Toward an international definition of citizen science

Abstract

Public participation in scientific projects is flourishing globally as part of projects labeled “citizen science” (CS). Already, a number of professional networks for CS stakeholders have been founded, for example, the US-based Citizen Science Association, the European Citizen Science Association, and the Australian Citizen Science Association. As citizen science (CS) continues to grow, researchers and participants should move toward a shared understanding of what the practice is, what it is not, and what criteria CS projects must fulfill to ensure high-quality participatory research.

In fact, the label CS is currently assigned to research activities either by project principal investigators (PIs) themselves or by research funding agencies. Against this backdrop, critical observers of CS, such as Guerrini et al. (3), have drawn attention to important legal and ethical issues including intellectual property and scientific integrity. Similarly, Vayena and Tasioulas (4) note the importance of protecting the interests of research participants in biomedical participant-led research, and Buyx et al. (5) note the need for a solidarity-based practice of CS to fully exploit its potential, making “every participant a PI.” In light of the rapid growth of CS, present concerns, and calls for further improving the value of CS, we see several issues for policymakers, funding agencies, and citizens. Specifically, we believe that researchers and participants should move toward a shared understanding of what CS is, what it is not, and what criteria CS projects must fulfill to ensure high-quality participatory research (6). Establishing criteria will help ensure that CS projects are rigorous, help the field flourish, and where applicable encourage policymakers to take CS project data and results seriously. Politicians throughout Europe understand CS … [↵][1]1To whom correspondence should be addressed. Email: florian.heigl{at}boku.ac.at. [1]: #xref-corresp-1-1
