Long-term contributors are critical to the success of many projects; research about motivational drivers has attracted the attention of many scholars. Prior literature has argued that values are motivational constructs linked to behavioral outcomes, and value orientations differ among demographic groups and cultures. In this paper, we assess the value orientations of volunteers who contribute to Zooniverse - an online platform that connects the public and researchers who collaborate on scientific research. We conducted an online survey (N=5,436) to measure the value orientations of Zooniverse contributors using Schwartz’s’ Portrait Values Questionnaire (PVQ). We found the most salient value orientations of the population were achievement, self-direction, and security. Value prioritization differs slightly among some demographic groups. We present strategies for motivating contributions based on value orientations in the discussion.enparticipant surveyvalue prioritieshuman valuescitizen scienceText/Conference Paper10.1145/3593743.3593782
