In an opinion piece for Scientific American, Bryn Nelson calls on the scientific community and its allies to expose and counter the extremists who are using a variety of channels to propagate and popularize an interconnected web of conspiracy theories and outright lies about science, health and social issues. Nelson highlights how purveyors of misinformation deny reality, twist and redefine terminology, and use the trappings of “science” and “journalism” to add credibility to their efforts, often with the backing of well-funded industry and political groups. Nelson shares several examples of ways truth-lovers can help to counter disinformation. Image: World Health Organization via Wikimedia Commons
