Learning without seeking?: Incidental exposure to science news on social media & knowledge of gene editing

by Joshua T. L. Anderson, Emily Howell, Michael A. Xenos, Dietram A. Scheufele and Dominique Brossard

Little is known about how incidental exposure to news, interpersonal discussion, and the diversity of social networks interact in social media environments and for science-related issues.

Incidental exposure could alleviate knowledge gaps between the Facebook users who are the most and least involved in interpersonal discussions about science.
