How Playing Chess Can Make You Smarter
1. It can raise your IQ
Chess has always had an image problem, being seen as a game for brainiacs and people with already high IQs. So there has been a bit of a chicken-and-egg situation: do smart people gravitate towards chess, or does playing chess make them smart? At least one study has shown that moving those knights and rooks around can in fact raise a person’s intelligence quotient. A study of 4,000 Venezuelan students produced significant rises in the IQ scores of both boys and girls after 4 months of chess instruction.
2. It helps prevent Alzheimer’s
Because the brain works like a muscle, it needs exercise like any bicep or quad to be healthy and ward off injury. A recent study featured in The New England Journal of Medicine found that people over 75 who engage in brain-stretching activities like chess are less likely to develop dementia than their non-board-game-playing peers. Just like an un-exercised muscle loses strength, Dr. Robert Freidland, the study’s author, found that unused brain tissue leads to a loss of brain power. So that’s all the more reason to play chess before you turn 75.
3. It exercises both sides of the brain
In a German study, researchers showed chess experts and novices simple geometric shapes and chess positions and measured the subjects’ reactions in identifying them. They expected to find the experts’ left brains being much more active, but they did not expect the right hemisphere of the brain to do so as well. Their reaction times to the simple shapes were the same, but the experts were using both sides of their brains to more quickly respond to the chess position questions.
4. It increases your creativity
Since the right hemisphere of the brain is responsible for creativity, it should come as no surprise that activating the right side of your brain helps develop your creative side. Specifically, chess greatly increases originality. One four-year study had students from grades 7 to 9 play chess, use computers, or do other activities once a week for 32 weeks to see which activity fostered the most growth in creative thinking. The chess group scored higher in all measures of creativity, with originality being their biggest area of gain.
