Group Know-How and Joint Expertise

Date: Monday 4 and Tuesday 5 September 2023 ​​

People act together in all kinds of collaborative work and performance. Dyads and small groups, in particular, exhibit rich forms of joint intelligence in action, both in everyday skills and in the striking forms of expertise found in sport, music, and many domains of professional activity.

Conceptual work on joint action and shared agency is increasingly responsive to and suggestive for empirical research, especially in cognitive neuroscience and experimental psychology. Yet there has been less coverage in social ontology of the topics of know-how, expertise, and skill. What grounds the ways that some groups move or perform effectively together? Is there group know-how, and (if so) how does it relate to individual know-how? Is there a solid notion of joint expertise, and (if so) how can we best study its nature and its component processes? This workshop focuses on this topic, bringing together researchers with different approaches to this topic. Both specific case studies from the live practice domains of expert performance and immersed and sustained cognitive-ethnographic studies of group know-how and joint expertise will be presented at the workshop. This will be combined with more theoretical approaches of the topic of joint know-how. We believe this will significantly enhance our social ontology in these domains.
