Gain influence without authority: learn to shape choices and behaviour

Colleagues, clients and directors decide based on the situation they're in, not on your arguments. In two days you learn to read that situation and design it. You gain more influence on what they choose, even when you are not their boss.

For advisers, project leads, policy makers, account managers and managers who need to get others on board without being their boss.

What is influence?

Influence lives in the situation where the other person chooses.

Influence is the ability to change what another person chooses and does. Without formal authority, you gain influence through the situation in which the other person decides: what they see, what others do, how much effort a choice takes and what risk they feel. Learning to read and design that situation is the skill of influencing choices and behaviour. More influence is the result.

More on the method: the SUE Influence Framework.

Sound familiar?

The proposal is sound. The other person does nothing with it.

Scene 1

You backed the proposal with numbers. The director says "interesting" and it disappears into a drawer.

Scene 2

The client was enthusiastic in the meeting. Then you hear nothing more.

Scene 3

Your colleague from the other department says yes in the meeting and then simply works around you.

A standard influencing course teaches you to talk better. But your story was never the problem. The problem is the situation in which the other person decides.

What you learn

After two days you can do this.

You see which fears and habits hold the other person back, even when they do not name them themselves.

You stop rewriting your pitch for the tenth time. You design the moment the other person decides.

You use social proof, friction and framing on purpose. And you spot it straight away when someone uses them on you.

People come along, even though you're not their boss. They don't feel played, because they choose for themselves.

You learn this with Behavioural Design and the SUE Influence Framework: first understand why someone is not saying yes now, then design the situation in which they do.

The programme

Two days, with the person you need to bring along as the case.

Day 1

How people really decide

  • System 1 and 2: why a strong argument rarely tips the balance.
  • The SUE Influence Framework applied to your own situation: what is holding this person back right now?
  • Behavioural interview: how to hear in half an hour what the other person does not say in the meeting.
Day 2

Designing the decision

  • With SWAC you work out what has to change in the situation. Your story can then stay much as it is.
  • Prototyping and testing on a real conversation, proposal or process.
  • AI helps you analyse and find the words. So you can apply the method quickly after the training too.

A maximum of 16 participants. Both days you work on someone you really need to win over right now. So no textbook case.

How is this different from a regular influencing course?

You learn to design the other person's decision, even when you're not at the table.

In two days we got the basics of how to apply Behavioural Design in practice. Astrid can convey the importance of outside-in thinking in a clear, informative and interesting way. I now feel like applying this in my own daily practice.

Is this for me?

Honestly: not everyone is in the right place here.

Not for you if

  • you mainly want to practise difficult conversations and body language;
  • you are looking for a sales course with call scripts;
  • you want an academic degree in behavioural science.

For you if

  • there is someone you need to bring along now and you want to get to work on it the day after the training;
  • you're tired of arguments that go nowhere;
  • you want it to work even when you are not at the table yourself.

Arguments win you the debate. A well-designed situation wins you the people.

Frequently asked questions

One more thing

By changing the situation in which the other person decides, rather than arguing harder. Find out what they want to achieve, what worries them and what ties them to the old habit. Then make the choice you propose easier, more visible and less risky. That works with colleagues, clients and directors who do not report to you.

Start with one concrete decision you need from someone. Describe the behaviour you want to see and the moment that choice is made. Then look at what holds the other person back at that moment. Do that a few times and you are practising the skill of influencing choices and behaviour, and your influence grows with it.

How people really decide, how to map what drives and what holds back the person in front of you, and how to design and test interventions. For two days the person you need to bring along is your case, and you go home with a toolkit you use the following week.

Influencing without authority is getting people to choose what you propose when you're not their boss. Better arguments barely help. What matters is the situation in which the other person decides: what they see, what others do, how much effort it takes and what risk they feel. In the training you learn to read and design that situation.

Both. Persuasion is about what you say. Influencing is about the situation in which the other person decides. You learn both, with the emphasis on designing the decision. Because that works even when you're not in the room.

For advisers, project leads, policy makers, account managers and managers who need to bring others along without hierarchy. No background in psychology required.

Two consecutive days in Amsterdam, a maximum of 16 participants. English-language editions run several times a year. The next date is at the top of this page, and you'll find every date on the training page.

€ 1,490 excluding VAT, including the Behavioural Design Toolkit, lunch, the EQAC certificate, the AI Mentor after purchase and lifelong membership of the BD Club.

No. Manipulation works against the interest of the other person and stops the moment they see through it. Behavioural Design makes it easier for people to choose what they already want. We talk about the ethical line openly in the training.

Yes. For teams there is the Sprint: the same two days at your location, with your own case, for 5 to 24 participants.

Your arguments are good enough. What's missing is a situation in which the other person says yes.
