Influence for product teams
Use the science of influence in your product.
What makes it different
Advice built on how you already design and decide.
No two product people persuade the same way. One wins with data in the review; another wins with a prototype users love. The assessment shows which principles you rely on, so the advice fits how you actually work.
Your strongest principle and your biggest gap.
See which principle shows up in your onboarding and prompts, and which one never does.
A name for why your good flows work.
Most teams can't say why one flow works and the next one doesn't. Your result puts a name on what you do by instinct.
Plain, direct advice.
The full report tells you where your habits help users act and where they get in the way.
The line you shouldn't cross.
Every principle can become a dark pattern: a fake timer, a guilt-trip button, a review you wrote yourself. Users notice, and trust drops. Knowing the principle shows you where the line is.
Things to try in your next sprint.
The full report gives you words to try and a 30-day plan, so you test on real screens.
Free to start.
Your result is free and appears as soon as you finish. The full report is $49, and you decide after you see your result.
What's inside
Where each principle shows up in a product.
Your result covers all seven principles of influence. Here's what you get.
Your strongest approach.
The principle you reach for first, in a screen or in a meeting.
All seven principles, in plain words.
Reciprocity, liking, social proof, authority, scarcity, commitment and consistency, and unity, plus contrast, the amplifier that changes how a price or plan looks beside the one next to it.
Your biggest gap.
The principle you use least. Hold it up against the step where most users drop off.
Principle by principle, in the full report.
Where each one helps you, where it hurts you, and words to try.
How your product asks people to act. Each stage calls for a different principle:
Onboarding
Commitment and consistency: ask what the user wants to get done, then show them that goal on the next screen.The first win
Reciprocity: give real value before you ask for an invite, a permission or a card.The habit
Social proof: show what people like them already use, with true numbers.The upgrade
Scarcity and contrast: show what the free plan truly lacks, and set the plans side by side ethically.
And in the roadmap review: authority and unity. Bring evidence from users the room trusts, and frame the decision around the goal you all share.

What builders say
What product leaders and researchers say.
Builders and researchers on the research behind it.
“'Influence' is a book that made me a billionaire.”
Tobias LütkeFounder, Shopify
“If the President had to have one advisor with him at all times, my nomination would be Bob Cialdini, the world's most practical social psychologist, and the master of 'Influence'.”
Richard ThalerNobel Laureate, Behavioral Economics
“I would really encourage people to study books like 'Influence,' so you get a fundamental set of principles that you can apply online, offline, to different tools, to direct copy, to complex sales in big organizations…”
Tim FerrissBestselling Author
Questions
Questions people ask.
A short assessment from the Cialdini Institute that shows how you use each of the seven principles of influence, plus contrast. For a product person, it shows which principles you build into your work and which you leave out.
No. Each principle works because it helps people decide well with the information they have. Use it on something true and it helps users. Fake it, with an invented deadline or a made-up review, and users stop trusting the product.
Ask whether it would still work if the user could see exactly what you were doing. A true limit or a real review passes. A fake countdown does not.
No. Each question is a real work situation with two good moves, and you pick the one you would actually make.
The book explains the principles. The assessment shows which ones you use and which you skip, so you know where to start.
