Themes Influencing without authority training
Influencing without authority training · 2 days · Amsterdam

You are right. And still they do not come along.

People do not decide on arguments, but on the situation they are in. In two days you learn to read and design that situation, so that colleagues, clients and directors say yes and act on it. Without hierarchy, without tricks.

For advisers, project leads, policy makers, account managers and managers who need to bring others along without being in charge of them.

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.

Classic influencing courses teach you to talk better. The problem is not your story, but 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 design the moment at which the other person decides, instead of rewriting your pitch for the tenth time.

You use social proof, friction and framing deliberately, and recognise when someone applies them to you.

You bring people along without authority, and without them feeling played: 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

  • From insight to intervention with SWAC: what has to change in the situation, not in your story.
  • Prototyping and testing on a real conversation, proposal or process.
  • AI as a help in analysis and wording, so you apply the method quickly after the training too.

A maximum of 16 participants. Both days you work on someone you need to bring along now, not on a case from a textbook.

How is this different from a regular influencing course?

Not conversation technique. A design method.

If what you mainly want is confidence in difficult conversations, a conversation skills course is the better choice. If you want your proposal adopted this month, you are in the right place.

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 are done persuading on arguments;
  • you want it to work even when you are not at the table yourself.

Frequently asked questions

One more thing

Influencing without authority is getting people to choose what you propose while you are not in charge of them. It does not work through better arguments, but through 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, with a difference. Persuasion is about what you say; influencing is about the context in which the other person decides. You learn both, but the emphasis is on designing the decision, because that also works when you are 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 all dates are 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 designs situations in which people find it easier to choose what they already want. In the training we discuss the ethical line explicitly.

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