SciLine, a service from the American Association for the Advancement of Science, provides journalists with high-quality scientific expertise and context—on demand and on deadline. As SciLine Director Rick Weiss wrote in an an October 27, 2017, editorial in Science, “… in the fight against misinformation, fact checking is often too little, too late. When it comes to stories about science—or about legislation, economics, or other domains where science can be informative—it would be far better to help journalists and the public get it right before having to call in the truth squads.” Founding support for SciLine was provided by the Quadrivium Foundation, with additional funding from the John S. and James L. Knight Foundation, the Rita Allen Foundation and the Heinz Endowments.
