More science than art: behavioural psychology meets digital product design

If you build it, they will come? Sometimes not.

Behavioural science has shown that people are not always rational and logical. Opportunity, motivation and timely triggers are all equally important to inspire action.

Behavioural design marries psychology and behavioural economics with human-centred design  to dramatically improve product outcomes for you and your customers.

What is behavioural design?

Design has an impact. It can not only influence how you feel but it can also shape the decisions you make. Changing behaviour can be hard as habits are ingrained. But behavioural design can support this change. It’s all about how we present choices within a design.

...if there are several ways of achieving the same goal, people will eventually gravitate to the least demanding course of action. In the economy of action, effort is a cost, and the acquisition of skill is driven by the balance of benefits and costs. Laziness is built deep into our nature.

— Daniel Kahneman

Why choose behavioural design?

How does it work?

A common challenge in product development is forgetting where we start from and where we want to go. Behavioural design places the emphasis on this trajectory and designs interventions along the way to guide us to the desired outcomes:

Behavioural design process


Start at the end

What is the ideal outcome? It should unify a user goal and a business objective.


What’s the current user behaviour?

Look at existing experiences. Examine the data.


Understand this behaviour

Why do users have it? What external and internal forces are driving it?


Ideate the ideal future behaviours

What behaviour can produce the desired outcome?


Identify frictions and opportunities

What’s preventing the user and what’s enabling them?


Create a hypothesis

What assumptions are being made? How can we test this? What does a successful criteria look like?
