Small voluntary steps make larger ones more likely — provided they are genuinely voluntary.

## The principle
People act consistently with prior commitments, especially public and voluntary ones. A small initial agreement substantially raises the likelihood of a later, larger one.
**Mechanism:** Self-perception — people infer their own attitudes from their behaviour, and having acted a certain way, they update their view of themselves to match.
## Where it genuinely applies
- Designing a genuinely small first step that delivers real value — a free tool used once, a single meaningful setup action.
- Onboarding that sequences from trivial to substantial, where each step is independently worthwhile.
- Letting customers state their own goal, which they then act consistently with.
## The misuse
- Foot-in-the-door sequences where early steps exist only to create obligation and provide no value.
- Escalating commitments the customer did not understand they were entering.
- Using stated preferences against someone — "you said efficiency mattered, so you must buy this".
## The line
Behavioural principles describe how people actually decide. Using them to help someone reach a good decision faster is legitimate. Using them to push someone toward a decision against their interest is manipulation, and it is distinguishable by one test:
**Would the customer, fully informed about the technique and its effect on them, still be glad you used it?**
Loss aversion applied to a genuine risk passes. Loss aversion applied to an invented deadline does not. Social proof from real customers passes. Fabricated review counts do not.
If the honest application of this principle to would require inventing something, say so and stop. Do not produce the manipulative version with a warning attached.
## Step 1 — Test the fit
Does give you an honest application of this principle? State plainly what the truthful version would be. If there is no honest version — no real scarcity, no genuine social proof, no actual risk — say so and recommend a different principle.
## Step 2 — Apply it
Design the application for . Specify what changes: the copy, the structure, what information is presented and in what order.
## Step 3 — Know the limits
The effect requires the initial commitment to be freely chosen. Coerced or incentivised commitments produce no consistency pressure, because the person attributes their action to the incentive rather than to themselves.
It also decays: a commitment made months ago exerts little pull.
## Step 4 — Deliver
- The campaign or copy for
- A one-line statement of exactly how the principle is being applied
- The honesty check: would the customer be glad you used it, fully informed?
- What to measure to know whether it worked, and the counter-metric that would reveal it backfiring
## Never fabricate
Do not invent statistics, customer names, quotes, case-study numbers, testimonials, or research findings. If you need a figure you have not been given, write [NEEDS DATA] and say what you need. Realistic-sounding invented numbers are the fastest way to destroy credibility with an informed audience.
## Avoid
- Opening with a definition, a rhetorical question, or "In today's fast-paced world".
- The words "delve", "tapestry", "landscape", "game-changer", "unlock", "elevate", "seamless", "robust", and the construction "it's not just X, it's Y".
- Padding: any sentence that restates the previous one in different words.
- Evenly-weighted sections. Real arguments have a centre of gravity.
- Hedging every claim into meaninglessness. Take a position.
