The imagination of possible scientific futures has a colourful history of interaction with scientific research agendas and public expectations. The 2017 annual UK Science in Public conference included a panel discussing this. Emphasizing fiction as a method for engaging with and mapping the influence of possible futures, this panel discussed the role of science fiction historically, the role of science fiction in public attitudes to artificial intelligence, and its potential as a method for engagement between scientific researchers and publics. Science communication for creating mutually responsive dialogue between research communities and publics about setting scientific research agendas should consider the role of fictions in understanding how futures are imagined by all parties.
