Scientific conferences are not only sites of knowledge exchange and networking. They are also spaces of valuation that are constitutive of epistemic cultures. At conferences, scholars (re-) negotiate what counts as good research, what kind of scholarship is considered valuable and which epistemic properties matter for their field. This negotiation sometimes happens explicitly, but more often through evaluative acts: statements of reasoning and justification, questions and remarks, and evaluative emotional utterances that include literal and figurative expressions of appreciation, scepticism, rejection, etc. Combining conference ethnography with a pragmatic approach borrowing insights from linguistics offers a way to identify and interpret such evaluative acts in conference talk. An analysis of data from the 3rd International Forest Policy Meeting (IFPM3), a virtual event with participants from across the globe, serves as illustrative case. Text materials generated through observing participation (field notes, transcripts, chat comments and abstracts) show how forest policy researchers ascribe worth to studies characterised by methodical rigour and praxis orientation, and guided by an objectivistic ideal of science. However, the latter was also challenged by panelists who enthusiatically appraised reflexive research that acknowledged the role of emotions in knowledge production.The IFPM3 case shows that conferences offer a unique space for observing academic valuation practice. Exploring how scholars enact values through conference discourse will not only help to better understand the specificities of particular research fields and their epistemic cultures. It can also more generally enhance the understanding of how social and epistemic levels in science intersect.
