Situating anticipation in everyday life: Using sensory methods to explore public expectations of synthetic biology.

Public involvement in technological anticipation is a common feature of contemporary sociotechnical innovation. However, most engagements abstract sociotechnical futures, rather than situating them in the everyday practices in which people are routinely engaged. Recent developments in synthetic biology have established the potential for 'drop in' replacements for ingredients in consumer products, particularly in flavour and fragrance markets. This article explains how a sensory methodology can be used to explore citizens' everyday experiences and how these can be used to ground anticipation of possible sociotechnical futures. The article uses a socio-historical approach to analyse and compare two practice domains - caring for families and hygiene and personal care - to show how biosynthetic futures can disrupt existing relations between people, objects and ideas. The implications for conceptualising publics in synthetic biology and for approaches to public engagement and participation are discussed more broadly.
