To better explore and understand the public's perceptions of and attitudes toward emerging technologies and food products, we conducted a US-based focus group study centered on nanotechnology, nano-food, and nano-food labeling. Seven focus groups were conducted in seven locations in two different US metropolitan areas from September 2010 to January 2011. In addition to revealing context-specific data on already established risk and public perception factors, our goal was to inductively identify other nano-food perception factors of significance for consideration when analyzing why and how perceptions and attitudes are formed to nanotechnology in food. Two such factors that emerged-altruism and skepticism-are particularly interesting in that they may be situated between different theoretical frameworks that have been used for explaining perception and attitude. We argue that they may represent a convergence point among theories that each help explain different aspects of both how food nanotechnologies are perceived and why those perceptions are formed. In this paper, we first review theoretical frameworks for evaluating risk perception and attitudes toward emerging technologies, then review previous work on public perception of nanotechnology and nano-food, describe our qualitative content analysis results for public perception toward nanofood-focusing especially on altruism and skepticism, and discuss implications of these findings in terms of how public attitudes toward nano-food could be formed and understood. Finally, we propose that paying attention to these two factors may guide more responsible development of nano-food in the future.
