The era of post-truth politics poses a new challenge for contemporary art practice. If populist politicians persuade the masses by simplified conceptions of reality, how can art highlight the neglected nuances and complexities of our contemporary moment? How can art foster critical discourse that is often abandoned when subscribing to simplified notions of reality? As part of the 100th anniversary of the Dada movement, the online anti-museum Dada-Data was established in 2016 to revive the ideas behind the revolutionary art movement. Mixing collages and hypertext, twitter and manifestoes, Instagram and readymades, the online platform provides a space to explore Dada, and connects its heritage with our everyday online life. Our session expands on the idea of Dada-Data.net. It asks how an engagement with the aesthetic tactics of Dada, can help develop critical vocabularies for confronting our era of post-truth politics mediated by information floods and ‘big data’. Since it has been pivotal to the Dada movement to approach art and reality as inextricably linked, this session explores whether and how Dada strategies such as alienation, anti-aesthetics, collage, fragmentation and irony, may contribute to face the complexities of our time.
