Saadi Lahlou is Chair in Social Psychology in the Department of Psychological and Behavioural Science at the London School of Economics and Political Science. He directed 4 research units (in Consumer Research, Sociology of Organizations, Cognitive Science and Social Psychology), including the Laboratory of Design for Cognition, a large user lab developing augmented environments for office work. Prof. Lahlou has worked in industry R&D for 15 years, in government (French Prime Minister’s strategy unit), and academia. His current research focuses on behavioural change and design; especially involving ICT and participative design; training and digital ethnography. The recently published “Installation Theory: The Societal Construction and Regulation of Behaviour” is his 5th book. In this talk Saadi addresses…

1. “Installations” channel behavior. They have 3 layers: affordances, embodied competences, social regulation. Redundancy of 3 layers makes installations resilient.
2. For better activity support (better business) improve installation layers (design / training / rules).
3. Artificial agents in installations raise serious design tradeoff issues (semantic Rubicon, privacy, freedom of action). Changes should be designed with the stake-holders.
