Chess won't make your kid smarter. Teach it anyway.

Every chess set marketed to parents comes with an invisible promise printed on the box: this will make your child smarter. It is the reason chess lands on lists of brain-boosting activities, and the reason a parent feels a little virtuous setting one up. I want to make an unpopular argument. That promise is mostly false. And it does not matter, because you should teach your child chess anyway.

I did not learn chess to get smarter. I learned it on the floor, losing over and over to a cousin who was simply better than me, in a house where a board happened to be lying around. Nobody called it enrichment. It was just a game that pulled me in. That is the relationship with chess I would want for any child, and it has nothing to do with a test score.

What the research actually says

Here is the honest version, because you deserve it. The studies that built the "chess makes kids smarter" industry did show gains, modest bumps in maths and cognitive scores. But almost none of them compared chess against an active control group. That means we cannot tell whether chess did the work, or whether any fun, structured, attention-demanding activity would have done the same. A child who spends an hour a week being taught something carefully will usually test a little better afterwards. That is not chess. That is attention.

When researchers looked harder, the effect thinned out. Giovanni Sala and Fernand Gobet, who have studied this more rigorously than anyone, concluded that far transfer mostly does not exist. Getting good at chess does not reliably make you better at unrelated things like maths. The wider review of the field makes the same methodological point. What that leaves, and the reading I find most convincing, is probably selection rather than cause: sharper children take up chess and stay with it, rather than chess sharpening them. The arrow most likely points the other way.

So if you are buying a chess set as a brain investment, the evidence is thin. I would rather tell you that than sell you the poster.

Why I teach it anyway

Because the real reasons chess is worth a child's time were never going to show up on a test.

Chess teaches a child to sit with a hard problem without flinching. To look before they move. To imagine a consequence before it arrives, to be wrong, and to try again. It teaches the specific, unglamorous patience of waiting while someone else thinks. And it teaches the hardest thing of all, which is how to lose, shake hands, and set the pieces up again. None of that is measurable. All of it matters more than another point on a maths paper.

There is also the thing nobody prints on the box. Across a chess board, a parent and a child are doing something together that is neither a screen nor a chore. The phone is down. You are both just there, thinking, inside the same small world of sixty-four squares. I am not convinced a test score is worth more than that.

What I am really arguing against

My objection is bigger than chess. Somewhere along the way we turned childhood into an optimisation problem. Every activity now has to be justified by what it improves. Music for the maths brain. Coding for the future job. Chess for the IQ. The child quietly disappears, and what is left is a portfolio.

I do not want to play that game, and I do not think it produces happy children, or even, in the end, high-achieving ones. A thing does not have to make your child smarter to deserve a place in their week. It only has to be good. Chess is good. It is one of the great human games, it has given a quiet kind of joy to people for centuries, and a child who comes to it on their own terms can keep it for life. That is the whole case. It does not need a study stapled to it.

So teach your child chess. Not as an upgrade. As a gift. Sit on the floor the way my cousins and I did, lose a few games on purpose and a few for real, and let them fall for it without ever telling them it is good for them. If they do fall for it, they will get sharper at chess, which is the one thing chess reliably makes you better at. And they will have a game for life. That is enough. It was always enough.

If you want help keeping it going week to week, that is what we built Summiva for, and the practical how-to lives in the parent's guide to chess for kids. But the plan is the easy part. The hard part is resisting the urge to make it about anything other than the game. And if you want a gentle way to step back and just ask what your kid actually dreams about, we made a free Dream Sheet for that.
