This collective article presents a theoretical kaleidoscope, the multiple lenses of which are used to examine and critique citizen science and humanities in postdigital contexts and from postdigital perspectives. It brings together 19 short theoretical and experiential contributions, organised into six loose groups which explore areas and perspectives including Indigenous and local knowledge, technology, and children and young people as citizen researchers. It suggests that this collective approach is appropriate because both postdigital and citizen research are founded on and committed to collaboration, dialogue, and co-creation, as well as challenging the tenets and approaches of traditional academic research. In particular, it suggests that postdigital transformations in contemporary societies are both changing citizen science and humanities and making it more important.
