Nobody checks whether you did it? How to hold yourself accountable for a habit

To hold yourself accountable, make the goal something you can check with a number, let someone else see the result, and decide in advance what a miss costs. A promise to yourself fails because it is easy to renegotiate. Research backs the first two parts best, and the third is promising but mixed.

Here is how a goal with no one checking it slips away, without anyone deciding to drop it.

1. tell nobody

   Day 1

   You decide to write every evening. You tell nobody, because it is your own project, and that feels like the grown-up way to do it.

2. counts double

   Day 4

   You write on Monday and Tuesday. On Wednesday you are tired, and you decide Thursday will count double. Nobody knows the difference, and neither does the notebook.

3. 

   Day 9

   The desk is set up and the headphones are on. Then there is one thing to look up first, and the evening goes there.

4. three, maybe four

   Day 14

   Count the fortnight and you cannot say how many evenings you wrote. Three, maybe four. Without a number, "pretty good" and "not really" are both true.

5. nothing ever checked it

   Day 21

   The goal is still yours and has never been broken, because nothing ever checked it. It has just stopped appearing anywhere.

Why a promise to yourself is easy to bend

Accountability needs someone or something that notices a miss and does something about it. When you are both the person who promises and the person who checks, every check can be argued down: today was unusual, tomorrow will be better, three out of four is basically four.

There is some evidence for the optimism part. Daniel Acland and Matthew Levy ran a gym-attendance experiment and asked participants to predict how often they would go once the study's incentives were over. They guessed far higher than what they did. My reading, not theirs: a plan made on a good day is judged by the version of you who feels good, and that version does not turn up on Wednesday evening.

What helps: checking, a consequence, other people

The research below covers three different things: watching your own progress, attaching a consequence to a miss, and letting someone else see the result.

Checking your own progress

A team led by Benjamin Harkin pooled 138 randomised studies with nearly 20,000 participants in total. The studies tested interventions that make people check their progress toward a goal more often. On average, those interventions improved goal attainment by about 0.4 of a standard deviation, a modest but real gain. Two features went with bigger gains: results that were shared with other people, and progress that was recorded in a physical form, such as writing it down.

The goals in those studies were varied, and the review is about interventions that prompt monitoring, not about any one method. But it gives two practical hints: write the result down, and let someone see it.

A consequence you set in advance

Economists call a choice that makes a later slip more costly a commitment device. The idea was formalised in the 1950s, including by the economist Robert Strotz, and the best-known illustration is older: Odysseus had himself tied to the mast so he could hear the Sirens without steering towards them. Gharad Bryan, Dean Karlan and Scott Nelson reviewed the field evidence and distinguish hard commitments, which carry a material cost, from soft ones, which work through how we feel about breaking our word.

Two field studies show both the promise and the catch.

• A company gym. Heather Royer, Mark Stehr and Justin Sydnor studied workers at a large company. They were given an incentive to use the gym that ran for a month, and once it ended, little of the change remained. At that point some workers could sign a commitment contract that they would fund themselves. There was demand for it, and in that group the change was still visible years later.
• A smoking-cessation trial. Scott Halpern and colleagues enrolled 2,538 people, employees of one company along with family members and friends, and assigned them to four programmes. Two asked for a refundable deposit that came back with a reward for those who quit, and two offered only a reward. When a deposit programme was the assignment, 13.7% accepted it. For a reward programme, 90.0% did. Overall, the reward programmes had more people who stayed off cigarettes through six months, 15.7% against 10.2%. Among the estimated 13.7% who would have accepted either kind, the deposit programmes did better, by 13.2 percentage points, with a wide margin of error (3.1 to 22.8).

Put together, a consequence seems to help the people who sign up for one, and most people won't. Those studies used real financial deposits, and I am not suggesting that. They also don't tell us how large a consequence needs to be. A cost you can actually live with, delivered every time, is the version worth trying.

Other people who see the result

Besides the finding above that reported or public results worked better, one trial put the social side into a game. Mitesh Patel and colleagues gave 200 adults from 94 families step goals and daily feedback. For the families in one group, they also ran a game with points and levels that was meant to make relatives more answerable to one another. Over the 12 weeks of the game, that group reached the step goal on 53% of participant-days, against 32% in the comparison group. After the game ended, the gap shrank, 44% against 33%, but it did not disappear.

That trial combined points, levels and family support, so it can't say which part did the work. The participants were adults from one long-running heart-study cohort. It does suggest that a points game with people around you can beat tracking alone for a while, and that the effect fades once the game stops.

How to hold yourself accountable in 5 steps

The steps below are my own plan, built on the studies above. Each one says how far the evidence goes.

1. Make the goal something a stranger could check. "Get fit" can't be checked. "Run three times this week" can. Choose a number for one week at a time. This is my step: the monitoring studies need something to monitor, and a vague goal gives you nothing to count.
2. Record each result where you can see it. A calendar on the wall, a notebook or a spreadsheet will do. Physical recording is one of the things that went with larger effects in the Harkin review, though that review does not compare a wall calendar with a spreadsheet.
3. Let someone else see the result. Reported and public results did better in the review, and there is more than one way to do it: hang the calendar where the people you live with walk past it, post a weekly "done" or "missed" in a group chat, or leave the sheet on the table on Friday. Pick the version you won't dodge. Choosing a way that is read, not discussed, is my addition, because a lecture is a good reason to hide a miss.
4. Decide the consequence before the week starts. Write it as an if-then line: "If I miss a run, I do the washing-up for the flat on Sunday." Keep it small enough that you will really do it. Then do it every time, because a consequence you skip once teaches you it is optional. That last point is my reasoning, not a finding. The commitment-device research is why I include a consequence at all.
5. Review once a week and change the plan, not the rule. If you missed the target twice, ask whether the target was too big. Shrinking it is usually better than dropping the consequence. My post on starting tiny is about sizing it. The weekly review is my own step.

Examples: a vague promise next to an accountable one

Goal	The vague promise	Something you can check	Who sees it	If I miss
Running	"I'll run more"	Three runs of 20 minutes this week	A weekly "done" or "missed" in a group chat	I do the washing-up for the flat
Writing	"I'll write every day"	Five evenings of 30 minutes	A note on the fridge door	The next morning, I write before I look at my phone
Studying	"I'll revise properly"	Three sessions of 25 minutes by Friday	The tick sheet left on the kitchen table on Friday	I give up one episode of a show that evening
Reading	"I'll read more"	20 pages a day, five days	A tally on the book's last page	The page count carries over to the weekend
Language	"I'll practise Spanish"	Four lessons this week	A voice note to a sibling on Sunday	I do the lesson in the morning before coffee
Stretching	"I'll be more flexible"	Ten minutes, four mornings	A mark on the bathroom mirror	An extra five minutes the next day
Lights out	"I'll sleep earlier"	Phone off by 23:00 on five nights	A friend asks on Sunday	Phone charges in another room next night
Cooking	"I'll eat at home"	Four home-cooked dinners	A photo to my sister	The next takeaway has to wait a week

When it doesn't work

• When you won't sign up for it. In the smoking trial, only about one in seven accepted a deposit programme, and the authors of the gym-attendance study suggest that few people choose such tools partly because they misjudge their own future behaviour. A plan that needs the strict version only works for people who start it.
• When the consequence is skipped. A penalty you waive once teaches that it is optional. That is my observation, not a finding.
• When the person watching becomes a judge. If you start hiding misses to avoid a lecture, the check has stopped working. I found no study on this, so it is my judgment.
• When it is about food, weight or your body. Penalties and guilt around eating can do harm. If you have a history of disordered eating, or you notice that a penalty makes you anxious, drop it and talk to a doctor or a therapist.
• When the effect fades. In the family game, the benefit shrank once it ended, and in the workplace study the short incentive on its own left little behind once it ended. Expect to adjust the plan, not set it once.
• When the goal is not yours. If someone else set it, accountability turns into obedience. Ask whether you want it before you build a system around it.
• When the evidence is thin. I found no study of holding yourself accountable as such. The studies are about gym use, smoking and steps, with workers, volunteers and families, and the steps above borrow from them. Treat this as a reasonable plan to test, not a proven recipe.
• When it isn't a habit problem. If everything has felt flat and hard to start for weeks, not only one habit, it may be depression, burnout or something else that accountability cannot fix. Talk to a doctor or a therapist.

How I do it myself

In Habit Bank every habit carries two numbers, a Habit value for doing it and a Penalty value for missing it. If I haven't checked a habit off by midnight, the penalty is counted, so I never have to be the one who enforces it. The points are virtual: the app says so on the screen and does not pay out or fund anything. I have not seen a controlled test that isolates virtual penalties, so that part is my experience, not evidence.

I respond to losing things. I've stopped pretending otherwise.
