Citizen Science in Psychology: Challenges, Opportunities and Recommendations

Human society is characterized by an interest in understanding the world and its phenomena. However, for most of society, science is a distant endeavor, reserved for a select group and a wide gap exists between scientists and citizens. This gap is even more striking in psychology, where humans are the study subjects of interest. Citizen science (CS) is a recent approach that incorporates perspectives of non-professional scientists or “citizens” through their active participation in scientific research. Because CS remains largely unexplored within psychology, this review highlights the opportunities that CS can offer for our field. After situating the relation between science and society and the emergence of CS in the history of science, we provide an overview of existing definitions and models of CS, which we then synthesize into a new model. We also describe CS studies within the field of psychology. Crucially, we discuss the main opportunities and challenges of CS, zooming in on specific challenges that CS faces within psychology. Ultimately, this review aims to bridge the gap between psychologists and their study subjects, by stimulating the development and application of a citizen science approach within psychology.
