How to utilise this in your designs

When someone turns on a protective setting, you could let them write a note to their future self, shown if they try to turn it off, so undoing it clashes with their own words.

Onboarding for a gambling block. "A note for future you" explains users can write a reminder of why they blocked gambling; tapping "Get started" opens a text field whose note is shown if they try to unblock.

Example from

Monzo

Try opening the front camera when someone tries to break a limit they set themselves, so they have to face the dissonance between their goal and what they're doing.

Settings screen. On the "Intervention" options, tapping "Mirror" opens a detail card tagged "one sec pro", explaining "Look in your own eyes and tell yourself that you really want to open that app right now", with a "Try" button.

Example from

One Sec

When asking for personal details, it may help to play back what they mean, e.g., showing someone their age from their birth date, so an untrue entry feels harder to hold.

Example from

Hinge

During sign-up, one option is to ask people to sign their name as a commitment to use the product regularly, so skipping it later clashes with a promise they remember.

Onboarding. Commitment screens ask users to sign a pledge by drawing: "Promise yourself by drawing a checkmark:" with "I promise myself", then "Ready to commit? Draw a happy face!" with "I commit to myself".

Example from

Ahead

Consider replacing a plain 'Continue' button with a playful fist bump to seal a commitment, so moving on feels like agreeing to a pact, not just a tap.

Onboarding. After a checklist of personalised goals, a fist emoji prompts "Let's solidify it with a fist bump" and "Tap to continue"; tapping fills the screen with a celebratory burst of hourglass, phone and diamond emoji.

Possible impacts

Asking users to make a memorable commitment early on could reduce churn, as giving up later would clash with the promise they made to themselves.

Ahead A literal signature to commit

It's possible that users who've made a clear pledge build habits more easily, as skipping a day creates dissonance with the kind of person they said they'd be.

Prompting users to commit as they start something might increase use of related features like reminders, since ignoring them would clash with that commitment.

Making people face their own rules or notes when undoing them may increase discomfort, which could protect them but might feel frustrating if overused.

Turning a commitment into a playful gesture, e.g., a fist bump, might make onboarding feel more enjoyable while still sealing a pact users may later feel bound to.

Playing back what someone has entered, e.g., their age, could improve data accuracy, as an untrue detail stated plainly creates dissonance that makes lying harder.
