@article {642, title = {Encouraging Work in Citizen Science: Experiments in Goal Setting and Anchoring}, year = {2016}, abstract = {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.}, doi = {10.1145/2818052.2869129}, attachments = {https://crowston.syr.edu/sites/crowston.syr.edu/files/CSCW-abstract.pdf}, author = {Corey Brian Jackson and Kevin Crowston and Gabriel Mugar and Carsten {\O}sterlund} }
