A new initiative calls for journal reviewers to ask editors to request authors to provide data and supporting code/documentation before they agree to review the manuscript.  From The Peer Reviewers Openness Initiative: “We suggest that … reviewers make open practices a pre-condition for more comprehensive review. This is already in reviewers’ power; to drive the change, all that is needed is for reviewers to collectively agree that the time for change has come.”  To learn more about the initiative, click here.  To read the supporting paper, click here. (H/T to Political Science Replication)
