Does Chess Make You Smarter? Studies & Scientific Evidence

Does chess really make you smarter? The question has fascinated scientists and educators for decades. While the link between chess and IQ is more nuanced than often thought, the cognitive benefits are real. The benefits of playing chess on intelligence are scientifically documented, and the game’s effects are backed by research. Here’s what the science says.

What the scientific studies show

Several major studies have explored the link between chess practice and cognitive abilities. Here are the most significant:

Study	Year	Key finding
Venezuela study	2000	4,000 pupils: those practising chess improved their maths and reading scores by an average of 17% compared with the control group.
New England Journal of Medicine	2003	Adults aged 75+ who play strategy games (including chess) reduce their risk of dementia by 74% compared with non-players.
University of Tübingen	2006	MRI scans show that expert chess players use both brain hemispheres simultaneously, whereas beginners mainly use the left.
Sala & Gobet meta-analysis	2016	An analysis of 24 studies: chess improves maths performance and general cognitive abilities in children, though the effect is modest.

The real benefits of chess

Chess doesn’t magically add 20 points to your IQ. But it does develop specific, measurable cognitive skills. For a complete overview, discover our article on the 7 benefits of chess for your mind.

Concentration and attention

A chess game demands 30 to 90 minutes of uninterrupted concentration. This ability to sustain attention carries over into study and work. Children who play chess show improved attention span in the classroom.

Working memory

Calculating 3 to 5 moves ahead places heavy demands on working memory (short-term memory). Regular players show superior performance in tests of visuo-spatial working memory.

Problem-solving

Every chess position is a complex problem with multiple solutions. Players learn to weigh up options, anticipate consequences and decide under time pressure — skills directly applicable to professional life.

Emotional management

Accepting defeat, staying calm under pressure, coping with the frustration of a mistake: chess is a school of emotional resilience. This is a benefit that’s often underestimated, and it’s particularly valuable for children.

Chess according to age

Children (5-12 years)

This is the age at which the benefits are most pronounced. Chess develops logic, patience and self-confidence. More than 30 countries include chess in their school curriculum. In France, the FFE runs sessions in primary schools.

Teenagers (12-18 years)

Chess strengthens strategic thinking and decision-making. For teenagers, the game also offers a positive social setting and a constructive alternative to passive screen time.

Adults (25-65 years)

The game keeps the mind sharp and provides a space for mental decompression. Playing a game in the evening is a far more stimulating mental exercise than watching television.

Seniors (65+ years)

The NEJM study (2003) is clear: strategy games protect against cognitive decline. Geriatricians recommend chess as a brain-stimulating activity, on a par with crosswords or reading.

Chess in schools

In 2012, the European Parliament passed a resolution recommending the introduction of chess in EU schools. In France, the French Chess Federation’s “Chess at School” programme reaches thousands of pupils every year. The results are encouraging: children who play chess show better understanding of mathematics, improved concentration and better social skills.

The IQ debate: Does chess make you smarter, or are intelligent people drawn to chess? The truth is probably both. Studies show a modest but real benefit of practice on cognitive abilities, especially in children. But the effect is maximised when chess is combined with other intellectual and physical activities.
