%0 Generic %D 2016 %T Encouraging Work in Citizen Science: Experiments in Goal Setting and Anchoring %A Corey Brian Jackson %A Kevin Crowston %A Gabriel Mugar %A Carsten Ă˜sterlund %X This paper describes the results of an online field experiment where we designed and analyzed the effects of a goal-setting tracker in an online citizen science project - Floating Forest. The design of our tracker was influenced by psychology theories of anchoring and goal-setting. Our results of our experiment revealed: (1) setting goals increases annotations in a session; (2) numeric anchors influence goals; and (3) participants in the treatment who saw a prompt but did not set a goal, contributed more annotations than the participants in the control group. Our research shows how goal-setting and anchoring combine to increase work in online communities. %B ACM Conference on Computer Supported Cooperative Work & Social Computing (CSCW) %R 10.1145/2818052.2869129 %> https://crowston.syr.edu/sites/crowston.syr.edu/files/CSCW-abstract.pdf
