The new Wikipedia page on “Design for behaviour change” starts as follows:
“Design for behaviour change is a sub-category of design, which is concerned with how design can shape, or be used to influence human behaviour. All approaches of design for behaviour change acknowledge that artefacts have an important influence on human behaviour and/or behavioural decisions. They strongly draw on theories of behavioural change, including the division into personal, behavioural and environmental characteristics as drivers for behaviour change. Areas in which design for behaviour change has been most commonly applied include health and wellbeing, sustainability, safety and social context, as well as crime prevention.”
The UK spelling seems to imply that the page originated on this side of the pond, most probably on the British isles.
