Here's the Social Science One commission structure. Like editors-in-chief at scholarly journals, ultimate responsibility for Social Science One decisions falls to the co-chairs, Gary King and Nathaniel Persily, with input from commission members acting like an editorial board.
Commission members provide advice as issues arise in their areas of expertise, and as sounding boards for ideas and communications; those needing access to private Facebook information sign confidentiality agreements. Commission members help Social Science One stay in contact with their academic communities by soliciting and listening for suggestions and ideas, and helping get the word out about Social Science One activities. They may also participate in the peer review process in review cycles in which they are not applicants. Those who do not sign confidentiality agreements may apply for grants as part of commission activities, as our peer review process includes procedures to manage conflicts of interest. (There may be changes to this list as we continue to evolve.)
