In the Humanities knowledge about the performativity of the everyday, the institutional, the social, the urban, the political etc. is expanding. Combined with performative art practices this knowledge can be used to build hypotheses for experimental intervention and further practical exploration. The agenda of this kind of experimentation is often twofold: On the one hand side knowledge of Humanities is tested in different fields, thereby questioning and adding to it from the perspective of cultural practice. On the other hand, practice triggers with the question how the knowledge produced by Humanities can actually be used for transformative change, even if only on a micro level. This experimental turn of the Humanities can take very different forms and shapes according to the specific disciplines and practices involved, like for example: analyses in media history can inform public media experiments; ethnographical observation can be combined with performative intervention in a feedback loop of action and reflection; a critique of archives can lead to the creation of new forms of collection; etc.
