A one-on-one-encounter can also be a participatory art-based research format as a specific version of an improbable assembly. Two people are connected in an exclusive constellation, in which they talk to each other or act together and by doing so exchange and produce knowledge. Thus, this interaction is at an interface between private and public and may contain confidential moments and information that should be handled with care by the researcher and all people involved. Therefore, the research setting has to take into consideration, how to deal with this issue of privacy and the atmosphere of conspiracy that may result.
