Making a Promise That Survives the Moment You Want to Break It

What each one is actually for

Secure Functioning

Secure Functioning is the name Stan Tatkin's PACT model (Psychobiological Approach to Couple Therapy) gives to an explicit agreement two partners make: to treat the relationship itself — what Tatkin calls the 'couple bubble' — as a shared thing you both actively protect, rather than assuming closeness will just happen because you love each other. In practice this means partners write or say out loud specific agreements: how you handle a disagreement in front of other people, what happens every time one of you leaves or returns home, what one of you says when the other looks stressed at 11 p.m. These aren't vague values, they're concrete, repeatable moves you both agreed to in a calm moment, meant to run automatically later, in the moments neither of you would naturally think clearly enough to invent something kind on the spot.

Ulysses Contracts

A Ulysses Contract takes its name from Ulysses ordering his crew to bind him to the ship's mast before they sailed past the Sirens, because he knew that once he heard their song he would beg to be let free, and he wanted the earlier, clear-headed version of himself to win. The practice generalizes that: you use a binding external constraint, put in place while you're thinking clearly, so a later, foreseeable moment of weaker willpower can't undo the decision. Concretely — you give your credit card to a friend before a trip you know will tempt you to overspend, you have a financial planner auto-withdraw savings before you ever see the paycheck, you tell a specific friend your exact relapse-risk situation and ask them to call you at a set time. The binding has to actually cost you something, or be genuinely hard to undo, or the later self will just talk its way out of it too.

What you get out of pairing them

A couple relying on good intentions alone is betting that the exhausted, defensive version of either partner will handle an 11 p.m. flashpoint as well as the rested, reasonable version would have — a bet Secure Functioning refuses to make, since the agreement was reached earlier, while both people could actually think. Someone relying on willpower alone at the exact moment of temptation is making the identical bet on themselves, and a Ulysses Contract refuses it the same way: by making the earlier, clearer decision hard to walk back later. Neither practice is really about being a better person in the moment. Both quietly remove the moment's power to decide anything at all.

What Secure Functioning rests on

• Attunement requires active monitoring not good intentions clinical practice
  Staying attuned to a partner's internal state requires ongoing structured attention rather than goodwill alone because connection erodes by default without it.
• Explicit commitment changes daily priority weighting clinical practice
  Explicitly and mutually committing to protect the relationship above other priorities changes how partners weigh choices during ordinary daily conflict.
• Rituals of connection reduce reliance on spontaneous attunement practitioner report
  Building repeatable rituals of connection reduces dependence on spontaneously noticing a partner's needs in the moment.

What Ulysses Contracts rests on

• Implementation intention closes intention action gap randomised trials
  Pre-committing to a specific situational cue paired with a specific response lets the behavior fire automatically when the cue occurs, without depending on in-the-moment willpower.
• Removing future optionality protects present intent randomised trials
  Binding a future choice through an external cost or barrier prevents a later moment of weaker willpower from overriding a decision made while thinking clearly.
• Temporal discounting erodes willpower randomised trials
  People systematically undervalue future consequences relative to immediate temptation, which is exactly the bias a binding precommitment is designed to neutralize.

Where they actually meet

Strip away that one is about two people and the other is about one person facing their own future self, and the same move shows up in both: a decision made in a calm, clear-headed state is deliberately locked in, ahead of time, so a later moment — of stress, temptation, exhaustion, or distraction — cannot quietly override it. Tatkin's couples write down what happens when one partner is stressed at 11 p.m. for the same reason Ulysses had himself bound to the mast: neither the exhausted partner nor the tempted sailor is a reliable narrator of what the situation calls for, and both practices route around that by not asking them to decide anything in the moment at all.

The principle underneath both

An implementation intention — deciding, in advance, that when a specific situation happens (a cue), you will do a specific, already-chosen thing (a response) — lets the response fire without needing a fresh decision under pressure. Research on implementation intentions consistently finds they close the gap between intending to do something and actually doing it, because the decision has already been made by the time the moment arrives — there's nothing left to decide, only something to execute. A PACT couple's agreed-upon door-greeting ritual is an implementation intention with a relationship as the target. A Ulysses Contract is an implementation intention with an external enforcement mechanism bolted on, for situations where willpower alone wouldn't be enough to make you follow through even with the plan already made.

What that makes the real goal

Both practices bet that timing beats willpower. The decision about what happens at 11 p.m., or what happens once the ship passes the island, doesn't get made at 11 p.m. or on the water — it already happened, earlier, while the person deciding was in a state actually capable of judging well. What's being managed here isn't character. It's when, exactly, a decision gets made.

Other practices that serve the same goal

Once the objective is named as moving a decision to a better moment and making it stick, other practices built for exactly that come with their own evidence. Mental contrasting combined with implementation intentions — a technique called WOOP, short for Wish, Outcome, Obstacle, Plan — has randomized trial support for helping people follow through on goals by pre-deciding responses to specific obstacles, which is a general-purpose version of what both PACT and Ulysses Contracts do in their own domains. Commitment devices in behavioral economics — automatic retirement-savings enrollment, apps that lock your phone during work hours, betting real money on hitting a fitness goal — are Ulysses Contracts with financial or technological teeth instead of a friend holding your credit card, and several have been tested in field experiments. On the relationship side, the fixed daily check-in ritual that Gottman's research separately identifies serves the same function as a PACT ritual: a predetermined cue-response pair that doesn't depend on either partner noticing, in the moment, that connection is needed.

A tradition that already does this

Implementation-intention research itself, going back to psychologist Peter Gollwitzer's work in the 1990s, already generalized this exact move across dozens of unrelated domains — exercise adherence, medication compliance, exam preparation — well before either PACT or the language of Ulysses Contracts applied it specifically to couples or to self-control. Both practices in this pairing are, in a real sense, later applications of a principle that already had its own independent research lineage.

Turning a Couple's Agreement Into a Real Precommitment

A common way a relationship deteriorates is one partner withdrawing under stress — going quiet, avoiding the other, not out of malice but because in the moment, withdrawing feels easier than reaching out. Treat a PACT-style agreement as a precommitment aimed at exactly that future self: while calm, agree explicitly that stress does not excuse silence — that the stressed partner will say a specific short phrase ('I'm overwhelmed, I need twenty minutes, I'm not leaving') instead of just going quiet. Write it down, or say it out loud to each other as a real commitment, the way you'd tell a friend to call and check on you. The binding element that makes this more than a nice idea is that you both agreed the silent version is now off the table — the future stressed self doesn't get to relitigate whether to say something, only which of the pre-agreed words to use.

Giving a Couple's Ritual the Teeth of a Ulysses Contract

Couples agree to rituals of connection all the time and then quietly stop doing them within a few weeks, the same way New Year's resolutions fade, because good intentions alone rarely survive a busy Tuesday. Borrow the external-stakes structure of a Ulysses Contract to protect a ritual you've already agreed on: tell a specific friend or couples counselor what the ritual is and ask them to check in with both of you about it in two weeks, the same way you'd hand a credit card to someone else before a tempting trip. The point isn't distrust of your partner — it's recognizing that a private agreement between two tired people, with no outside accountability at all, is exactly the kind of commitment research on willpower predicts will erode fastest.

The night one of you comes home already shut down

One partner walks in after a brutal day, drops their bag, and heads straight for the other room without a word — the exact moment neither of you would trust either person to handle well from scratch. But three weeks ago, calm and not stressed about anything, you agreed on this: whoever comes home like that says one sentence — 'rough day, give me fifteen minutes, then I'm all yours' — instead of disappearing silently, and the other partner's job is to say 'okay' and mean it, no follow-up questions for those fifteen minutes. Tonight, the stressed partner says the sentence, feeling almost silly saying it out loud, and the other partner just says okay and goes back to what they were doing. Fifteen minutes later, the stressed partner comes back out, actually present, instead of the silent withdrawal turning into an entire evening of distance neither of you chose on purpose.

When this is worth reaching for

The actual problem is follow-through, not an absence of love or good intentions — couples who genuinely want to show up for each other but keep getting undone by exhaustion or the general unreliability of trying to be your best self at the exact moment you're least equipped for it. It also fits someone building a personal habit alongside their relationship, since the same binding-commitment muscle transfers between the two.

Where this does not apply

If a relationship's core problem is a fundamental mismatch in values, ongoing dishonesty, or one partner unwilling to make agreements in good faith at all, no amount of structured commitment devices will produce trust that was never there to begin with — a Ulysses Contract only works if the person who set it up actually wants the outcome and just needs help getting past a predictable moment of weakness, not if they're being coerced into an agreement they don't believe in. Treating every disagreement as something to pre-script in advance can also flatten a relationship into a checklist and crowd out the spontaneous responsiveness that genuinely matters too — rituals should cover the predictable failure points, not replace ordinary, present attention entirely.

What the evidence does and does not support

Implementation intentions have some of the strongest evidence in behavioral science, with dozens of randomized trials across health, academic, and habit domains showing they close the gap between intending something and doing it. PACT's specific couple-bubble framework rests mostly on clinical case experience and Tatkin's own synthesis of attachment and neuroscience research, rather than randomized trials of the PACT model itself. Ulysses Contracts as a general self-control strategy have field-experiment support in areas like savings and health behavior. What is untested is this exact pairing — using an external-stakes commitment device to enforce a couple's connection ritual — though the underlying implementation-intention mechanism each half relies on is independently well supported.
