Lever: Lock-in Commitment
Aim: Stack small, visible signals of progress so momentum builds and back-tracking feels awkward.

Now:

People start with good intentions, then disappear. Nobody notices. Nothing’s lost. Nothing changes.

Then:

Each step adds weight. Private stake, public trail, role tied to progress. Now there’s something to lose and something to prove.

Trigger test

Great, run this tactic.

Build

Make it real

Ask for a one-line pledge and a fallback plan.
“Publish draft by 30 June. If blocked, email Sam.”

  • Is the goal phrased as verb + object + date?
  • Is the fallback specific and realistic?

Let them pick the cost

Require a small commitment, but let users choose how they pay it with time, effort, or money.
This gives them autonomy and skin in the game.

  • Is there always a £0 option to avoid exclusion?
  • Do both paths require visible effort or investment?
  • Have you tested drop-off at this step?

Capture a private signal

Ask for something they’ll feel, but that’s not public.
Examples:
Product: Type initials, take in-app selfie, or tick “I’m ready”
Programme: Sign a digital commitment card, log progress in their profile.

  • Is the input active, not just a checkbox?
  • Will they see it again later?

Add a peer mirror

Let them nominate a peer to view their progress.
Example: “Choose a buddy who’ll see your bar fill as you go.”

  • Is this clearly opt-in?
  • Is the other person notified, and are boundaries clear?

Share the pledge (for support)

Guide them to post their commitment to a small group, framed as a request for backup.
Example: “I’ve committed to finish Module 1 by Friday. Give me a nudge if I stall.”

Is the tone supportive, not braggy?

Can they choose the audience size (1–10)?

Is the share reversible?

Escalate the ask

Once they hit the first milestone, raise the bar slightly.

Connect progress to identity

Tie visible progress to evolving roles, streaks, or badges.

  • Does each role or streak level feel earned?
  • Would losing it feel like a step back?

Build reciprocity

Ask users to contribute something small to help others.
Only then unlock their next badge, tip, or milestone.

Example:
“Share one lesson from Week 1 to unlock your progress badge.”
“Post one tip for the next cohort.”

Metrics

Log baseline numbers before drills. Then track gains.
