In the 12 December 2014 issue, Science published the Report “When contact changes minds: An experiment on transmission of support for gay equality” by Michael J. LaCour and Donald P. Green (1). On 19 May 2015, author Green requested that Science retract the paper because of the unavailability of raw data and other irregularities that have emerged in the published paper. Science is urgently working toward the appropriate resolution, while ensuring that a fair process is followed. In the meantime, Science is publishing this Editorial Expression of Concern to alert our readers to the fact that serious questions have been raised about the validity of findings in the LaCour and Green paper.
