Design for behavioural change is a field of growing importance. Its growth is driven, on the one hand, by the fact that most of the problems we face as humanity are behaviour-based (e.g. threats to sustainability, health and well-being), and on the other by the notion that well-designed interventions can support people in changing their behaviour in the desired direction. This development has led to a growing number of design professionals, institutes and governmental organisations focusing on designing for behaviour change and consequently to a growing need for methodological support.

The Behavioural Lenses Approach is one such recent initiative towards a method that allows designers to use theory from the behavioural sciences to inform their work. Together with partners from creative industry and academia, we developed a theoretical framework (Hermsen, Renes, & Frost, 2014) and a toolkit (Hermsen, Ploos van Amstel, Van Eijl, & Renes, 2019) based on 5 so-called ‘lenses’, which relate to five general aspects of behaviour (change): Habits and Impulses; Knowing and Believing; Seeing and Realising; Wanting and Being Able To; Doing and Persisting.

In recent years, I have delivered a large number of presentations, workshops, and consultancy sessions based on the Lenses. Since I have left Utrecht University of Applied Sciences in 2020 I have not been available to do so anymore.
