The Small Yes

The effect

"A tiny commitment now makes a big commitment later feel consistent."

The method

People want their actions to feel coherent with their past actions. Get a small 'yes' (a quiz, a free trial, a low-stakes share) and the next 'yes' rides on momentum.

The ethics spectrum

Same hack. Three very different choices.

White hat

Small step is genuinely useful on its own; the larger ask is honest and optional.

Grey hat

Small step's main purpose is engineering the next ask.

Black hat

Small commitment was a trick — the real ask is wildly different in scope or cost.

The template

A formula you can steal

Ask for [LOW-COST ACTION] → deliver real value → make [LARGER ASK] feel like the natural next step.
Spotted in the wild

Where you've already seen this

  • Online quizzes ('What's your skin type?') ending in a custom-product checkout.
  • Charities asking you to sign a petition before asking for a donation.
  • Free trials that quietly auto-convert to annual plans on day 14.
When to use it

When the small step is itself genuinely useful and the bigger ask is a fair next step for someone who got value from the small one.

When NOT to use it

When the small ask is a Trojan horse for a much larger commitment the user couldn't have anticipated.

The 5-minute practice

Try the trick today

Map your funnel as a chain of yeses. Mark each step with the perceived cost. If any jump is more than 3× the prior step, you're losing people there.
