“…For instance, during my empirical research I have found that entertainment is implicit in the framing of informal public engagement, with organisers striving to design events which laypeople will, above all, attend, and ideally enjoy; that enjoyment is constantly cited by audiences and participants as a key feature of their experience (with interviews with these actors, at public engagement events or deliberative processes, almost invariably starting with some variation of: 'it's really good, I'm enjoying it'); and that the necessity of pleasurable aff ects is articulated with normative passion by communicators who argue not just that they know what their audiences want but that science-as-leisure can have profound eff ects on participants. Delight, interest, enthusiasm, and pleasure all leave their traces on the practice of public engagement (see also Pearson, 1997;Rowe et al, 2010;Simonsson, 2006;Wilkinson et al, 2011) -even those forms, such as consensus conferences, which are more formal, perhaps drier, in nature (Powell et al, 2011). It is worth, I think, running the risk of labouring this point.…”
