What is behavioural and decision science consulting?

Behavioural and decision science consulting applies rigorous research on how people actually decide and act to real organisational challenges. Rather than relying on opinion or convention, it uses insights and methods from behavioural economics, psychology and decision science to design strategies that change behaviour and deliver measurable outcomes. Aeccess is a Swiss consultancy specialising in this field, working with corporations, public institutions and government entities.

What does Aeccess do?

Aeccess drives activation and transformation, built on behavioural and decision science. Activation moves people to act: adopt, buy, participate, switch. Transformation enables organisations to do things differently: lead, decide, change. Both rest on the same scientific foundation and are guided by one consistent framework, delivered as partners alongside the people we advise.

How is Aeccess different from traditional strategy and management consultancies?

Traditional consulting often ends where implementation begins: actual human behaviour change. Aeccess goes further. We are specialised, senior-led and lab-advised, providing recommendations that are scientifically substantiated, developed in partnership with leading academic institutes, and built for adoption rather than for slide decks. You work directly with proven experts, supported by AI in our workflow, so depth comes without the overhead of large project pyramids.

How does Aeccess measure behavioural impact?

In the way that suits your challenge: from clear indicators, to qualitative evidence, to randomised controlled trials. We define the measurement logic together before we start, not after. And if you prefer no measurement, we will still tell you honestly what is expected to work and what is not.

Is behavioural and decision science just academic theory, or is it practical?

Science is our foundation, not our product. Clients do not receive academic studies or research papers; they receive straightforward decisions, strategies, policies, products, services and measures they can trust. We do the deeper thinking so organisations can decide more easily, turning rigorous research into tangible actions.

Why use behavioural science instead of conventional consulting methods?

Most strategies fail not on paper but in behaviour, when customers, employees or citizens do not act as planned. Behavioural science addresses this directly, identifying what truly drives decisions and designing for it. This produces advice that is more robust, because it is grounded in evidence rather than assumption.

Is this change management?

Change management organises change through plans, training and communication. Aeccess makes sure change actually takes hold in behaviour. We speak of activation when people need to adopt something new, and transformation when an organisation needs to work differently. Change is often the call; behaviour is the lever.
