Last month, This American Life did a story about canvassers who identified a way to go door to door and change people’s minds on issues such as same sex marriage and abortion rights. The story cited data that had been published in the journal Science. It proved that the canvassers could influence peoples’ views. In a big way. An author of the study asked Science to retract it because he believed some of the data gathered by his co-author was faked, so TAL had to issue a retraction.
