Do family phone contracts actually work?

Some clauses do and most do not. In fourteen households we followed for a year, five agreements survived, and the common element was a rule about where the phone is overnight — a physical, checkable rule rather than a behavioural one. Daily time limits, the most popular clause, had the worst survival rate: ten of eleven lapsed within four months.

Where should a teenager's phone be at night?

Out of the bedroom, in a named place, on a charger that lives there. The households where this held did not treat it as a punishment or a trust issue; they treated it as where the phone lives, the same way keys live in a bowl. The rule survives because it is a single observable fact rather than a running judgement about use.

Why do screen time limits fail?

Because they require continuous enforcement by an adult who is also doing everything else. A time limit turns every evening into a potential negotiation, and negotiation costs are what kill household rules. Rules that resolve to a yes-or-no fact — the phone is in the kitchen or it is not — cost nothing to enforce.

Should you renegotiate a phone agreement as a teenager gets older?

Every surviving agreement in this group had been renegotiated at least once, and in every case the teenager raised it. The families read that as the system working. An agreement that cannot be changed gets broken instead, which is the same outcome with worse information.

The Phone Contract That Held

Most family phone agreements are written in the week a phone is bought and abandoned within a term. We asked fourteen households what survived, and one clause showed up in every arrangement still standing after a year.

Phone agreements still in force after a year

100%

Of surviving agreements that specified where the phone sleeps

10 of 11

Daily time limits that had lapsed within four months

I spent eight years teaching middle school, which means I have confiscated a phone, sat through the meeting about it, and written the email home the same night. I came into this reporting expecting the finding to be that phone contracts do not work.

Five of fourteen were still in force a year later, which is a higher survival rate than I would have predicted for any household rule, and the five have something in common that the nine do not.

The clause that survived

Every agreement still working specified where the phone sleeps.

Not how long it can be used. Not which apps. Where it physically is between roughly 9 p.m. and morning: a kitchen drawer, a charging station on a landing, a basket on top of the fridge. In three of the five households the parents’ phones go in the same place, which the teenagers in those households raised, unprompted, as the reason the rule was tolerable.

The rule survives because checking it costs nothing. It is one observable fact. Nobody has to form a judgement about whether ninety minutes of a group chat is different from ninety minutes of homework, because the question never arises.

The clause that failed

Eleven of the fourteen set a daily time limit. Ten had lapsed inside four months.

They fail for a structural reason rather than a moral one: a time limit has to be enforced continuously, by an adult, in the evening, which is exactly when that adult is cooking, working or asleep. Every evening becomes a possible negotiation, and negotiations are expensive. Households do not abandon time limits because they stop believing in them. They abandon them because the enforcement cost is paid nightly and the benefit is diffuse.

One mother put it more precisely than I could: “I was spending forty minutes a day policing two hours.”

What the teenagers said

I interviewed nine of the teenagers separately. Their assessment of which rules were fair was remarkably close to the survival data.

They did not object to the overnight rule. Several said they preferred it, and two described sleeping better in terms that were unmistakably relieved. What they objected to, uniformly, was rules that changed without discussion — a limit tightened after a bad report card, an app removed following an argument. Every one of them could name an instance. Every one of them described it as the moment they stopped treating the agreement as an agreement.

The five surviving arrangements had all been renegotiated at least once, and in all five the teenager raised it. The parents in those households described the renegotiation as annoying and necessary. The parents in the collapsed households mostly described their agreement in the past tense without being able to say when it had ended.

What to write down

If I were writing one of these now — and I will be, in about eighteen months, for my second child — I would write three lines. (The equivalent three lines for schoolwork are in The AI Homework Conversation, and the school’s side of it is in The Phone-Free School Year.)

Where the phone sleeps. Who else it applies to. When we will look at this again.

Everything else, on this evidence, is a rule you are going to stop enforcing in February.
