Exploring serendipitous dialogue

Over the past decades there has been an increasing recognition of the need to promote dialogue between science and society. Often this takes the form of formal processes, such as citizen’s juries, that are designed to allow the public to contribute their views on particular scientific research areas. But there are also many less formal mechanisms that promote a dialogue between science and society. This editorial considers science festivals and citizen science in this context and argues that we need a greater understanding of the potential impacts of these projects on the individuals involved, both scientists and the public.
