Everything you do as a legal professional, from writing contracts to advising boards to structuring deals, depends on human behaviour. People don't act on advice because it's correct. They act when the decision environment is right. Behavioural Design gives you that second layer of your profession.

Advice, contracts, compliance. Again and again: the legal solution is clear but the behaviour does not change. The question is not whether you recognise this. The question is how you close that gap.
The analysis was thorough. The recommendation was clear. The client nods. Nothing changes. There is a gap between understanding and deciding.
It is legally airtight. Every clause is there. In practice, people act as if the key provisions do not exist. Contracts are designed for judges, not for behaviour.
Everyone received it. Everyone signed it. Nobody acts on it. Compliance that relies on awareness alone is not compliance that changes behaviour.
The e-learning was completed, the certificate was issued. Six months later, the same issues appear. Knowledge and behaviour are different things.
Status, sunk costs, loss aversion. The best legal analysis in the room loses to the dynamics around the table. Designing for the boardroom means designing for those dynamics.
Both sides are stuck. The positions are clear. The interests are not. Behavioural negotiation is a different discipline from legal negotiation.
The documents are there. The people say the right things. The behaviour tells a different story. Designing due diligence for behaviour gaps is a different skill.
The analysis is correct, the recommendation is clear, the structure is excellent. Nobody acted on it. Format, framing and timing matter more than correctness.
Facts do not move people by themselves. Framing, anchoring, narrative, social proof. Designing for persuasion is not the same as designing for correctness.
Most behavioural science knowledge is locked in academic papers and consultancy reports. SUE built its own method, the Influence Framework, which translates that knowledge into a practical step-by-step process any HR professional can apply, without a scientific background.
No academic theory — you work on your own HR case during the training and go home with a fully worked-out plan
Built on Kahneman, Cialdini and Thaler, scientifically grounded but accessible for practitioners
Our own method, the Influence Framework is not taught anywhere else, described in the #1 management bestseller
16 years of experience, from ING to Heineken to the Dutch Government: the method has been proven on the biggest HR challenges in the Netherlands

The lawyers among them have one thing in common: afterwards they look at advice, contracts and client behaviour differently.
In two days you are introduced to a new way of thinking and new models that make you question a lot of traditional insights. I leave the Academy with so much energy to actively apply the principles and to link them to HR and employer branding.
Gained an enormous amount of knowledge in 2 days, which you also immediately learn to apply in practice. Besides the fact that the training is a huge eye-opener, it is also a lot of fun.
A fun, interactive and easy way to understand complex human behavior and decision making. For everyone who needs to pitch an idea or implement process or policy.
The mix of theory and practice worked well. I liked that you could immediately apply the material in practice. I have no points for improvement. One of the best trainings ever!
At the Academy you learn a lot about behavioral change and how to apply it in a short period of time. The training flew by and was very well put together. Amazing how complicated material comes to life in a fun and interactive course!
The BDA gave me more insights in behaviour that is also seen in the workplace. It taught me to see things differently and made me aware we can make a big impact on behaviour with small things.
Very inspiring trainers with deep knowledge. I want to incorporate behavioural design into our design thinking workshops.
Valuable training where existing knowledge is clearly incorporated into practical frameworks, making behavioral design accessible to everyone.
This is really interesting stuff. I will definitely start using Behavioural Design in my work. Challenging and inspiring.
What I really like about these days is that you constantly connect to your own case, so you can experience this right away. Super valuable!
Not abstract knowledge. Concrete changes in how you approach advice, compliance and behaviour change in legal contexts.
You use the Influence Framework as your starting point: what drives these employees, what's holding them back, what context helps?
You shape the work environment so that the desired behaviour becomes the easiest choice, not just the most communicated one.
You share a common framework with your team: goals, anxieties, habits, context, friction, triggers. HR decisions become more concrete and better grounded.
Most participants start without any prior knowledge. The training teaches you the behavioural science you need, linked directly to your own legal practice. No academic theory for its own sake, just actionable insights you can apply the very next day in your advisory work, compliance programmes or contract design.
You learn the SUE Influence Framework: a method for analysing why employees do what they do, and for designing HR interventions that genuinely work. You work on your own HR case during the training, such as onboarding, retention, culture change or wellbeing, and go home with a fully worked-out strategy you can apply the next day.
The training is most valuable for experienced legal professionals. You've got the practical experience. The training gives you the scientific framework that backs up your intuition and sharpens your approach. Many participants say afterwards: I was already doing parts of this, but now I understand why some advice gets acted on and other advice doesn't.
A deliberately mixed group: HR professionals, marketers, communication advisers, policymakers and leaders all together. Maximum 16 participants. That mix is what makes it valuable, because you learn not only from the content but also from how people in other sectors deal with similar behavioural challenges.

Start with the Fundamentals. That gives you the complete Behavioural Design framework: the Influence Framework, the JTBD method and all core tools. The Deep Dive Legal builds on that with legal-specific applications. Without the Fundamentals, the Deep Dive lacks its foundation.
The Fundamentals course is the broad foundational training: 2 days live (or 33 online lessons) in which you learn the complete Behavioural Design framework. After that, you can apply it to any legal challenge. A Deep Dive training lasts 1 day and goes deep on one specific topic, such as compliance behaviour, advisory persuasion or contract design. If you do both, the Fundamentals course is always the first step.
