Our call is to promote interdisciplinary research to reduce the spread of fake news and to address the underlying pathologies it has revealed. Failures of the U.S. news media in the early 20th century led to the rise of journalistic norms and practices that, although imperfect, generally served us well by striving to provide objective, credible information. We must redesign our information ecosystem in the 21st century. This effort must be global in scope, as many countries, some of which have never developed a robust news ecosystem, face challenges around fake and real news that are more acute than in the United States. More broadly, we must answer a fundamental question: How can we create a news ecosystem and culture that values and promotes truth? —Science Magazine
