Non-experts' participation in processes of scientific knowledge creation: The case of Citizen Science

Public participation in science and technology, is currently being encouraged in order to fulfil the calls for a more engaging, transparent, and ethical way of governing technoscientific innovation. Several institutional documents argue for the need to enrol non-scientists into research programs; funding schemes devoted to public engagement seem to be paving the way for new baselines for knowledge creation and innovation paths that include the contributions of citizens. Citizen Science stands out as an opportune movement to lead non-scientists to contribute to scientific research projects and technological innovation, and it has given rise to a broad debate intersecting many sociological aspects linked to participation and community empowerment. However, the participation of non-scientists in data collection, analysis, and interpretation is not totally new; yet it has not had the same value across time, nor has it always been considered desirable. Indeed, volunteers' engagement and amateurs' contributions have been regulated differently compared to the current rhetoric of participation. This paper gives an account of the evolution of participation of non-experts through the lens of Science and Technology Studies, investigating its desirability, how it is governed, and whether it matches the promises of Citizen Science practitioners.
