ALMA is strongly committed to ensure that the proposal review process is as fair and impartial as possible. Analysis of the proposal rankings in previous cycles has identified systematics that may signify the presence of biases in the review process (see Systematics in the ALMA Proposal Review Rankings). In an effort to reduce biases as much as possible, ALMA will use a dual-anonymous proposal review process starting in Cycle 8.
ALMA Cycle 8 Call for Proposals: Dual-Anonymous Proposal Review Process
In a dual-anonymous review, the proposal team does not know the identity of the reviewers and the reviewers do not know the identity of the proposal team. While proposers will still enter their names and affiliations in the ALMA Observing Tool (OT), this information will not appear on the proposal cover sheet, nor in the tools used by the reviewers. It is the responsibility of the proposers to ensure anonymity is preserved when writing their proposals. Detailed guidelines are given here.
