Lancaster University’s interdisciplinary Institute for Advanced Studies (no, not that one) has been running a research programme, New Sciences of Protection, culminating in a conference, Designing Safe Living, on 10-12 July, “investigat[ing] ‘protection’ at the intersections of security, sciences, technologies, markets and design.”
The keynote speakers include the RCA’s Fiona Raby, Yahoo!’s Benjamin Bratton and Virginia Tech’s Timothy Luke, and the conference programme [PDF, 134 kB] includes some intriguing sessions on subjects such as ‘The Art/Design/Politics of Public Engagement’, ‘Designing Safe Citizens’, ‘Images of Safety’ and even ‘Aboriginal Terraformation (performance panel)’.
I’ll be giving a presentation called ‘Design with Intent: Behaviour-Shaping through Design’ on the morning of Saturday 12 July in a session called ‘Control, Design and Resistance’. There isn’t a paper to accompany the presentation, but here’s the abstract I sent in response to being invited by Mark Lacy:

Design with Intent: Behaviour-Shaping through Design
Dan Lockton, Brunel Design, Brunel University, Uxbridge, Middlesex UB8 3PH
“Design can be used to shape user behaviour. Examples from a range of fields – including product design, architecture, software and manufacturing engineering – show a diverse set of approaches to shaping, guiding and forcing users’ behaviour, often for intended socially beneficial reasons of ‘protection’ (protecting users from their own errors, protecting society from ‘undesirable’ behaviour, and so on). Artefacts can have politics. Commercial benefit – finding new ways to extract value from users – is also a significant motivation behind many behaviour-shaping strategies in design; social and commercial benefit are not mutually exclusive, and techniques developed in one context may be applied usefully in others, all the while treading the ethical line of persuasion-vs-coercion.
Overall, a field of ‘Design with Intent’ can be identified, synthesising approaches from different fields and mapping them to a range of intended target user behaviours. My research involves developing a ‘suggestion tool’ for designers working on social behaviour-shaping, and testing it by application to sustainable/ecodesign product use problems in particular, balancing the solutions’ effectiveness at protecting the environment, with the ability to cope with emergent behaviours.”

The programme’s rapporteur, Jessica Charlesworth, has been keeping a very interesting blog, Safe Living throughout the year.
I’m not sure what my position on the idea of ‘designing safe living’ is, really – whether that’s the right question to ask, or whether ‘we’ should be trying to protect ‘them’, whoever they are. But it strikes me that any behaviour, accidental or deliberate, however it’s classified, can be treated/defined as an ‘error’ by someone, and design can be used to respond accordingly, whether viewed through an explicit mistake-proofing lens or simply designing choice architecture to suggest the ‘right’ actions over the ‘wrong’ ones.
