What Reassurances Do the Community Need Regarding Life Extension? Evidence from Studies of Community Attitudes and an Analysis of Film Portrayals

It is increasingly recognized that community attitudes impact on the research trajectory, entry, and reception of new biotechnologies. Yet biogerontologists have generally been dismissive of public concerns about life extension. There is some evidence that biogerontological research agendas have not been communicated effectively, with studies finding that most community members have little or no knowledge of life extension research. In the absence of knowledge, community members' attitudes may well be shaped by issues raised in popular portrayals of life extension (e.g., in movies). To investigate how popular portrayals of life extension may influence community attitudes, I conducted an analysis of 19 films depicting human life extension across different genres. I focussed on how the pursuit of life extension was depicted, how life extension was achieved, the levels of interest in life extension shown by characters in the films, and the experiences of extended life depicted both at an individual and societal level. This paper compares the results of this analysis with the literature on community attitudes to life extension and makes recommendations about the issues in which the public may require reassurance if they are to support and accept life extension technologies.
