How were conflicts of interest managed for the Challenge reviews?
Given the volume of applications received and the compressed timeline for finishing the reviews, the NIH determined that it was necessary to recruit over 15,000 outstanding scientists to serve as mail reviewers (including some who would also be applicants). However, a Challenge applicant could only serve in the Challenge reviews as a mail reviewer and not as a study section member, and only for a study section(s) other than the one reviewing his/her application. Mail reviewers do not participate in the discussion or final scoring of the applications, and do not interact with other study section members.
