Reciprocity
What is reciprocity in UX?
Reciprocity is the pull to return a favour - give someone something first and they feel quietly obliged to give back. Lead with genuine value and a later ask lands softly; open with the ask and it reads as a demand.
Also known as: reciprocity principle, give and take
The demo
The same newsletter sign-up, two orders of play. Switch between asking first and giving first, and notice how much warmer the request feels once you've already been handed something.
Switch the order and feel the same ask change weight.
What this demo shows (text version)
A newsletter sign-up shown two ways. In "ask cold" mode it leads straight with the request: "Subscribe to our newsletter" and a button, with nothing offered first - it reads as a demand for your email.
In "give first" mode it offers a genuinely useful free resource - a UX checklist you can download with no sign-up - and only after you have taken it does it invite you to subscribe. Having already received something, the same request feels fair to accept rather than pushy. The ask is identical; only the order changes, which is reciprocity: give before you ask and the favour gets returned.
Asked cold, the request felt like a hand out for your email; handed something useful first, the same request felt almost polite to accept. Nothing changed but the order - value, then ask, instead of ask, then maybe value. That small debt is reciprocity doing the persuading.
The honest version gives something genuinely useful with no strings - a real tool, a real answer - and only then invites more. The manipulative version gives a worthless "gift" to manufacture the obligation, or makes the gift conditional on the ask so it was never really given. If the thing you lead with isn't valuable on its own, you are faking the favour.
Order is the whole lever. Most flows ask before they give - sign up to see if it's any good - which spends goodwill you haven't earned yet. Flip it: let people get value first, and the conversion that follows is something they choose rather than something you extract. It works because it is, genuinely, the fairer deal.
