User-written goal, shown back
Ask users to write, in one sentence, what they want to achieve, then show it back at useful moments: on low-motivation days, at the next milestone. Writing makes the commitment active and gives users a record of their own intent; when the goal is reached, prompt the next one.
Plain label: goal in the user's own wordsAlso known as: written commitment, active commitment, goal setting, why are you here?
How it works
A commitment people make actively, especially in writing, shapes their self-image more than one they merely accept: the written statement is evidence they cannot easily deny and a document others can see. Effort and free choice strengthen it further. The record has to stay the user's own: editable, easy to archive and never used against them when they leave.
In the book. Active, written commitments change self-image more than passive ones, and even copying a statement counts (Ch.3, pp.58-62). INF-T-CC-09 (Influence Ch.3, p.58)
In a product [S]. The user's own goal, in their words, shown back when it helps; editable, and never used to block leaving.
Evidence Evidence grade B. Moderate evidence: solid studies with some limits.. Active and written commitments have moderate support; product tests are mostly internal.
What the research says
The book describes written commitments as harder to deny and easier to make public; a direct-sales company had sellers write their goals down and set a new one each time one was met (company practice).
Influence Ch.3, pp.58-61
In a classic line-judging study, public written commitments were the most resistant to change, private written ones came next, and no commitment was weakest.
Influence Ch.3, pp.62-63 (Deutsch & Gerard), 1955
How to build it
- Mobile
- In onboarding, ask "What would make the next month a success for you? One sentence is enough." and show the answer on the home screen on days the user opens the app but does not act.
- B2B
- Have the champion write the team's success criteria during setup, and show them on the admin dashboard and at renewal.
- Web
- When a written goal is reached, celebrate it in the user's own words and prompt the next goal.
What can go wrong
- Quoting the goal back in the cancel flow ("you promised yourself").
- No way to edit or archive a goal that no longer fits.
- Making the goal public without asking.
Pairs well with
- Pairs with in-t-cc-01: ask for the goal after the first win.
- Pairs with in-t-cc-12 when the user wants an audience.

What we don’t claim
- Left Brain and Right Brain are a metaphor for extrinsic and intrinsic motivation, not a claim about neuroscience.Actionable Gamification Ch.13, pp.342-343
