The prisoner’s dilemma: why smart talent developers still try to recruit children too young

I recently made a return appearance on The Real Science of Sport Podcast hosted by Professor Ross Tucker and Mike Finch. We talked about some of the challenges for parents who are raising talented youngsters and we talking about some of the perverse incentives driving the behaviour of people in the talent development world. Then I was watching this YouTube video about the way companies that are making lay offs by replacing people with AI, and how this was actually going to destroy their own businesses in the long run. They made reference to 'the prisoner's dilemma' as a way to explain that the companies would actually be better to work together to survive long term rather than thinking that they should get one over on the competition by laying people off. It got me to thinking about the prisoner's dilemma in the world of talent development. So what is the prisoners dilemma?

Imagine two crime suspects are held in separate rooms. Each is offered the same deal, and the numbers make it hard to argue with. If both stay silent, each serves one year. If both talk, each serves five. If one talks and the other stays silent, the talker walks free and the silent one serves ten.

Sit in the first suspect’s chair. If the other stays silent, talking gets you zero years instead of one. If the other talks, talking gets you three years instead of five. Whatever your partner does, talking is better for you. They reason the same way, so both talk and both serve three years, six in total. Had they trusted each other, they would have served two between them.

That is the cruel irony… each person acts rationally, and the result is worse for both than the one they could have reached together.

Where the idea comes from

Merrill Flood and Melvin Dresher devised it at the RAND Corporation in 1950, while the United States was working out how to think about nuclear rivalry. Albert Tucker, a Princeton mathematician, wrapped it in the prison story soon after to explain it to a room of psychologists, and the name stuck.

Philosophers had been circling the idea for centuries. Thomas Hobbes got there first, in Leviathan (1651). His state of nature was a prisoner’s dilemma with a whole population in the room. Everyone would prefer peace, but nobody can safely put down their weapon while a neighbour keeps theirs, so everyone strikes first and life ends up “solitary, poor, nasty, brutish, and short”. His answer was a sovereign with the power to enforce agreements. In game theory terms, he changed the payoffs so that betrayal stopped paying.

David Hume saw the other side in his Treatise of Human Nature (1739). Two neighbours have corn that ripens at different times. Each would gain by helping the other harvest, but the one whose corn ripens second has every reason to skip the favour once she has been helped. Hume’s point was that people do keep such bargains, because they expect to deal with each other again and a reputation for breaking your word costs more than any single betrayal gains.

Jean-Jacques Rousseau offered a close cousin in 'the stag hunt'. A group of hunters can bring down a stag only if all of them hold their positions, but any one of them can slip away and catch a hare instead. The stag is the better meal and the hare is the safer one, and the question is whether you trust the others to stay put.

Much later, the political scientist Robert Axelrod ran computer tournaments in the early 1980s to see which strategy won when the dilemma was played again and again. The winner was the simplest entry, “tit for tat”: cooperate first, then copy whatever your opponent did last time. It was generous enough to build trust and firm enough to punish betrayal. Axelrod’s conclusion, set out in The Evolution of Cooperation (1984), was that cooperation becomes rational once the players expect to meet again.

Now bring this idea to life with an imaginary two talent academies in a certain locality…

Imagine there is a nine-year-old from your catchment with signs of significant ability. You would rather wait until she is twelve or thirteen, when you can see how she grows, how she copes and whether she still loves the game post maturation. But if you wait and your rival doesn’t, the best child in the area is gone. So you sign at nine. Your rival, seeing that, drops to now starts looking for the best eight year olds. Nobody chose this. Each academy made a sensible decision on its own, and the sum of those decisions is a market where children are scouted before they have left nursery and still believe in Santa.

The ratchet only turns one way

Take a club with twenty children in each age group. Recruit three years earlier and you carry sixty extra children on your books every season, with the coaching, travel, welfare and parent management that come with them. You pay that bill every year, and what you buy is a coin-flip made with worse information.

Early selection predicts poorly because young children develop at wildly different speeds. The relative age effect is well documented across sport: children born in the first months of the selection year are overrepresented in academies, simply because they are bigger and more mature on the day they are picked. Many of them are good. Some are just early. The late developer who would have been brilliant at sixteen sits on the other side of the fence, told at ten that he isn’t good enough. Figures of around one in a hundred or lower are often quoted for how many boys signed at under-nine level in English academies go on to make a living from the game, and nobody can say those are the right ones.

Where the cost lands

Clubs carry some of it. Children (and their parents) carry most of it. A child released at twelve, after three years of an identity built around being “an academy player”, has lost something real, and no scouting report records it. Add the families driving three nights a week and the schools quietly adjusting, and you can see why this “rational” behaviour feels so wrong to anyone standing outside it.

Two ways out, both borrowed from the philosophers

Hobbes’s route is the sovereign: a league or governing body that sets an age floor and polices it, so that approaching an eight-year-old carries a cost. English football’s Elite Player Performance Plan (2012) pulled this lever with fixed compensation for youth players and tiered academy categories. The results have been mixed and the pressure to recruit early has not gone away, but it shows the lever exists. By the same measure Ross reminded me of the time when I was at England Rugby we developed a consensus statement around talent development that enabled us to make the decision that the entry to the talent pathway and rugby academies couldn't happen until fourteen.

If you can't mandate it through regulation then Hume’s and Axelrod’s route is communication, education and repetition. Academies, clubs, regions, coaches are brought together regularly and the same message is provided and repeated. The message needs to be evidence based so that it hits the head, it also has to have strong poral and ethical grounding so that it appeals to the heart.

Whatever , you can also make your own position stronger. Build a proper late-entry route at fourteen or fifteen, which costs far less than another under-nine squad and gives you access to talent your rivals have already dismissed. Use bio-banding (grouping children by maturity rather than birth date) in your assessment, so you stop mistaking early growth for ability. And if you do recruit early, make your release process good, with a decent exit and a route back into the game.

The suspects in the original story never get a second round. You do, which is the best argument for making the first decision.
