A motorcyclist runs a guy off the road doing triple digits and the case gets pled down to a non-criminal infraction. A travel team kid mouths off to a coach, misses two practices, and starts at shortstop anyway because the team needs the bat. Different scales, same mistake. Somewhere along the way we decided that consequences are something to be deployed sparingly and dramatically — saved up for the worst offenders, the worst games — rather than applied consistently to ordinary ones. That's backwards, and there's real research behind why.
What the criminologists actually found
Criminologists have spent decades trying to figure out what actually deters bad behavior, and the answer that keeps surfacing isn't the one most people assume. It isn't severity. It's certainty.
The idea traces back to Cesare Beccaria, the 18th-century Italian jurist who argued that the deterrent power of punishment comes from its certainty and swiftness, not its harshness. Modern criminology has largely vindicated him. The criminologist Daniel Nagin, who's spent his career studying deterrence, has found a consistent pattern across decades of research: increasing the certainty of being caught has a real, measurable deterrent effect, while increasing the severity of punishment for those who are caught has a weak effect at best — and sometimes none.
The intuition behind this isn't complicated once you sit with it. A person deciding whether to run a red light, skip a court date, or cut a corner at work isn't doing actuarial math on a twenty-year sentence they assume they'll never face. They're doing a much simpler calculation: will anyone notice? A small, near-certain consequence beats a large, unlikely one every time, because human beings discount low-probability events almost to zero. We're wired to ignore the lightning strike and worry about the daily commute.
The system we've actually built
And yet the system we've built — in courtrooms and on ballfields alike — runs on the opposite logic. We let things slide constantly: declined charges, deferred prosecutions, the quiet word instead of the bench, the "I'll let it go this once" that becomes every time. Then, periodically, when something finally crosses a threshold of outrage, we reach for the maximum. We go from doing nothing to doing everything, skipping the entire middle where actual deterrence lives.
This isn't an argument for harshness. It's the opposite. The honest version of "tough on crime" isn't "throw the book at people" — it's "make consequences reliable." A prosecutor's office that charges consistently and proportionately, every time, for every comparable case, will do more to change behavior in a community than one that's lenient nine times out of ten and then makes an example of the tenth. The first approach teaches people that actions have predictable consequences. The second teaches people to play the odds — and the odds, historically, favor them.
There's a justice argument buried in here too, separate from the deterrence one. Reserving real consequences for rare, severe cases means you're usually not holding people accountable for ordinary intentional misconduct — the corner-cutting, the no-call-no-show, the talking back — and that's not mercy. It's neglect dressed up as leniency. Treating every instance of culpable conduct seriously, even mildly, is actually the more honest and more just system, because it matches the response to what the person actually did, rather than saving up moral judgment for whatever happens to make the news.
Same logic, smaller stakes
I see the identical dynamic from the other end of the bench, coaching kids. A player who doesn't pay attention in the field, or talks back, or blows off practice isn't usually doing something that warrants a benching for the season — that response would be disproportionate, and kids (like adults) sense disproportion and tune it out as unfair. But if the response to repeated, ordinary lapses is "I'll let it slide because we need him in the lineup," you've taught him something true and durable: that effort and attitude are negotiable as long as the talent is real. That lesson outlives the season.
The better move is the unglamorous one — a missed inning, a lap, sitting the start, every time, immediately, without drama. Small, certain, boring. It's not satisfying in the moment. It also actually works, for the same reason it works in a courtroom: people — kids and adults alike — respond far more to "this always happens" than to "this might really happen to me eventually, and if it does it'll be bad."
The common thread
Leniency that's dressed up as kindness usually isn't kind — to the offender, to the next victim, to the rest of the team watching how the coach handles it. Holding someone accountable doesn't require throwing the book at them. It just requires actually doing it, consistently, every time the line gets crossed — not saving your nerve for the cases that make the news, or the kid you're tired of benching.
Certainty over severity. It's better criminology, and it's better parenting.
