When the rules reward the wrong thing

A rule that quietly did the opposite

A league wants to help its weakest clubs catch up. So it hands the worst-finishing team the first pick of next year’s young players. Generous, fair, well-meant. And by the final weeks of a lost season, you can watch that same club rest its best players and slide on purpose — because losing now buys a better pick later. The rule meant to lift the weak ended up paying clubs to fail.

That gap — between what a rule was meant to do and what it actually rewards — has a name: a perverse incentive. A rule, built to do X, ends up rewarding an unwanted behaviour Y. You met one version last lesson with tanking. This lesson shows it’s a pattern, not a one-off. Once you can spot it, you stop asking “why are these people behaving badly?” and start asking the sharper question: what is this rule actually paying for?

Tanking: paying clubs to lose

Start with the case you already know, because it’s the cleanest. The reverse-order draft (worst team picks first) was designed to redistribute talent to weak clubs. Intended: weak teams get stronger, the league stays balanced. Rewarded: a club with nothing left to play for now earns a better future by losing more games today.

Nobody wrote “lose on purpose” into the rule. The rule just can’t tell a club that is genuinely weak from one choosing to look weak — and it attaches a prize to the bottom of the table. People follow the prize. That is the whole shape of a perverse incentive in one example: the reward sits next to the behaviour the designer wanted, and the wrong behaviour collects it.

Doping: an arms race nobody can leave

Now a harder one. The reward for winning at the top of a sport is enormous — money, fame, a career. So large that some athletes take banned substances to gain an edge. Doping here just means using a prohibited drug or method to perform better than your real level allows.

Watch the trap close. Suppose a few competitors dope and gain a small edge. An honest athlete now faces a brutal choice: stay clean and lose to cheats, or dope to keep up. The rational move, purely on the incentive, is to dope — not because they’re wicked, but because the reward for winning is so big and the cost of falling behind so steep. That is an arms race: once one side escalates, everyone feels forced to escalate just to hold their place.

The point isn’t that athletes who dope are simply bad people. Some are; that’s not the system’s lesson. The lesson is that a reward this large, with weak detection, manufactures the pressure. Make winning worth almost anything, and you’ve quietly made cheating worth the risk for many. Fix only the person and a new one fills the gap. Shrink the reward-for-cheating — better testing, real bans — and you change the sum everyone is doing.

Match-fixing: a reward from outside the game

The third case is sneakier, because the incentive doesn’t come from the sport at all. It comes from the betting market.

When you can bet on a specific outcome — not just who wins, but small things, like how many fouls happen in a half, or whether a player gets a booking — you create a reward for arranging that outcome. Match-fixing is exactly that: someone makes the result, or a piece of it, happen on purpose because money outside the game pays for it.

Here’s why the small markets matter. Asking a team to lose a final is a huge, visible ask. But asking one player to give away a single needless foul at a set minute? Tiny. Almost invisible. Yet a gambler who knew it was coming could stake a fortune on it. The narrower and odder the thing you can bet on, the cheaper it is to fix and the harder it is to spot. The incentive was created the moment the market opened on that small event — long before anyone acted on it. The game didn’t bend from within; an outside reward reached in and bent it.

Financial fair play: the rule that locks in the strong

The last case is the subtlest, because the rule looks like the cure for an incentive problem and quietly becomes one itself.

Clubs were spending far beyond their income, chasing success and risking collapse. So leagues brought in financial-fair-play rules — call them FFP: a club may only spend roughly what it earns. Sensible on its face. Live within your means.

But trace what “what it earns” rewards. A club’s revenue depends heavily on how big it already is — its fanbase, its history, its prize money from past wins. So the giants, with huge revenue, can keep spending huge amounts and stay inside the rule. A smaller club that wants to spend its way up the table — to buy the success that would grow its revenue — is told it can’t, because its revenue is still small. The rule ties future spending to past size. Intended: stop reckless overspending. Rewarded, in effect: the clubs that are already big, by freezing the ladder beneath them.

So a rule sold as fairness can entrench the incumbents — the ones already on top. Not through anyone cheating. Just by tying permission-to-spend to a number the strong already have and the weak don’t.

On the whole

Four cases, one shape. In every one, the honest question is not “who are the bad people?” but “what is this rule paying for?” Tanking pays for losing. A vast winner’s prize pays for cheating. A betting market on a tiny event pays for fixing it. A spend-what-you-earn rule pays for already being big. The behaviour follows the reward, and the reward was built — usually by someone with good intentions — into the rule.

This is not a sports quirk. Wherever a rule sets a reward, behaviour drifts toward whatever sits closest to that reward, intended or not. The tax break meant to help, the metric meant to measure, the bonus meant to motivate — each can quietly pay for something its designer never wanted. You are inside many such systems, nudged by incentives you may never have named. Seeing them clearly is the start of designing them — or living in them — a little more wisely.
