Study of attitudes to same-sex marriage retracted over 'fake data'

Prof Donald Green 'embarrassed' over claims of errors by his co-author in study that found a conversation with a gay canvasser could soften attitudes

The senior author of a study claiming to find that a brief, face-to-face conversation with a gay political canvasser had the ability to soften the opinions of those opposed to same-sex marriage has retracted its findings, claiming there were errors in his co-author's work.

The study, which was published in Science in December and was widely covered in the media, found support for same-sex marriage climbed among voters who had a single conversation with a gay or lesbian canvasser. In addition, the authors found that the changed views not only lasted for at least a year, but also positively influenced the opinions of other members of the household.
