Public attitudes towards human life extension by intervening in ageing

A number of biogerontologists have expressed an interest in intervening in the ageing process in order to extend the human life span. This study explored the attitudes of members of the Australian public towards the potential development and use of life-extension technologies and their attitudes towards the ethical, social and personal implications of life extension. Participants were presented with a vignette outlining the prospect of a “life-extension pharmaceutical” that could increase maximum life span by slowing the ageing process. While 65% supported such research, only 35% said that they would use a life-extension technology if one became available. Men were more supportive of research and more disposed to use life-extension technologies than women. Concerns about the potential ethical, social and personal implications predicted levels of overall support for, and intention to use, life-extension technologies. Our survey suggests that public attitudes towards life extension are neither overwhelmingly “pro” or “con” and in fact more nuanced than either proponents or opponents of life extension have often assumed.
