to be proud.
