Donald Green, Co-author, Disavows Popular Gay-Marriage Study Over Fraudulent Data

The co-author of a highly publicized study that claimed brief conversations with gay individuals could change people’s minds on same-sex marriage has retracted it over claims that his partner used fraudulent data.

Columbia University political science professor Donald Green published a retraction Tuesday for “When contact changes minds: An experiment on transmission of support of gay marriage,” after confronting co-author Michael LaCour, a graduate assistant at UCLA, over allegations of faked data, Politico reported.

The study was published in the December issue of Science magazine and received widespread media coverage from outlets such as The New York Times, The Washington Post and The Wall Street Journal.

“I am deeply embarrassed by this turn of events and apologize to the editors, reviewers, and readers of Science,” Mr. Green told Politico.
