Each principle in plain words, one honest way to use it, and the manipulative version to avoid.
CTFM Team
Robert Cialdini is a psychologist who spent years studying why people say yes. His book Influence set out six principles, and a later book, Pre-Suasion, added a seventh.
You have met all of them, probably today. The useful thing is that Cialdini himself draws a line. On one side, influence that points at something real. On the other, influence that makes it up. That line is the whole point of this post.
How to read this
Each principle gets three things: what it is, one honest use, and the version that gets you in trouble. From the outside, the honest use and the dishonest one often look the same. That is exactly why people drift across the line without noticing.
People feel a pull to give back when they have been given something.
Honest use: give something genuinely useful before you ask for anything. A tool, a template, a straight answer to a question in public with no pitch attached.
The manipulative version: the fake gift. A "free audit" that is a sales call, a "gift" that arrives with an obligation attached. People notice, and the resentment is worse than if you had just asked.
Once someone takes a small step, they tend to act in line with it.
Honest use: design a genuinely small first step. A five-minute trial, one free sample task, a single question answered. Let people prove the thing works before they commit properly.
The manipulative version: the tiny yes that traps. Getting someone to agree to something trivial, then treating that as consent to something much bigger. Prechecked boxes live here.
A real small step
Reversible, useful on its own, and honest about what comes next.
A trap
Only useful to you, hard to undo, and quiet about what it commits them to.
People look at what others like them are doing, especially when they are unsure.
Honest use: show real customers, named where they allow it, ideally similar to the reader. Specific beats numerous. One detailed review from someone in the same situation outperforms fifty generic five-star ratings.
The manipulative version: fake reviews, bought followers, invented user counts. Beyond being regulated in several markets, it is recognisable. Real reviews mention a specific annoyance. Fake ones praise in general terms and never do.
The counterintuitive bit
A handful of reviews that admit a real drawback converts better than a wall of perfect ones. The mild criticism is what makes the praise credible. Most companies suppress exactly the reviews that would help them.
People say yes more readily to people they like, and liking comes from similarity, praise and cooperation.
Honest use: sound like a person. Write the way you talk. Admit what you do not know. Be genuinely useful in public without keeping score.
The manipulative version: manufactured rapport. Fake friendliness in a sales script, hollow flattery, pretending to share a background you do not have. It reads as false and it costs you the trust you were trying to build.
Honest use: show your actual work. Publish your reasoning, your methods, the things you got wrong. Real authority is demonstrated rather than claimed.
The manipulative version: borrowed or invented credibility. Meaningless awards, vague "as featured in" logos where the mention was a single passing reference, implied credentials you do not hold.
Honest use: real constraints, said plainly. A cohort that actually starts on a date. Stock that genuinely runs out. A price that is genuinely rising, and then does.
The manipulative version: the fabricated deadline. Timers that reset on reload, "only three left" on an infinite digital product, a sale that ends every night for a year. It works once per visitor and then converts a customer into a sceptic.
The seventh, from Pre-Suasion. This one is about shared identity rather than mere similarity. Not "people like you" but "people who are us".
Honest use: serve a specific group properly and speak their language accurately. A tool built for wedding photographers, described in the words wedding photographers actually use, does this without any technique at all.
The manipulative version: claiming a group you have not earned. Adopting a community's language and symbols to sell to them while having no real connection or commitment. Communities detect this fast and the backlash is proportionate.
Cialdini distinguishes influence that reflects something true from influence that fabricates it. That gives you a usable test.
Is the thing I am pointing at real?
Real scarcity, real proof, real expertise, real generosity. If yes, you are using the principle. If no, you are faking the signal.
Would the customer still be glad if they saw the plan?
Imagine them reading your internal document explaining why the page is built this way. Honest persuasion survives that. Manipulation depends on them not seeing it.
Does it still work if they notice?
This is the sharpest version. Honest influence works better when understood. Manipulation stops working the moment it is spotted.
Look down the fake column. Every one of them works in the short term. And every one spends the same asset, which is whether people believe you next time.
Robert B. Cialdini, Influence: The Psychology of Persuasion, for the original six principles.
Robert B. Cialdini, Pre-Suasion, for the seventh principle, unity.
Both principles and the ethical distinction described here come from Cialdini's own published work. The honest and manipulative examples are our own application of it.
