Citizen science as a means for increasing public engagement in science: presumption or possibility?

Citizen science is often assumed to increase public science engagement; however, little is known about who is likely to volunteer and the implications for greater societal impact. This study segments 1,145 potential volunteers into six groups according to their current engagement in science (EiS). Results show groups with high levels of EiS are significantly more interested in volunteering and more likely to participate in various research roles than those with lower EiS scores. While citizen science benefits some in science and society, its use as a strategy to bring about positive shifts in public science engagement needs to be reconsidered.
