After a vote that banned same-sex marriage in California, David Fleischer and his team at the Los Angeles LGBT Center set about to find out why, and attempt to reduce prejudice by going door-to-door. Could they change peoples’ minds with a conversation? The answer surprised everyone.

Dave Fleischer runs the Leadership LAB at the Los Angeles LGBT Center. The LAB helps both LGBT and straight leaders improve their ability to reduce prejudice and change the hearts and minds of voters. After an independent evaluation of the LAB’s effectiveness was published in the April 8, 2016 issue of the peer-reviewed journal Science, media coverage for the LAB’s work included this New York Times Magazine story. In September 2016, the American Political Science Association’s Experimental Research Section gave Dave its public service award for his body of work.
