Accountability, and what makes it work

External accountability is among the more effective behaviour change tools available, and the popular version of it — announcing intentions — is among the least effective forms.

Announcing does not help

The finding that surprises people.

Several studies have found that publicly stating an intention can reduce subsequent effort toward it, with the proposed mechanism being that the social recognition of the announcement provides some of the satisfaction the achievement would have.

The evidence is contested and the effect is not large, and there is no good evidence that announcing helps.

Which means the common practice of declaring a goal to everyone is, at best, neutral.

What does work

Specific reporting to a specific person. Not an announcement but a recurring obligation to report.

The mechanism is straightforward: an approaching moment at which you will have to say what you did produces action in the days before.

Weekly is generally about right. Daily becomes noise; monthly is too distant to influence a given day.

Doing it alongside someone. Body doubling, training partners, writing groups, co-working.

Effects here are reasonably well documented in the exercise adherence literature, where social support is among the stronger predictors of continuation.

The mechanism includes obligation, and it also includes the simple removal of the decision — if someone is expecting you at seven, the decision was made yesterday.

Financial commitment devices. Money at stake, forfeited if the commitment is not met.

Studies of commitment contracts have found meaningful effects on outcomes including smoking cessation and exercise adherence.

The effect appears stronger when the forfeited money goes somewhere the person dislikes rather than to charity, which is telling.

Structural commitment. Paying in advance, booking a course, entering an event.

Less about willpower than about having removed the option, which is generally the more reliable design.

Why it works

Several mechanisms, and it is worth knowing which one you are using.

Immediacy. Most worthwhile behaviours have distant rewards and immediate costs, which is exactly the shape people handle worst.

Accountability supplies an immediate consequence, which corrects the imbalance.

Consistency. Having stated a commitment to someone specific, people are more likely to follow through, which is a well-documented influence effect.

Removing the decision. A fixed arrangement with another person is not renegotiated daily.

Designing it

Choose the right person. Someone who will actually ask, and who is not so close that they will let it slide.

A partner or close friend is frequently the worst choice for exactly this reason. A peer with a parallel commitment is generally the best.

Make it reciprocal. Mutual arrangements last longer than one-directional ones, because both parties have a reason to maintain them.

Report the behaviour, not the outcome. "Did you do the four sessions" is answerable and within your control. "How is it going" invites narrative.

Fix the time. An arrangement to check in when convenient does not survive a busy fortnight.

Keep it short. Five minutes. Long accountability conversations become social calls, which is pleasant and is not the function.

Where it fails

When the reporting becomes performance. If the person begins presenting a version rather than reporting, the arrangement has inverted.

When the stakes are wrong. Too small and it is ignored; too large and it produces anxiety and avoidance of the whole arrangement.

When the goal was wrong. Accountability enforces a commitment; it does not evaluate whether the commitment was sensible.

Someone held accountable to an unsuitable plan is being helped to persist at something they should stop.

Which means any recurring arrangement should include an occasional question about whether this is still the right thing, rather than only whether it was done.

The self-accountability version

Weaker and available.

A written record reviewed weekly provides some of the effect, particularly if the review is scheduled rather than optional.

It is reliably less effective than another person, which is worth knowing before choosing it on the grounds of not wanting to bother anyone.

Most people asked to be someone's accountability partner say yes, for the same reasons discussed elsewhere about how willing people are to help.
