Elicit a small consistency cue before the main ask

Get a small, genuine agreement or self-description before the main request — people act consistently with what they’ve said.

Why it works

Commitment and consistency (Cialdini’s third principle, deepened in Pre-Suasion) holds that people align subsequent behavior with prior public commitments. A small pre-commitment raises the psychological cost of refusing the main ask, not through guilt but through identity consistency — the person has already said something true that aligns with the ask.

How to do it

1. Find a genuine, small agreement the person can honestly make that is directionally aligned with your goal.
2. Ask for that agreement explicitly and get a verbal or written response — active commitments are stronger than passive ones.
3. Transition to the main ask by connecting it to what they just said: "Given that you just said X, this might make sense for you."

Evidence

Commitment and consistency effects are among the most replicated influence findings, including foot-in-the-door studies. Pre-suasion situates commitment as a temporal setup — priming before the ask — extending the classic findings. (observational)

Overly manufactured consistency cues can feel manipulative if the person realizes the chain; the effect relies on the initial agreement being genuine.

Common mistake

Asking a leading question designed to trap agreement rather than seeking honest alignment — the person notices and the technique destroys credibility.
